I found that problem is with loader and dtb file. Ubldr now seems to ignore uboot.fdtfile=bcm2835-rpi-b-rev2.dtb enry. If i am doing in loader: "load -t dtb bcm2835-rpi-b-rev2.dtb" and then boot - it loads as expected. I can see var in the "ubenv show" output, so it makes me thinking that loader simply ignores it. As temporary workaround i am using now fat partition from the 11.2-RELEASE Some additional data: new firmware of rpi, which is installed in the loader, automatically loads bcm2708-rpi-b.dtb file. This file seems to be taken from and is not playing well with a FreeBSD. ubldr detects that this dtb is loaded by u-boot and is not loading one from FreeBSD /boot directory. Also if i am enforcing RPi loader to use file from /boot - u-boot hangs and i have a black screen on load I been able to load FreeBSD with a loader from FreeBSD 11.3 using such hack:

This needs to be fixed on upstream, not sure about correct way to handle that.
Hi Oleksii, Would you please confirm if only updating boot/loader.4th with your patch is all what is required to boot 11.3 version? Now I'm running 11.2 but I'd like to upgrade. I tried with 12.x with no luck. Thanks! |
I found that there is a regression on RPi1/FreeBSD. When i am copying official image to the SD card i am getting boot loop. Previous (11.2) version works just fine on the same hardware.
