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.
I'm no expert of secure boot area.. but you can search first, there are quite a lot docs/articles about secure boot of uboot/linux
for the initial bootchain: from bootrom to bootloader, there is indeed secure boot feature which documented in vendor datasheet, see chapter 14
