[GitHub] [incubator-nuttx] xiaoxiang781216 commented on pull request #2590: boards/risc-v/k210: Fix arch flag since NuttX don't support FPU

URL: https://github.com/apache/incubator-nuttx/pull/2590#issuecomment-779282532


   We already have the code to save and restore fpu registers for rv32im: 
   https://github.com/apache/incubator-nuttx/blob/master/arch/risc-v/src/rv32im/riscv_fpu.S
   Since the register definition is same(except the register width), it should be easy to enhance 32bit version to support 64bit(part of https://github.com/apache/incubator-nuttx/pull/2822).
