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.

Ok, I got the serial output working. Oddly everything worked and the unit booted. 😕

 

So I go and put the Radxa Penta SATA HAT and boom back to the same issue. The HAT appears to be causing an issue. Activity light is on but in a continuous double blink. The NIC is also showing activity but I can not access or ping. Switch shows a link but no data. Sucks because of the Penta HAT, I am not able to connect the serial to USB cable. The HAT is covering the entire GPIO.

Thought to myself. Ok, let's revert back to an older release (Bookworm). It has the same issue. It's not until I get to Bullseye that it works. Has me thinking. Am I that few who purchased the Rock Pi 4C non plus with their Penta SATA HAT?

Sounds a bit like with My ROCK3A. Bought it last yer and with a SATA breakout board. That breakout board was a newer HW version with a but flatter and simpler (and cheaper of course) SATA connector, such that I could get a SATA cable connected as the MIPI DSI conector was in the way, just slightly too high. So for the 3 euros that it costed I thought, time to warm up the soldering iron and lift it a bit so a SATA cable fits. Radxa apologized and I think the idea was that I would get some new SATA thingy or so for free. Yeah right, trust is gone. That proved a second time as they did not take any further initiative. For example how do they think they can reach me (being at the at the other side of the world). Also now that combination is is just removed from the products page. Indeed they sell now own ASM1166 M.2 M-key modules, of course at a higher price that the generic ones on Aliexpress. No surprise form a Chinese a company, they just throw new boards on the market and hope someone will be their guinea-pig.

 

Also your ROCK4C (non-plus) is not listed anymore. Also note it has no PCIE, so my guess is it uses some USB3 connection. I personally avoid it like a plague. Maybe it can save you in this case, maybe try to get a schematics of the PCB, then the whole thing might work with the HAT off and just GND+5V with own soldering/wiring. Else sell it befor it is too late. That is what  also have advised a RPi5 + SATA HAT user who had trouble. As separate components, loss it not too big maybe. My ROCK3A+breakout board was 40 euros, great for replacing old PC for 1 SATA HDD. 

 

That those HATs are covering all GPIO, I know, that is why I never will buy a HAT again, also not a Raspberry I think who 'invented' it. I soldered extra wires on top. In your case I would solder the USB console cable on the underside, drop of hotglue and done. Faster than I can write this message. Or else look for a PUKE (Peripheral Under Kernel Environment module that is meant for debugging low-level U-Boot and kernel issues).
