eabivle-gcc:MPU Opcodes not supported

bastian_schick — Wed, 15 Feb 2017 18:24:41 GMT

Hi,

I use

gcc version 4.9.2 20141030 (Wed Sep 7 17:26:57 MSK 2016 build.sh rev= ELvle) (GCC)

It seems some opcodes are not support. At least those for the MPU:

mpuwe

mpusync

Also mas0 to mas3 are not known (minor problem, could add a #define).

I use these option for an MPC5744P:-mvle -mcpu=e200z4 -mspe2

Maybe I need to add something else?

Cheers

Hello Bastian,

we know about this issue. Workaround is following. Use asm(".long 0xABCDABCD"). Instead of 0xABCDABCD use the opcode of the instruction you want to use.

Hope it helps.

Regards,

Martin
