i just bought development kit at91rm9200, and now i'm quite disappointed, because there is no development software included..

does anybody have me some hints how to start developing my own mikrocontroller software? i'm working on a windows machine, but i also have the possibility to work under linux. but in both cases i don't know how to proceed..

i would be very glad to get some ideas!!

cheers

Hi greenhorn,
there is a GNU toolchain (compiler, linker, assembler, debuger) available which you can use to program this controller. This controller has some very nice download possibilities, including the serial device (x- or y-modem). Perhaps you can use this for your purpose.

To get information how to start, you can take a look of the free available bootloaders. A very important thing, is to understand "How the contoller and its architecture works". Use the "ARM9 technical reference maual" (located for instance at http://www.atmel.com/dyn/products/other ... ily_id=605) for this.

Before you can start test your code, you need a possibility to download code to your board. Then start programing smal things - LED switching for instance and so on.



Hope this helps,
Edi

thanks for your reply!

i heard about this gnu toolchain, but i didn't get it out, how i can install this and use it.

do you now a good installation instruction?or can you give me some hint?

Hi greenhorn,
if you want to use Windows there are two possibilities for the toolchain (arm-elf-):
1. native windows version - http://h-storm.tantos.homedns.org/gcc_arm.htm
2. cygwin version (i have build my own version based on gcc 3.3.2)

If you use Linux there are several prebuild versions available.
To get information about the toolchain try google with the following strings:

site:lists.arm.linux.org.uk toolchain

or go to

http://lists.arm.linux.org.uk/mailman/l ... -toolchain

Best regards,
Edi

Hi,
here i am again.
There is also a gnu cross compiler (gcc 2.95) on the new Atmel CD ROM. It seams to be a linux based toolchain.
It is located below the Linux-ARM9 directory.

Edi
