Secure boot on Milk V duo 256

[Waldo Alvarez]

Hello:

I am figuring out how to proceed on secure booting the Milk V DUO 256. Likely in this list I can get some help. It is ARM/Risc-V board with an SG2002 SOC. The SOC has OTP memory and some bootrom.

The current distribution uses u-boot and linux buildroot but doesn't do secure boot.

Therefore I am trying to start at the first part. Verify digital dignature of u-boot and have u-boot verify digital signature of the kernel.

Can someone point me here in the right direction no how to proceed.

Regards
