Greetings!
I'm trying to install FreeBSD on a Raspberry Pi 4B w/ UEFI.
I've done the following:
* update the RPi4 firmware to support USb boot
* format a USB drive as follows
$ gpart show
=> 63 468862065 da0 MBR (224G)
63 32768 1 efi (16M)
32831 468829297 2 freebsd (224G)
=> 0 468829297 da0s2 BSD (224G)
0 16777216 2 freebsd-swap (8.0G)
16777216 452052081 1 freebsd-zfs (216G)
* make a dos file system for the efi partition and copy the uefi files (most
recent version) in there
* make a ZFS pool and file systems as appropriate for a boot environment
* build CURRENT from source with D25201 manually applied (the other patches
have apparently already been merged) and install it into the pool, apply
basic configuration. The fstab says:
/dev/da0s1 /boot/efi msdos rw 0 0
/dev/da0s2b none swap sw 0 0
loader.conf says:
cryptodev_load="YES"
zfs_load="YES"
* copy loader.efi to /boot/efi/efi/boot/bootaa64.efi
* boot into uefi config menu, set console to serial, choose boot device,
set up ACPI+DTB mode, disable memory limit
* kernel boots fine into login shell but reports no DTB found.
Some things don't seem to work correctly:
* if I plug the USB drive into a USB 3.0 port, everything works fine until
root is mounted. At that point, every further disk access fails with IO
errors:
(da0:umass-sim0:0:0:0): READ(10). CDB: 28 00 01 80 a0 c1 00 00 07 00
(da0:umass-sim0:0:0:0): CAM status: CCB request completed with an error
(da0:umass-sim0:0:0:0): Retrying command, 3 more tries remain
This can be worked around using
* a genet ethernet device does not seem to exist and consequentially,
no network connection can be established.
* pciconf -l yields no PCI devices and dmesg suggests no pci bus was
detected (grepping for pci yields no results)
* if I select DTB-only mode in the UEFI configuration, the kernel hangs
during boot. In any case it complains about not having received a DTB.
What can I do to fix these problems? Is there anything I missed?
Yours,
Robert Clausecker
