What is the importance of Contribution to Open Source Code ?

The Linux community World wide contains many students who are developing the code either out of Interest or as part of their academic projects.

But most of the colleges doesn’t have the proper environment suitable for Open Source Projects (Except for top most colleges like IITs/NITs). The students in those colleges don’t get any guidance on how to start with open source projects.

That is what we are implementing in our course, “Android for Embedded Systems” where we are going to make students do some real-time projects that are based on Linux / Android open source code.We also have academic projects for B.Tech / M.Tech students that are purely based on Linux / Android open source code.

Embedded Linux Boot Sequence

By Kishore kumar boddu Embedded Linux

In AM335x the ROM code serves as the bootstrap loader, sometimes referred to as the Initial program Loader (IPL) or the Primary Program Loader (PPL) or ROM Program Loader (RPL).

The booting is completed in two consecutive stages by U-Boot binaries.

The binary for the 1st U-Boot stage is referred to as the Secondary Program Loader (SPL) or the MLO.
The binary for the 2nd U-Boot stage is simply referred to as U-Boot. SPL is a non-interactive loader and is a specially built version of U-Boot. It is built concurrently when building U-Boot

Memory Booting: Booting the device by starting code stored on permanent memories like flash-memory or memory cards. This process is usually performed after either device cold or warm reset.
Peripheral Booting: Booting the device by downloading the executable code over a communication interface like UART, USB or Ethernet. This process is intended for flashing a device.

Booting the SPL

The ROM code can load the SPL image from any of the following devices:

Memory booting with MMC
Peripheral booting with UART

1. Memory Booting with MMC

The image should have the Image header. The image header is of length 8 byte which has the load address (Entry point) and the size of the image to be copied. RBL would copy the image, whose size is given by the length field in the image header, from the device and loads into the internal memory address specified in the load address field of Image header.

When using memory boot a header needs to be attached to the SPL binary indicating the load address and the size of the image. SPI boot additionally requires endian conversion before flashing the image

The ROM Code supports booting from MMC / SD cards in the following conditions:

MMC/SD Cards compliant to the Multimedia Card System Specification and Secure Digital I/O Card Specification of low and high capacities.
MMC/SD cards connected to MMC0 or MMC1.
Support for 3.3/1.8 V on MMC0 and MMC1.
Initial 1-bit MMC Mode, optional 4-bit mode, if device supports it.
Clock Frequency: identification mode: 400 KHz; data transfer mode up to 10 MHz.
File system mode (FAT12/16/32 supported with or without Master Boot Record), image data is read from a booting file.
Raw mode, image data read directly from sectors in the user area.
- In raw mode the booting image can be located at one of the four consecutive locations in the main area offset 0x0 / 0x20000 (128KB) / 0x40000 (256KB) / 0x60000 (384KB).

2. Peripheral Booting with UART

RBL loads the image to the internal memory address 0x402f0400 and executes it. No Image Header present.

When using peripheral boot (UART) there can be no header as the load address is fixed.

The ROM Code supports booting from UART in the following conditions:

UART boot uses UART0.
UART0 is configured to run at 115200 baud, 8-bits, no parity, 1 stop bit and no flow control.
UART boot uses x-modem client protocol to receive the boot image.
Utilities like hyperterm, teraterm, minicom can be used on the PC side to download the boot image to the board.
With x-modem packet size of 1K throughout is roughly about 4KBytes/Sec.
The ROM code will ping the host 10 times in 3s to start x-modem transfer. If host does not respond, UART boot will timeout.
Once the transfer has started, if the host does not send any packet for 3s, UART boot will time out.
If the delay between two consecutive bytes of the same packet is more than 2ms, the host is requested to re-transmit the entire packet again.
Error checking using the CRC-16 support in x-modem. If an error is detected, the host is requested to re-transmit the packet again.

Bootloader Images:

Image Name	Image Size	Image Header	Purpose
spl/u-boot-spl	2.2M	No	The binary of SPL ELF Image.
spl/u-boot-spl.bin	91264 Bytes	No	The second-stage bootloader (a stripped down version of u-boot that fits in SRAM).
spl/u-boot-spl.map	227K	No	contains the information for each symbol.
MLO	91784 Bytes	Yes, GP Header	spl/u-boot-spl.bin with a GP image header prepended to it.
U-boot.bin	474K	No	is the binary compiled U-Boot bootloader
u-boot.map	674K	No	contains the memory map for each symbol
U-boot.img	474K	Yes. GP header	contains u-boot.bin along with an additional header to be used by the boot ROM to determine how and where to load and execute U-Boot.

