No post after upgraded to 26.2.0-trunk.62

Hello fellow geeks/nerds,

 

Here still using a Rock Pi 4c on 26.2.0-trunk.44. After upgrading to 26.2.0-trunk.62 the Rockpi just does not come back. No display no network. Wish I could provide more details beside the versions. I've went ahead and froze the kernel updates. If there's a way to maybe pull a log of sorts please let me know and I'll post it.

I'll have to order a USB serial cable based on CH340. Give me a few days and I'll have those logs for you.

Maybe a handful, I have most SBC's equipped with one permanently. And needed for Arduinos etc, you can even power tiny old things like RPI0/1 with it (if you connect red wire to 5V pin as well).

 

In the meantime, you might think about some previous U-Boot and previous kernel. For quite some SBCs, there is trouble when U-Boot is new/mainline/releasecandidate and kernel vendor. I am currently also doing some tests on my NanoPi-R6C (RK3588s) because HDMI is not initialized fast enough (by U-Boot). And with 6.1.115 vendor kernel really choppy mouse updates and green tint, not complete flat green luckily, I can still see icons and mouse.
