[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?
