I have an issue with booting from eMMC. Device is MXQ Pro 4K (board MXQ_RK3229_V2.0 2019.07.22, CPU RK3228A)
Boots OK from SD Card (Mulitytool). Flashing latest image Armbian_22.02.0-trunk_Rk322x-box_bullseye_current_5.10.60_minimal.img.xz to eMMC.
After flashing, I'm only able to boot if I power on device with SD card plug in, and quickly remove it as soon as blue led turns off, and red led turns on.
Without SD card plugged in, blue led stays on forever and doesn't boot.
