Ubuntu Natty on Pandaboard: Native Build Steps

Natty on Pandaboard

 
 
 
 
 
 
 
 
 
 

When I decided to make changes in the Ubuntu Natty Linux kernel (Version 2.6.38) for Pandaboard on my laptop. I thought, it would be a straight forward affair to build it and flash the generated image onto the Pandaboard’s SD card and see it running smoothly…

That time did not know that I would need to change my plan and search the Internet for right build instructions, which eventually I could not find.

Later I decided to go for another option, native build the Kernel on the Pandaboard itself..

Useful Linux Commands: Part III

Linux Tools

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

This post continues from Useful Linux Commands: Part I , Useful Linux Commands: Part I and list the commands which I found special in embedded Linux environment.

While working on Pandaboard related project, which boots using a SD card, I needed to backup the SD card before I experimented with boot sequences, display resolution, etc. I knew direct cpying the two partitions (FAT32 and linux partition) to backup may not be a 100% backup.

kernel.org is down!

kernel.org Down for maintenance

kernel.org Down for maintenance

Earlier this month, a number of servers in the kernel.org infrastructure were compromised. We discovered this August 28th. While we currently believe that the source code repositories were unaffected, we are in the process of verifying this and taking steps to enhance security across the kernel.org infrastructure.

What happened?

This post will continue from Useful Linux Commands: Part I and list the commands which I found useful in Linux environment.

Must mention the greatness of the Linux command line tools especially its various thoughtful switches/options. It makes the life of developers very easy and saves a lot of time. More importantly it helps people like me to continue to be lazy (did I say smart!?!)..

Linux Driver Development How-to: Get Started Live!

SDIO

 
 
 
 
 
 
 

Ever wanted to get into the world of Linux Driver Development and started with LDD book:

  1. Then looked at the ‘Hello World’ driver module, finished it successfully. Later after introspection found it was too easy and did not learn much ‘critical’!
  2. After reading a few pages, eventually realized its not for you and left the journey?

If this is the case, go ahead and read further..

Well, its not that easy or that difficult. However ‘careful’ is the word one should always remember, as any small misadventure can ruin the system. Just follow this:

  • Take a deep breath
  • Just understand what you are doing
  • Leave the mentality of user space development, outside the room
  • Follow the best practices in the kernel space development

Here, I’m going to take a live module from Linux kernel space as an example to get started and show how to tweak and learn more in the process of ‘Linux Driver Development’!

Quickly I could think of following:
