   Hi, guys:

   I am looking for a x86 based EVB which works with uClinux 2.038.

   Any suggestion?

  Thanks

  Simon

Hi,

So now which target should one uses for (cross) compiling
a) - uclinux kernel ?
b) - uclinux apps ?

Does TARGET = arm-uclinux will do for both?
Currently i have xgcc with TARGET = arm-uclinux-elf, I also used a
TARGET=arm-elf sometime.

What are now the main differences between those 3 TARGETs ?

Thanks
