rock 4b+ HDMI issue

[linhz0hz]

I have a rock 4b+ and I used it as an android box for a while. Then today I tried to flash it with latest armbian image (23.8.1) and it does not boot in microSD or when I flash it through USB OTG. I have erased the SPI flash completely and install the correct spi_loader. It also boots properly with Radxa debian image.

Initially I though this is a boot issue, but after checking with a serial cable, it turns out this is a HDMI issue.. After I finish the usual procedure to setup password etc... I got this:

 

 

Now starting desktop environment...
