Rpi4 June 6 bootloader wont boot from usb

Postby ivanich » Fri Jul 09, 2021 9:42 pm

After updating bootloader to the new stable version Tue Jul 6 10:44:53 UTC 2021 (1625568293) my rpi4 wont boot from usb, downgrading to the Thu Apr 29 16:11:25 UTC 2021 (1619712685) fixes the issue. Can anyone confirm this?

I'm not able to try your version, but I have no issues USB booting with newer versions such as 20210716

Looks like I found a reason, I've had an GPT partition table, after converting it to mbr I was able to boot from usb ssd. I guess it's a regression though

Ah, my disk uses MBR so I didn't notice.
Looks like is (or was) issues with SD card GPT booting https://github.com/raspberrypi/firmware/issues/1465

If you have a recent-ish raspberrypi-bootloader that works, maybe you can let them know which commit had regression?
Here's the archlinuxarm PKGBUILD version history

That's actually nothing to do with archlinux packages, so what I did is update bootloader via rpi-eeprom-update utility, which I guess, flashes bootloader into the spi and after that I wasn't able to boot from SSD with gpt partition table. I was lucky that I've had another sdcard with archlinux aarch64 installed, so I simply booted into it, downloaded April 29 bootloader and flashed it via rpi-eeprom-update.
