I have a Pi 4B 2G with a Uputronics u-blox GPS HAT, which puts the GPS module serial data on the first serial port lines. The problem is that U-Boot stops boot on serial input, and the GPS module is always sending data when it has a fix. I put Fedora 36 Server on an SD card, and set the U-Boot stdin, stdout, and stderr environment variables to exclude serial (which wrote uboot.env), and that worked. Then I unplugged the keyboard... and it appeared to automatically re-add the serial and stop boot. I have an extra Logitech unifying receiver I could leave plugged in (which seems to work), but that needlessly uses up a USB port. Is there a way to tell U-Boot "no really, ignore input from the serial port"? -- 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, report it: https://pagure.io/fedora-infrastructure/new_issue
