I took a different path of setting up a stable/13 based media, based on my own build context but upgrading a 13.1-RELEASE starting point. This stable/13 variant boots the RPi4B's just fine via the USB3 media that 13.1-RELEASE failed to boot with. I'm not sure what the differences that matter are. For reference for the working stable/13 context and other content involved: # strings -a /boot/efi/start4.elf | grep VC_BUILD_ID_=20 VC_BUILD_ID_USER: dom VC_BUILD_ID_TIME: 12:10:40 VC_BUILD_ID_VARIANT: start VC_BUILD_ID_TIME: Feb 25 2021 VC_BUILD_ID_BRANCH: bcm2711_2 VC_BUILD_ID_HOSTNAME: buildbot VC_BUILD_ID_PLATFORM: raspberrypi_linux VC_BUILD_ID_VERSION: 564e5f9b852b23a330b1764bcf0b2d022a20afd0 (clean) (/boot/efi/armstub8-gic.bin does not have very useful version-string information.) # strings -a /boot/efi/u-boot.bin | grep 'U-Boot 20' U-Boot 2021.07 (May 12 2022 - 07:00:33 +0000) Note: To my knowledge, the RPi* firmware, armstub8-gic.bin file, and u-boot.bin file above are all as they were for 13.1-RELEASE's image, other that for 13.1-RELEASE I had also tried adding /boot/efi/timeout and I've left that in place since then and I've added my usual /boot/efi/config.txt material (that had also not made a difference for 13.1-RELEASE).
