Compilation Problem for MIPS on VxWorks 6.2
I am using VxWorks 6.2 and GNU Compiler 3.3.2
I have ported the BSP from VxWorks 5.5 and GNU Compiler 2.96.
I am using a MIPS 4KEC processor on target machine.
When I assemble my file sysAlib.s, it gives me an error
Error: opcode not supported on this processor: mips2 (mips2) `cache
so to resolve this I have edited the file
It contains a couple of lines -
CC_ARCH_SPEC += -mips2
AS += -mips2
which I have changed to -
CC_ARCH_SPEC += -march=4kc
AS += -march=4kc
And this works for me.
But this might not be a perfect solution.
Can anybody please let me know, what is the correct way of doing this?
