Get colored blank screen after booting Raspbian 11 on AML905X-cc board

While booting I get the usual splash screens with the Libre logo and display of files being loaded into the system. But when loading seems to be done all I get is a uniform colored screed. I’m new to Linux and these types of boards so I might be ignoring something obvious to most of you.

Troubleshooting Boot Issues on Libre Computer AML-S905X-CC

Did you look at both of these ? I assume you did extract the compressed Image ??

You should just boot up to a standard Raspbian desktop with the Sunset Wallpaper !

Hi Lain:
I’ve since fixed part of the problem by replacing my power supply with a better one. However, I a different problem now. With Raspbian I can see it booting up but after about 10 seconds of a waterfall of file names the screen goes dark with the blue LED flashing while the Red and Green LEDs are lit. I don’t have this problem with Armbian. I would have liked to use Armbian however I intend to use this board with an Astroberry image for telescope control. I seem to run into this issue either using Win32Disk flash program or the Raspberry loader.

“After about 3 seconds, the bootloader should turn on HDMI and displaying the loading sequence. Certain types of displays with odd resolutions are not supported at this stage and it might not display anything during this step and the next steps. If the Green LED turns green and nothing shows on your screen, please post your screen brand, model, and EDID here.”

Have you a different monitor you could try ?

Just out of interest - After the Le Potato has booted up for a minute or so - Have you tried Ctrl Alt F1 ?

Are you sure that the Astroberry image will work on the Le Potato ?

Hi Iain:
I tried the CTL-ALT-F1 but it had no effect, either when after the screen went dark or before. The Green LED is lit so the board should be booting properly. After the screen goes dark the Red and Green LEDs are continuously lit while the Blue LED Flashes two times every second or so.
Other other people have had other non-RPi boards working with Astroberry. Using Armbian I’ve been able to get the IKOS suite to work but have not been able other programs like PHD guiding or other similar programs to work. I’m not skilled enough to recompile the various other programs to work with the Potato board. I do know people have made Astroberry work with other boards.
Right now I’d like to be able to get the Rasberry Pi suite on this board.

It was a bit of a longshot on the CTR-ALT-F1 and Understood about wanting to get Raspbian working.

We know the board works via your Armbian tests.

We know the Armbian SD card works.

We know the image works correctly, if you follow the instructions, due to all the other people who have installed it successfully.

Indications seem to be that its not a Power issue due to the LED’s & Armbian tests.

I would give it another shot using a fresh image on one of the recommended SD cards ???
