Renesas RZ/G2LC boot from USB, I am following this link https://renesas.info/wiki/RZ-G/RZ-G2L_Flash_Programming .
In the step 0(Environment setup) : As soon as I try to install package libubootenv in my yocto (3.1.5 dunfell), Multiple versions of u-boot are due to be built(u-boot_2020.10.bb and u-boot_2020.01.bb).
Except that all other steps are clear to me except how to make USB thumb drive with Image .dtb rootfs and initram fs. Also I don't know how to perform step 1 with windows teraterm macro. I have tried so far
1)Image and .dtb copied into RZ_FAT(partition in USB stick)
2) copy core-image-minimal-smarc-rzg2l-mod.cpio.gz.u-boot into RZ_ext(another USB partition)
3) Followed step -1(programming ATF) using linux script
After
following these steps I could boot up my device by changing environment
variables, but no file system updated. Also I couldn't see the logs of
custom initrd script after booting up.
