Can't Modify U-Boot Environment Variables on Updated Firmware
← Thread:Talk:R-Car/Boards/Yocto-Gen3/Can't Modify U-Boot Environment Variables on Updated Firmware/reply
I'm not sure if the Renesas engineers are watching these pages to handle support requests. I think you would be better served by asking the question on their board mailing list. See http://elinux.org/R-Car#R-Car_Community.
I have done so. It looks like my problem is similar to the "Firmware update hangs" thread below except that I can actually get the firmware update to happen. The update obviously doesn't work though since U-Boot doesn't load when it should.
I have the same h3ulcb board(RTP0RC77951SKBX010SA00) as you. I updated the loader but it started normally.

It seems that you changed something. At first, could you build according to procedure of elinux?
I'm sorry. The log was completely the same halfway. Have you updated all the files?

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.
