[PATCH] riscv: Makefile: make it possible to use riscv64 compiler

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



At the moment riscv64 toolchain can't be used to build
barebox for riscv32, e.g.

  barebox$ make erizo_generic_defconfig
  ...
  barebox$ make
  ...
  riscv64-zephyr-elf-ld:
  common/memory.o: ABI is incompatible with that of the selected
  emulation:
    target emulation `elf32-littleriscv' does not match `elf64-littleriscv'

The patch fixes the problem by explicit riscv32 target options selection.
