Once upon a time, Stefan Wahren <stefan.wahren@xxxxxxxx> said: > do you use the DTB file from 5.14.x or 5.16x? I'm booting with EFI firmware from https://github.com/pftf/RPi4 and using the DTB file from that I guess. The reason I'm booting EFI is: - the Adafruit GPS hat connects to the serial lines, and the standard firmware would see input and stop boot - it looked like I could change that behavior if I booted from an SD card by saving a variable file there - but if I put in an SD card, Fedora wouldn't boot, just got a loop of timeouts So I found that I could put the EFI firmware (and Fedora) on a USB drive. And then it looked like I could only use a config.txt to enable the PPS if I didn't use the kernel dtb. So, what's my best path forward? Can I copy the bcm2711-rpi-4-b.dtb file from the dtb-5.16.11-200.fc35.aarch64 directory to the efi directory (and then just remember to swap back to the EFI-provided file if I boot an older kernel)? Sorry, this is my only Pi, so still learning about this side of things. :) -- Chris Adams <linux@xxxxxxxxxxx> _______________________________________________ arm mailing list -- arm@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to arm-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/arm@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
