r-car M3 show different rev version and model after u-boot flash on board.

I want to updated u-boot from 2018 to 2020.10  and I did the following steps.

 bblayers.conf :         

POKY_BBLAYERS_CONF_VERSION = "2"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

BBLAYERS ?= " \
${TOPDIR}/../poky/meta \
${TOPDIR}/../poky/meta-poky \
${TOPDIR}/../poky/meta-yocto-bsp \
${TOPDIR}/../meta-renesas/meta-rcar-gen3 \
${TOPDIR}/../meta-openembedded/meta-python \
${TOPDIR}/../meta-openembedded/meta-oe \
/home/hiams_sv/workspace/renesas/yocto_5_1_0/m3ulcb/meta-rcar/meta-rcar-gen3-adas \"

Add soc family in local.conf 

# SOC family changes
SOC_FAMILY = "r8a7796"

after that I build ATF, optee and u-boot by using following command

bitbake u-boot

bitbake arm-trusted-firmware

bitbake optee-os

After that flash all required files on board by using the following steps on.

https://elinux.org/R-Car/Boards/M3SK#Flashing_firmware

after successfully flash all file I started the u-boot

it showing  R8A7796 rev3.0 and model m3ulcb based on r8a77960. but as per my understanding for this board it should be... 'r8a77961' . this is also mention at elinux page table. see the last option in below table that I have.

Why at one place it showing r8a77960  as per my board M3SK with SOC version 3 it should be r8a77961.

  • Hi Kalls,

    I confirmed the same phenomenon with M3v3 SK (and H3v3 SK) in Yocto v510.

    Why at one place it showing r8a77960  as per my board M3SK with SOC version 3 it should be r8a77961.

    As you pointed out, "r8a77961" is correct.
    However, the current BSP(u-boot) is displayed as "r8a77960".
    It will be fixed in the future.

    Thank you for pointing it out.
