The highlighted comment was created in this revision.

Currently, two CA57s are running in StarterKitPro. Could you tell me how to boot with six cores total of two CA57s and four CA53s?

To try it here, CA57CA53BOOT = "1" was added to local.conf.

    Hi

    This is quoted from the AGL mailing list.

    [agl-discussions] A53 CPU on renesas board? 2017/05/10 (水) 18:01

    > Out of curiosity, A53 cores on R-Car board (in additoin to A57 cores) could also be enabled for AGL system easily (for accelaration), or rather to be used to host different OSs?

    Hello,
    In order to enable the A53 CPU's on the r-car boards, you need to add this line in
    meta-rcar/meta-rcar-gen3/recipes-bsp/arm-trusted-firmware/arm-trusted-firmware_git.bb:
    export PSCI_DISABLE_BIGLITTLE_IN_CA57BOOT="0"
    and rebuild and reflash the firmware as explained in http://elinux.org/R-Car/Boards/M3SK.
    

    Is this useful for you?

      Thank you very much.
      I solved it.
