Hi Matt,
The cross-build gcc is shared by different PPC architecture, including e500v2,
e500mc, e5500 and e6500, those -m parameters are necessary for cross-compiling
of specific core type. The following manual may be helpful to understand of
Yocto SDK.
Hi Zhenhua,
Thank you for the answer.
So the -m options generated by Yocto SDK below is for e500v2, correct? If not,
could you please explain?
CC="powerpc-poky-linux-gnuspe-gcc -m32 -mcpu=8548 -mabi=spe -mspe
-mfloat-gprs=double --sysroot=$SDKTARGETSYSROOT"
Thank you,
Matt
