[yocto] Kernel Build error

[Harinath maddelal]

Hi,


Kernel Version is 3.10.60 & our platform is mips32.

For GCC I haven't made any changes. I have used the default GCC from yocto. Looks like by default it is using 5.3.0 version.


Can we specify our GCC in the YOCTO?


Thanks and Regards,
Harinath

Can you please tell me what could be the issue? We have used mips32r2 in our machine file but if the error log is observed where it says "Error: opcode not supported on this processor: mips3 (mips3) `sdc1 $f6,272+48($4)".


Can you please help me resolve this issue. Thanks in Advance


Thanks and Regards,
Harinath
