Hey, @jock! After selecting led-conf7 (R29 MXQ, R2B MXQ, H20) in rk322x-config, the screen was displayed immediately without the need to boot from the SD card. Thank you for helping me install Armbian on my tv box.

I've just found that my tv box has no screen but is shown on the network. Even it can be connected via ssh, and works fine. It's a purpose that doesn't require the screen, but I'm curious as to why the screen doesn't come up.

Unfortunately despite your suggestions it still failed. I'll study some more and come back when I'm free. Thank you for your kindness.

Thank you for answer. I've only tested the Legacy 4.4 image briefly, and baked the latest image for rk322x. If I boot with the SD card (MULTITOOL), press the REBOOT menu, and remove the SD card, then I can boot with the latest image burned into eMMC and use all functions. I'm just curious as to why I have to go through procedures like "SD boot" and "Remove SD after REBOOT" to boot. I still don't know how to check LOG through UART.

This is the MXQ PRO 4K 5G TV BOX with RK322A CPU, 1GB RAM, and 8GB eMMC. I booted MULTITOOL onto the SD card and burned the latest jammy image and Legacy 4.4 image for RK322X. After REBOOT on MULTITOOL, I got a nice ARMBIAN screen and everything was fine. But when I restart it after shutdown, the screen goes blank. It is still possible to boot with MULTITOOL on SD, and from here you can enter ARMBIAN through the REBOOT menu, but booting with only eMMC fails as the monitor screen goes into sleep mode. What's the problem?
