Pi as developing board for ARM9 board and how to start my project

Former Member

Hello,

 

I'm the new one here. My name is Ulrich in the outside world I'm a communication engineer in Finland. I'm having basic knowledge of Linux from doing school assignments which was always fun. Had also an ubuntu machine ones - unfortunately I had no time to play as much with as I wanted..

 

First I have to say that I'm sorry for asking here and taking your valueable time because I know that there are thousands of people asking for the same advice every day. I'm really willing to study myself, I just would like to have some guideliness for my project since I've no experience with embedded Linux. I read the book "Embedded Linux Development Using Eclipse" which was very good to get some basic information.

 

My project is based on an AT91SAM9G20 processor which should run an Angstrom Linux. The device should work as a fieldbus (KNX) coupler. There is going to be a webserver to see status and control the device. 

The reason why I am asking here, in the Raspberry Pi forum, is that I would like to know if I could use the Raspberry Pi as development board for this project since the final board is not available yet. Of course I couldn't connect it to the KNX but I think this is only a smaller part of the project anyways since I'm going to use ready made libraries there. I would like to know if I could easily transport the code (and knowledge) from Raspberry Pi to the final board. I guess this shouldn't be a problem if I could run the same OS on both of them?.. I have to admit that I'm a little bit confused and overwhelmed with all the different Linux software/plugins/packages etc. available.

Therefore I would appreciate it a lot if I could get some guideliness, or maybe a book recommondation, or maybe somebody could give me a link to similar project -  that would be great.

 

Thank you!

Ulrich

  • Just to be clear, I wasn't suggesting using a BBB as a development environment, necessarily. I was suggesting using it in place of your currently unavailable target hardware.

     

    I'm curious to know which problems with Angstrom on the BBB discouraged you. My impression is that there will always be problems reported when people apply new hardware to their fields of interest. The Raspberry Pi has very similar discussions about getting things to work.

     

    I think you are right, there is no obvious need to modify the Linux kernel for what you are doing. However, if you want to use Angstrom on a Raspberry Pi, then you will need to build it because no off the shelf prebuilt distribution exists (as far as I know). I note that there is a raspberry-pi branch of Angstrom which is a good sign. I note also that their wiki and FAQ page links are broken, which is not.

     

    While I agree with jamodios comment about a host build environment, I still think the BBB is going to be a faster route to (my understanding of) where you want to be.
