Re: rpi4b main-n245392-8423f5d4c12 won't boot due to microsd timeout (13.0-RC2 not good for RPi* firmware)

Unfortunately, FreeBSD-13.0-RC2-arm64-aarch64-RPI.img
still has older RPi* firmware that does not work:

After initalizing a microsd card from:

FreeBSD-13.0-RC2-arm64-aarch64-RPI.img

and mounting it on /mnt , I see:

# strings /mnt/start4.elf | grep VC_BUILD_ID_
VC_BUILD_ID_USER: dom
VC_BUILD_ID_TIME: 22:19:57
VC_BUILD_ID_VARIANT: start
VC_BUILD_ID_TIME: Jan 27 2021
VC_BUILD_ID_BRANCH: bcm2711_2
VC_BUILD_ID_HOSTNAME: buildbot
VC_BUILD_ID_PLATFORM: raspberrypi_linux
VC_BUILD_ID_VERSION: 99d9a48302e4553cff3688692bb7e9ac760a03fa (clean)


By contrast doing similarly with:

FreeBSD-14.0-CURRENT-arm64-aarch64-RPI-20210311-15565e0a217-257277.img

and looking a the /mnt , I see:

# strings /mnt/start4.elf | grep VC_BUILD_ID_
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)


The Feb 25 2021 firmware works on various RPI4B's
and the Jan 27 2021 does not, for example.

This means that 13.0-RC2 is not an appropriate
basis for the msdos file system content.

(I've not checked u-boot .)

Replacing the older with a copy of the newer would
be an option.
