One of my interest in this board is to evaluate and experiment with the RockPro64. Is it possible, and how, to disable only the A72, and use on the A53? And I would like to have the A72 disabled from power-on. One evaluation is ARM Trustzone on the board, and as the first step want to evaluate it only with the A53.
Compile your kernel but remove the A72s from the device tree. (After boot you can assign processes to CPU etc etc but ...)
- ROCKPro64 v2.1 2GB, 16Gb eMMC for rootfs, SX8200Pro 512GB NVMe for /home, HDMI video & sound, Bluetooth keyboard & mouse. Arch (6.2 kernel, Openbox desktop) for general purpose daily PC.
- PinePhone Pro Explorer Edition, daily driver, rk2aw & U-boot on SPI, Arch/SXMO & Arch/phosh on eMMC
- PinePhone BraveHeart now v1.2b 3/32Gb, Tow-boot with Arch/SXMO on eMMC
