I got the board RCar H3 v1.1 (RTP0RC7795SKBX0010SA00) and created a AGL(Automotive Grade Linux) agl-image-weston version 10.0.3 jellyfish, but the display is not showing correctly the pictures and is not in accordance to the u-boot variables.
I.E. I have the u-boot bootargs as "... vmalloc=512M video=HDMI-A-1:1920x1080@60..." with the load_dtb var loading the r8a7795-es1-h3ulcb.dtb, and the display says that the image is not in a correct format. I changed to 1280x720@60 and the display outputs the correct resolution but at 25Hz. I changed dtb to the one for the board v2.0+ and the display outputs at double the refresh rate that it's set on the variables, with high system instability.
What could be the root of the problem? As far as I know AGL jellyfish uses yocto project 3.1 which is still compatible with the H3 v1.1.
Your board is very old and no longer supported.

Please consider purchasing a new R-Car…
In my remember, DD (UCB4.0) or EE(UCB5.0x) might be launch on H3 v1.1 from the version table. But sorry I don't know that it will success, because H3 v1.1 is not official support board…
Please consider purchasing a new R-Car H3 v3.0 SK board(RTP0RC77951SKBX010SA03).
Thank you for the reply.
Do you know what's the last AGL version with support for the 1.1 board?
In my remember, DD (UCB4.0) or EE(UCB5.0x) might be launch on H3 v1.1 from the version table. But sorry I don't know that it will success, because H3 v1.1 is not official support board on AGL that time. And more, I guess AGL DD/EE can be build or not.. Because AGL DD/EE and related Yocto are EOL
Yocto v3.4 or later don't support H3 v1.1 Starter Kit (RTP0RC7795SKBX0010SA00).