Setup Embedded C Development Environment

By Kishore kumar boddu Embedded C, RaayanMini

Step 1: Test the Raayanmini board

At Kernel Masters, each board is flash tested with self-diagnostic images thoroughly before delivering.

Once you receive the board it is your responsibility to test the board once again, as per the instructions given in the below video.
If you find any test case failures, immediately send a WhatsApp message and inform to Kernel Masters Admin team about the same. In case we do not receive any such message from you, it will be assumed that the board is working properly.

Without testing the board as per the given instructions, if you flash any other image on the board, Kernel Masters is not responsible for the board anymore. So without doing proper testing, do not load any images onto the board.

Step 2: Install Keil IDE & Board Support Packages

Install the version recommended by Kernel Masters for the current KM OS release.

Download VirtualBox

VirtualBox Extension Pack

Install the Extension Pack that exactly matches your installed VirtualBox version.

Download Extension Pack

Important: Do not mix different VirtualBox and Extension Pack versions. If VirtualBox is version 7.x.x, the Extension Pack should be the same 7.x.x release. A mismatch may affect USB, shared folders, clipboard sharing, display resizing and other guest features.

02 · Installation

Download and Install KM OS in VirtualBox

This is the main installation flow. Keep the downloaded KM OS file, VirtualBox installer and matching Extension Pack ready before starting.

Expected setup time: A compatible system can usually complete the installation and first boot verification within a short practical setup session. Download speed and laptop performance may affect the total time.

03 · Troubleshooting

Common Installation and Post-Installation Problems

This section is written for students who are installing KM OS for the first time. Find the problem closest to what you see, follow the quick fix, and then use the detailed steps below when required.

Before trying fixes: do one change at a time. Avoid random online commands. Note the exact error message, VirtualBox version, Extension Pack version and KM OS version before asking for support.

Quick problem finder

Problem seen by student	Most likely cause	What to do first
VT-x / AMD-V error	Virtualization is disabled in BIOS/UEFI	Enable Intel VT-x or AMD-V/SVM and restart Windows
64-bit guest option is missing	Virtualization disabled or Windows hypervisor conflict	Enable virtualization and review Windows virtualization settings
OVA import fails	Incomplete download, corrupted image or low disk space	Re-download the OVA and confirm free disk space
VM starts but runs very slowly	Low RAM, too many host apps, HDD storage or weak CPU allocation	Close heavy apps, use SSD and allocate resources carefully
No internet inside KM OS	VirtualBox network adapter or host network issue	Check adapter setting and restart the VM
Shared folder is not visible	Guest Additions or folder permission issue	Check shared-folder settings and Guest Additions
USB device is not detected	Extension Pack mismatch or USB not attached to the VM	Install matching Extension Pack and select the USB device from VirtualBox
Screen resize / clipboard stopped	Guest Additions modules are not active after kernel update	Rebuild or reinstall Guest Additions

Detailed fixes for common issues

1. VT-x / AMD-V error or 64-bit option missing

Symptoms: VirtualBox shows a VT-x/AMD-V error, KM OS does not start, or the 64-bit guest option is missing.

Shut down Windows completely and restart the laptop.
Enter BIOS/UEFI setup using the key shown by your laptop manufacturer.
Enable Intel VT-x, Intel Virtualization Technology, AMD-V or SVM Mode.
Save BIOS/UEFI changes and boot into Windows again.
Open VirtualBox and start KM OS.

If the 64-bit option is still missing, Windows hypervisor features may be interfering. Check this with the Kernel Masters support team before making major Windows changes.

2. OVA import fails or import takes too long

Symptoms: import stops midway, the image is not accepted, or VirtualBox reports an appliance import error.

Confirm that the file is fully downloaded and has the expected .ova extension.
Do not import directly from a partially downloaded file or unstable external drive.
Keep sufficient free disk space before importing. VM import needs extra working space during extraction.
Move the OVA file to a simple local path such as D:\KMOS or C:\KMOS.
Restart VirtualBox and try File → Import Appliance again.

If the same error repeats, download the OVA again from the official Kernel Masters source.

3. KM OS starts but runs slowly

Symptoms: slow boot, lagging mouse, terminal delay, browser freezing or long build time.

Close heavy Windows applications before starting the VM.
Use SSD storage wherever possible. Running a VM from HDD can be very slow.
Do not allocate all host RAM to the VM. Windows also needs memory to run smoothly.
Allocate CPU cores carefully. A 4-core laptop should not give all cores to the VM.
Avoid running multiple VMs at the same time on low-RAM systems.
Create a snapshot only after the VM becomes stable and verified.

If performance is still poor, use the lighter KM OS version recommended for low-spec systems.

4. No internet inside KM OS

Symptoms: browser does not open websites, apt update fails, Git clone fails or the network icon shows disconnected.

