Linux enviroment?

I am new to Linux Arm embedded system. I’d like to obtain the Linux development kit for A9M24XX modules from Digi International, to save efforts for setting up ARM enviroment. Can anyone recommend a Linux base system such as Fedora, Debian, Ubuntu or other distros would work for developing these modules. I have had bad experiences in installing and setting up a Linux system with ARM patches for Samsung S3C2410A. Thanks for all your help.

The cross compilation should work with any linux distribution.
However Digi Embedded Linux for CC9M24xx (the new name for A9M24xx) is: “LxNETES-3.2” (status: 08/2007). It was mainly tested under Debian and the manual refers to Debian style setup, e.g. to setup tftpserver, nfsserver, …
The manual does not match e.g. Fedora. Although customers succeeded using Fedora, we can’t help much with setting up under Fedora.

When I got my Debian up running. Then will you to show me how I can write the code in LxNETTES 3.2 enviroment to access I2C and UARTs. Thanks,3167#9907
