Can't Modify U-Boot Environment Variables on Updated Firmware
I'm sorry. The log was completely the same halfway. Have you updated all the files?
- bootparam_sa0.srec - bl2-h3ulcb.srec - cert_header_sa6.srec - bl31-h3ulcb.srec - tee-h3ulcb.srec - u-boot-elf.srec
Yes. One thing that wasn't clear to me was where to actually get those files. I've been using the ones that are found in ~/tmp/deploy/images/h3ulcb/ after building yocto. Assuming that's the correct path, I'm going to try rebuilding yocto in case I messed something up in that process.
One possible indication of what the issue is: I looked through the Renesas Device Manual https://www.renesas.com/en-us/doc/products/rcar/R-Car_StarterKit_Gen3_H3_M3_DEV_Rev.053.pdf to find a solution and found that in the section on booting the addresses the board boots from are slightly different from those on the e-linux wiki (looking at page 238 in particular). I'm a machine learning guy by trade and my architecture knowledge is rather scant comparatively so maybe this is nothing/not what I thought it means.
Yes, /tmp/deploy/images/h3ulcb is correct path. Please refer to the No13 of http://elinux.org/R-Car/Boards/Yocto-Gen3#Building_the_BSP_for_Renesas_H3ULCB.2C_M3ULCB.
All updating methods are described below. http://elinux.org/R-Car/Boards/H3SK#Flashing_firmware Could you try again?
If "u-boot" still doesn't start up please attach the log when flashing the firmware.
Rebuilding the whole thing from scratch worked. Something must have gone wrong in the initial build because the .dtb file sizes between the two builds were off by a few hundred bytes.
