That worked, thank you.

Hi, I've downloaded the 4.19 kernel source from https://github.com/TinkerBoard2/kernel/tree/tinker_board_2-debian_10-2.1.6 and built with: make ARCH=arm64 tinker_board_2_defconfig make ARCH=arm64 rk3399-tinker_board_2.img -j8 Copied boot.img to SD card with dd if=boot.img of=/dev/mmcblk0p4 status=progress && sync Rebooted: the system is stuck at "Waiting for root device /dev/mmcblk0p9" What I did wrong? Thank you
