Hi to all
If you already have the uC, you have to search into uCLinux distribution
HW compatibility (with the hope to find your uC in the list).
But if you want to start to learn something about uCLinux , Motorola
(now Freescale h**p://www.freescale.com) sell a development board
for the Coldfire series 5xxx ready to install a version of uCLinux.
Pay attention at the drivers for the peripherals, two years ago a friend of mine
have lost a lot of time to make USB working.
Good Luck!!!! You need it!!!
