I’m modifying U-Boot to implement some custom boot logic for Rock Pi 4b. What I would like to do is to use (customized) U-Boot in eMMC to boot into Android image installed on NVMe drive. I would like to know which configuration was used to build
uboot-trust-spi.img in this link.
I saw this comment that says
rk3399-pie-gms-express-baseline branch from
radxa/u-boot repository was used to build the image, but it doesn’t specify the commit ID and the exact configuration. I tried
rock-pi-4b-rk3399_defconfig, but U-Boot built from that configuration was not able to boot Android from NVMe. Can I get the information on how to build that