Confirm that internet works on Windows first.
Shut down KM OS, open VM settings and check whether Network Adapter is enabled.
Use the network mode recommended by Kernel Masters for your course setup.
Start KM OS again and test the browser.
Open terminal and test basic connectivity:

ping -c 4 8.8.8.8
ping -c 4 google.com

If the first command works but the second fails, it may be a DNS issue. Share the output with support.

5. Shared folder is not visible inside KM OS

Symptoms: Windows shared folder is missing, files are not accessible, or permission is denied.

In VirtualBox, open VM settings and confirm that the shared folder is added.
Enable auto-mount if that is part of the Kernel Masters setup.
Start KM OS and check the shared-folder location provided by the trainer.
Confirm that Guest Additions are active.
If permission is denied, the Linux user may need access to the shared-folder group:

groups $USER
sudo usermod -aG vboxsf $USER
sudo reboot

After reboot, check the shared folder again. Do not change random permissions on system folders.

6. USB device is not detected in KM OS

Symptoms: development board, USB-to-serial adapter or storage device is visible in Windows but not inside KM OS.

Install the VirtualBox Extension Pack matching the VirtualBox version.
Shut down KM OS and open VM USB settings.
Enable the USB controller recommended by Kernel Masters.
Start KM OS and connect the USB device.
From the VirtualBox menu, select Devices → USB and attach the required device to the VM.
Inside KM OS, check whether the device is detected:

lsusb
dmesg | tail -30

If Windows captures the device again, disconnect and reconnect it, then attach it from the VirtualBox USB menu.

7. Screen resize, clipboard or drag-and-drop stopped working

Symptoms: full-screen mode does not resize properly, shared clipboard stops, drag-and-drop fails or the display remains fixed after a Linux kernel update.

This usually means VirtualBox Guest Additions kernel modules need to be rebuilt for the currently running Linux kernel.

sudo apt update
sudo apt install --reinstall build-essential dkms linux-headers-$(uname -r)
sudo rcvboxadd setup
sudo reboot

If the issue continues, manually reinstall Guest Additions using the ISO method below.

8. Manually reinstall Guest Additions from ISO

From the running VirtualBox window, select:

Devices → Insert Guest Additions CD Image

Then run inside KM OS:

cd /media/$USER/VBox_GAs_*
sudo sh ./VBoxLinuxAdditions.run
sudo reboot

If the ISO does not mount automatically, use this manual mount method:

sudo mkdir -p /mnt/vbox-guest-additions
sudo mount /dev/cdrom /mnt/vbox-guest-additions
cd /mnt/vbox-guest-additions
sudo sh ./VBoxLinuxAdditions.run
sudo reboot

If installation fails, share the error from this log with support:

/var/log/vboxadd-setup.log

Support tip: When reporting an issue, send the screenshot, exact error message, laptop RAM/CPU details, VirtualBox version, Extension Pack version, KM OS version and the output of uname -r. This helps the trainer identify the problem faster.

04 · Safe Usage

Snapshots, Updates and Recovery

Virtual machines are useful because students can experiment, make mistakes and return to a working state quickly.

When to create snapshots

After first successful installation
After verifying internet and tools
Before kernel updates
Before major package changes
Before risky experiments or projects

Safe update guideline

Do not update KM OS immediately before an important practical session.
Take a snapshot before VirtualBox, Guest Additions or kernel-related changes.
If display, clipboard or shared folders fail after updates, rebuild or reinstall Guest Additions.

Snapshot note: A snapshot helps you return to a previous VM state quickly, but it is not a replacement for a complete backup or exported VM copy.

05 · Alternatives

Native Ubuntu, VMware and Common Questions

KM OS is recommended because it gives students a tested setup. Students with strong Linux administration skills may still choose other paths.

Native Ubuntu

Students may use native Ubuntu if they can install packages, configure tools and maintain compatibility themselves.

VMware

KM OS may be importable in VMware, but Oracle VirtualBox is the officially recommended and tested platform for Kernel Masters practical sessions.

COVID-19 Updates & Career Opportunities

By Kishore kumar boddu Covid-19

1. Some Insights on the current situation of COVID-19

Life is the most precious gift. And the most valuable resource is time. Fortunately all of us have both of them right now. We have plenty of time that we can utilize in a productive way to lead our lives into a brighter future.

We live in a society where the safety of every life is of utmost importance to everyone else. Only we happened to realize it recently. It is a kind of positive change that happened because of COVID-19. However the responsibility to keep ourselves safe from the Pandemic lies in our own hands. We can do so by engaging ourselves in some activities which will help us to move towards a sustainable career by staying indoors safely.

