Subject: RISC-V crt0.S
Date: Sat, 11 Jun 2022 18:56:27 +0300	[thread overview]
Message-ID: <D7505FBD-2E81-41CD-B915-396E3E990343@livius.net> (raw)

Hi,

I tried to use the RISC-V semihosting configuration, and I noticed that crt0.S is very simple, and does not process the command line arguments, as per Arm semihosting specs.

Then I tried to override _startup() with my own version, and I noticed that the function is not defined as weak, so I had to name mine differently, and call it from the reset handler.


It would be great to bring the RISC-V semihosting crt0.S to the same functionality level of Arm semihosting.


Regards,

Liviu
