I'm unable to reproduce this on either the 19.10.1 image, or the current Focal dailies.
On the very first boot the message "Loading environment from FAT... *** Warning - bad CRC, using default environment" does appear but that's because these images have no environment to load from the FAT boot partition. However, interrupting u-boot and entering the commands you've specified does produce a valid uboot.env on the partition and subsequent boots show the message "Loading environment from FAT... OK", and don't show any interruption prompt. Can you confirm a uboot.env exists in /boot/firmware and is 131072 bytes large? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870981 Title: u-boot environment modification does not work raspberry 4 with eoan To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/u-boot/+bug/1870981/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