The situation has brought many tragedies, but in a way it has also done some good to the nature and also to our lives. Now all we have to do is to stay safe,keep the good changes, come out of this situation clean & Healthy along with our near & dear ones. While we are doing this, it is also a good chance for us to prepare for a better future.

2. Stay Home. Stay Safe. Do not Panic!

By PANIC, we mean the fear of future. What will be the situation after the lockdown? The Corona Virus Pandemic has affected many developed & Developing countries and it has hit them in a really bad way. The countries will take some time to come out of the financial crisis caused by the present situation and the loses incurred by the companies is also huge. All this negativity is going to hit the job market and we might face some difficulties, which might be called by the dreaded name “RECESSION”.

However, my suggestion is , DO NOT PANIC. Be POSITIVE. Every Crisis brings some opportunities too, we only have to identify and grab on time. Especially there is a lot of scope for Embedded Solutions in health industry right now and in coming future.

Students from the upcoming pass out years must be in a blank state of mind, currently, with absolutely no idea about what is going to happen once they are out. It is not my intention to give some future predictions but we would give some suggestions using which, students will have some direction to think in and to seek guidance from someone at least. We have some suggestions for them to cope with this situation.

3. Career Opportunities

Will the Embedded Industry remain same before and after COVID-19 crisis?
I am a ECE 2019/2020 graduate? What opportunities can I expect after COVID-19 crisis?
How to utilize the lockdown period and get ready for the Industry past COVID-19?

These are some questions that must be running in the heads of the Engineering graduates right now.It is Universal Truth that Right Skill and Hard work will never go waste. Even if the world is at a crisis right now, it has to still run.

There will be companies, Industries and jobs. But the numbers might be slightly less compared to the situation before. But they will never be ZERO. This means there will be more competition, which in turn becomes more demand for the right skillset.

Hiring is not going to stop. But hiring will be based on worth of the candidate, because there will be more number of candidates available per position. So your job as a student during this time will be to increase your WORTH.

The COVID-19 situation has actually opened doors to new possibilities in technologies like Artificial intelligence, Block Chain, Embedded Systems etc.

Right now there is huge requirement for Innovative products to deal with this crisis in a better way, in the Health Industry. For example Ventilators, contact less temperature sensors, COVID-19 patient data tracking systems etc.

There is also requirement for time & cost effective solutions in development countries like India. Which brings in greater opportunities for Open Source Technologies. For example, there is a sudden demand for ventilators due to Corona virus disease spread, but there is not enough supply. As a quick solution, Open Source Ventilator development is one of the ongoing projects.

COVID-19 Will Fuel the Next Wave of Innovation

Blended Learning Mode – Advantages

By Kishore kumar boddu Embedded System

Kernel Masters offers a Blended Learning mode to their students for Embedded Systems courses.

What is a Blended Learning Mode?

Blended Learning mode integrates virtual or recorded and physical classroom modes of teaching. We can make efficient usage of time and resources with the help of technology. This approach is gaining popularity over corporates and universities.

How does it work at Kernel Masters?

In Blended mode, the 6 months fresher course contains:

30% recorded videos
30% classroom sessions
40% lab sessions

Recorded Videos: pre-requisites that are expected to know already, are covered in the course in the form of recorded videos, along with some theoretical sessions.

Recorded videos can be played in the classroom, just like normal sessions.After every recorded session, the instructor will explain the summary of the session and discuss the doubts or important points.

Some videos can be given to be watched at home, before starting a new topic, so that student gains some idea before attending actual class. This will help the student to watch the video multiple times and gain some understanding when the topic is complex.

The videos are recorded while our instructors were teaching in the same classroom environment.

They won’t be available to outsiders, the videos are the proprietary property of Kernel Masters.

Classroom Sessions:

30% of the syllabus is covered in classrooms, physically by the instructor.

LAB Sessions:

Everyday there will be 2 hours of classroom and 6 hours of lab sessions.

For every topic, we have a set of well-designed assignments to make the topic more understandable. The assignments are prepared in such a way that at the end of the day, they get complete understanding of the topic.

The assignments will be discussed in the classroom in following classes, whenever necessary to suggest the best approach to solve it.

Why Blended Learning ?

The entire world is moving towards a smart work life. Through Blended Learning, we are also trying to make smart and efficient usage of the instructor’s time.

The training is a 6 months duration course, with a lot of syllabus to cover. We have to cover pre-requisites and basics also, to bring everyone to the same level before starting the actual syllabus.

In Blended Learning mode, we can save the instructor’s energy, so that he/she gets to spend more time on the actual topics, doubts and on the lab issues instead of spending time on teaching the same theory for every batch. This will ensure a better learning experience for the students.
