Low Level System Build - No HDMI Output

Cubie Series A5E
1

Hi!

My goal is to build a system image for Cubie A5E from source to integrate e.g. a different DSI display. I started to build a system image as describe here: https://docs.radxa.com/en/cubie/a5e/low-level-dev/build. The build succeeded and I was able to write it to a SD-Card. But the system was not booting. I had not output from the serial console.

My next step was to test the board, cables and hdmi display (Full HD). I took one of the downloadable images (a527_linux_cubie_a5e_uart0_beta_20250211.img) and it worked. I got output from the serial console and later on the HDMI display. Everything was working.

Then I tried to build the system image as described here: https://linux-sunxi.org/Radxa_Cubie_A5E. The build succeeded and I was able to write it to a SD-Card. The system was able to boot and I got output on the serial console. The systems starts up to the login prompt but the HDMI display stayed dark - no output.

Has anyone an idea what went wrong?

Attached the startup log.

Let’s go back to the previous solution of compiling with RSDK. The images built with TinaSDK may have some issues, as this is not the SDK we primarily maintain.

Please check the status of the image you built using RSDK and describe the steps you took during the process.
