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.

[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.
