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.
