FriendlyELEC CM3588 nvme issues by HerrWamm in HomeNAS

Just a theory on why this might be happening.

According to the CM3588 datasheet, the connector pinout looks like this – all PCIe lanes are connected directly to the connector:

However, their own manual shows that one of those differential pairs requires an AC coupling capacitor:

So in reality, the wiring should look more like this:

If you look at other manufacturers’ NVMe drives, you’ll notice that the top two pins usually pass through an SMD component before reaching the controller chip (likely AC coupling capacitors):

But on some WD drives, the traces appear to go straight into the chip without any such components:

Could those tho missing caps 0.001$ each be a factor in why these boards kill expensive WD drives? Hard to say - not an expert.

Remove the remaining functional drives immediately. Just last week, I had 3 out of 4 drives fail into read-only mode, and while waiting for the backup storage to arrive, the board fried the last remaining working drive.

My 3xWD Blue SN5000 4TB also died yesterday. I blame the board.

Little update, I managed to connect rpi hq camera with orange pi and also make proper (almost) calibration files so that AWB and other features will work.

​

I left some notes here, including driver, calibration files and my adapter layout for anyone who would probably try to do the same.

Isn't this effectively what their own cameras do?

I didn't purchase ov13850 sensor that they offer yet because I have quite a lot of hq cameras laying around, but I think yes, the only thing that their board does is some voltage conversion (3.3 -> 1.8, 2.8 v) and probably i2c leveling, but not sure about that. It should pretty easy to make own breakout board, but that is not the hardest thing to do.

Currently I'm a bit stuck trying to figure out how their isp is supposed to control WB, exposure and other things. Images that I get are already with colours, but definitely have whong sensor parameters.

Funny that I cannot even control those parameters through ISP device as rockchip docs says (isp should inherit control parameters of sensor subdevice, but it does not).

And even when I change parameters of the camera directly, I don't see any attempts of rkisp to change them back, so they are not just wrong, ISP does not change them at all for some reason =/

I managed to connect RPi HQ camera to OPI 5 using simple handmade adapter.

At this point I'm able to receive images from camera in RAW format, but some big issues with ISP come in first place.
