CM4 not being recognized #187

Closed Roycinger closed 9 months ago

Roycinger commented 9 months ago

Describe the bug

After starting either rpiboot.exe or rpi-mass-storage-gadget.bat, the CM4 is not being recognized and gets stuck, see screenshot: image

I'm using a newly acquired CM4 (I guess latest revision, can't confirm), and a Bigtreetech Manta M4P as carrier. The M4P get set up with its DIP switches 3 and 4 to ON (like described in the manual here.

Using alternative cables and ports didn't yield a different result.

Steps to reproduce the behaviour

Set up carrier as described, attached USB-C to carrier

Device(s)

Raspberry Pi CM4

Compute Module IO board.

Bigtreetech Manta M4P V2.1

Did you follow the manufacturer's instructions? Have you raised a support ticket with the manufacturer?

Yes, I followed the instructions as per the manual. I opened a ticket with the manufacturer in parallel

It would be worth following the troubleshooting guide https://github.com/raspberrypi/usbboot#troubleshooting

pelwell commented 9 months ago

Including (from https://bigtreetech.github.io/docs/Software%20Installation.html#cm4-emmc-version):

in order to avoid problems caused by the insufficient USB power supply of the computer, it is best to use an external 24V power supply to power the motherboard

?

Roycinger commented 9 months ago

I'll go through the Troubleshooting guide. I did attach a 24V PSU aswell, just didn't mention that in my initial post

pelwell commented 9 months ago

Note that the sequencing is important, at least on a CM4IO board - the USB cable must be connected from the host to the CM4IO before the power is applied.

timg236 commented 9 months ago

adding to the comment from @pelwell if the logs are at this stage then it looks like the host has not seen the USB descriptor from the 2711 chip-rom. This could be caused by wrong sequencing, or something else which prevented the ROM from seeing the nRPIBOOT GPIO.

Unfortunately, there's no progress at this point. Bigtreetech support did answer but didn't seem to understand the problem. I tried once again by removing the Type-C Power Jumper and attaching direct 24V to the board (as per the documentation on page 10), same result, CM4 doesn't get recognized by the PC while rpi-mass-storage-gadget.bat is running. I also paid attention to the correct sequence as @pelwell described.

Any chance you can test the board with rpiboot on a Linux System (eg. live System or rpi)? I've witnessed more than once strange issues where the usb does not work on windows but without any issue on Linux.

I have an old macbook around, I will try it with this one after work

Thanks for all your help guys. The issue seemed to be my Windows machine. I installed usbboot on a Mac device and the CM4 / Manta was recognized immediately. I was able to flash the image and the device is available over Wifi now. Still strange that Windows didn't see the CM4 but I can work with that.
