I bought a raspberrypi 5 compute module development kit, part number KIT-27252. I installed Ubuntu 24.04 on it using raspberry pi imager and the instructions on the raspberry pi website (with rpiboot). It worked for a few minutes but then eventually the lights on the front faded. Now when I connect power, it won’t light up at all. And it won’t boot.
So I ordered a new I/O board and compute module, thinking one of those two was bad. Got the new ones. They power on just fine and I can install images with raspberry pi imager. But when I boot the images (tried Rasbian and Ubuntu), it just shows the splash for about 10 minutes then goes to an initramfs busybox shell - as if it can’t read from the emmc?
I’m using the 27W power supply provided with the development kit. Any ideas why these boards don’t work?
It sounds like you might be dealing with either a power issue or an eMMC-related problem. Since the new board powers on but gets stuck in the initramfs shell, it could indicate that the OS isn’t properly reading the storage. You might want to try re-imaging the eMMC with a fresh install and verifying the image checksum before flashing.
Also, ensure that the boot mode switches on the I/O board are set correctly. If the issue persists, try booting from a USB drive instead of eMMC to see if the problem is storage-related.
Oh I can boot to a USB drive? How do I do that? I’d actually prefer to boot to an nvme drive if possible. I have one here to use. I searched a little about the topic and it seems I need to boot to emmc just to set the boot order in eeprom? Is it possible to configure nvme boot if the emmc is not working?
I did try reimaging the emmc several times but was not able to boot to emmc
