Pi 5, ControlBlock and nvme issues?

r3dstar

@mitu I did see that, but it seemed to be more about the power switch, however as the poster said that it worked in the end, but wasn't for me the only thing I couldn't match is using nvme. I'll try just going from the SD card after work and see if it does work, or if it is a GIPO issue.

@petrockblog does state that it is Pi5 compatible which again leads me to the use of a nvme SSD.

Installed on an SD card and unplugged NVMe, but the same results.

I'm just speculating here, but it may be due to the Linux kernel version (6.6) and GPIO related changes on that version. Which kernel version do you have installed ? Installing a fresh RaspiOS should start with Linux kernel version 6.1, but if you updated (via apt) then you'll get version 6.6.

@mitu I didn't update, but the default RaspiOS install for Pi5 is 6.6. Tried to install the legacy BullsEye 6.1 from an image and it doesn't want to run on a Pi5.

Try with an slightly older RaspiOS image that has a 6.1 kernel - https://downloads.raspberrypi.com/raspios_arm64/images/. However, while that might make ControlBlock work, may render the NVME Hat unusable if it needs a recent kernel version.

@mitu OK... this is promising.

I've used 2023-12-11-raspios-bookworm-arm64-lite.img on my SD card and ControlBlock works, so the kernal is absolutely the issue.

Now using disk duplicator to clone the SD to the NVMe which is still recognised.

Taking a bit as the card is 128GB...

Fingers crossed.

r3dstar

OK. Done?

Feel I'm missing something, but the SD card is out and ControlBlock is working with the NVMe?

Now to transfer over my games and my custom interface!

OK, so the changes in the RaspiOS Linux ver 6.6 are breaking the ControlBlock driver. I guess the driver needs some modifications to be compatible with the new GPIO naming/changes introduced in that version, so for now maybe skip the Linux kernel package updates through apt.

r3dstar

One thing I have noticed is that it doesn't seem to like the power going via the ControlBlock even refusing to boot past a certain point, power is going in direct to the Pi 5 at the moment.

Sorry, I have messed up my forum notification settings, but they should be good again now 🤦‍♂️
Sort for this delayed reply!

The ControlBlock driver was updated five months ago for some RPi 5 specifics, but if a new kernel version introduces changes to the device tree, the driver probably needs an update again. I will take a look at this! I will update the test script that comes with driver as well. It is not up to date anymore and not very helpful with the RPi 5.
