Hi @VinayWolf ,

That is great to hear!

I think your best option is to follow what was done for the existing RISC-V ports. I recommend reviewing these files:

• https://github.com/wolfSSL/wolfBoot/blob/master/docs/Targets.md#sifive-hifive1-risc-v
• https://github.com/wolfSSL/wolfBoot/blob/master/docs/HAL.md
• https://github.com/wolfSSL/wolfBoot/blob/master/hal/hifive1.c
• https://github.com/wolfSSL/wolfBoot/blob/master/arch.mk#L545

Are you interested in contributing these changes upstream? Can you tell us more about your project and where you are located? If you'd like to keep that private just email support at wolfssl dot com.

Thanks, David Garske, wolfSSL
