I need little_endian mode in CodeWarrior

[Gabriel]

Hi, is it posible to use Codewarrior in LITTLE_ENDIAN mode, or it olny works in BIG_ENDIAN mode?

I can tell you that for bi-endian PowerPC MCUs, CodeWarrior does *not* produce good code in little-endian mode. You can get the processor to enter LE mode and get basic code to run but memory mapped register accesses are screwed up. According to Freescale, LE support has been officially dropped for PPC processors... Don't get me started on the absurdity of this...

What target MCU/MPU you are talking about? The wast majority of Freescale (former Motorola) MCU's and MPU's are big endian and Codewarrior just follows that. Are you targeting ARM core, that (I heard something) can be switched between low and big endianess? I don't know if it's supported by CW for ARM. Even if it was supported, I would choose the mode that matches the endianess of 16 and 32-bit wide peripherals.
