Here is the BeagleV Ahead: https://git.beagleboard.org/beaglev-ahead/beaglev-ahead-u-boot/-/blob/beaglev-v2020.01-1.1.2/include/configs/light-c910.h#L361 It might give some clues as to want commands to try. >From the lpi4a config: https://github.com/revyos/thead-u-boot/blob/09e2c3f93f1a64c10ca51d9b9c0c22fbc0947c43/configs/light_lpi4a_defconfig It looks like it sets: CONFIG_TARGET_LIGHT_FM_C910_LPI4A=y And that corresponds to: https://github.com/revyos/thead-u-boot/blob/09e2c3f93f1a64c10ca51d9b9c0c22fbc0947c43/include/configs/light-c910.h#L425 Anyways, I finally got my Lichee Pi 4a out of the box, and I am going to try it out too. -Drew
