LiteOS will not compile for petitbateau variant #71

Closed AEW2015 closed 1 year ago

AEW2015 commented 2 years ago

I can compile LiteOS for the quark variant just fine, but when I try petitbateau variant, I get this error:

I have the same issue, I think you need to add -march=rv32imac -mabi=ilp32 to LDFLAGS, but when I do that I get the error:

This is being built on MacOS but I get the same error when I replicate it on Linux.

Fixed (now LiteX uses extended RiscV extension names, which confuses the linker, fixed makefile.inc to remove them in the flag passed to the linker)
