Hi, Rafael,
Thank you very much for your clear explaination.
I compiled a hello.c by command-line instruction "arm-none-linux-gnueabi-gcc hello.c<enter>". And I succeeded in running the resulting executable on the DM8168 EVM target.
Later, I plugged-in the Codesourcery.into Eclipse. Creat a "hello world" C/C++ project in CCS 5.4. Compiled it once again. But stuck at the compiling error: bad value (cortex-m4) for -mcpu= switch
I do not know how to solve it.
Best Regargs,
Michael
