RISCV inline assembly code

[Nhon Quach]

Hi, all,

I am writing C code, but need to point the a0 and a1 registers in the CPU to some data structures and do a few other things (such as making a call, etc.). Is there any reference material I can read up on? I found some generic asm volatile stuff for putting inline assembly code, but they are x86 specific. Is there a RISCV one somewhere?

Would appreciate your help asap. I am stuck :).

Thanks,

Nhon

Any use?

I was using this manual:

http://www.ethernut.de/en/documents/arm-inline-asm.html

It works well on my riscv experiments.
