EdgeV no hdmi output

@BGillissen Which board’s version you used about edge-V ? If you use android and it’s work fine , it means that the EMMC is well.

Not sure to understand your question, you asked for the board revision, or the version of the ubuntu image i burned on it ?

In both cases here they are :

Edge_Ubuntu-lxde-bionic_Linux-4.4_arm64_EMMC_V2019011

Hello @BGillissen

Can you try this image to check this issue?

https://dl.khadas.com/test/Edge_Ubuntu-server-bionic_Linux-4.4_arm64_EMMC_V20190809.img.7z

Same result, io errors started right after 2-3secs after i “scp-ed” the same test.rnd file on board.

No idea if this is related, but i noticed those :

according to that bug report https://github.com/systemd/systemd/issues/5806,
the issue should have been fixed with systemd 237, the one used on the ubuntu server image you asked me to test.

I added “systemd.gpt_auto=0” to the kernel cmdLine as mentioned in the link above, but that had no effect.
