PINN Fix for newer Pi models
I haven’t used PINN in awhile and I had a bit of a face palm moment. When I started using Pi 4 originally, the eeprom was able to detect the board revision and automatically select the correct .dtb file. This functionality was just added to the eeprom for Pi 5 models and isn’t in the main release yet, so for any users with a D0, CM5, Pi 500 you must set “device_tree=XXXX.dtb” in your config.txt for the proper dtb file for your model.
This was causing my CM5 to freeze when I moved the mouse and my eMMC not to be recognized, but after explicitly setting dtb in config.txt all works as it should. I’m using 3.9.3. Hopefully this is helpful to any other users.
I’m using eeprom version from March 10, 2025. The fix for this is already included in the yet to be released next standard version, so this should no longer be necessary on whatever the next eeprom revision is going forward. D0 users will need to use the d0 dtb file.
Huh, I assume you're talking about https://github.com/raspberrypi/rpi-eeprom/commit/7f66ffe483698e788858fe51000217849fa6331f ? It sounds like that's specific to CM5 only?
so this should no longer be necessary on whatever the next eeprom revision is going forward.
It looks like that fix is already in the "latest" rpi-eeprom, but not yet in the "stable" version https://github.com/raspberrypi/rpi-eeprom/blob/master/firmware-2712/release-notes.md You can use https://www.raspberrypi.com/documentation/computers/configuration.html#raspi-config to switch to the "latest" bootloader.
Ah, you’re right. I had heard other were having issues with PINN and I only have a CM5 and an original Pi 5 so can only make assumptions about the D0. I stand corrected. Anyhow, it’s not something I had to do with my CM4 so may be helpful at least to CM5 users.
