I've fixed a couple of problems, and gotten a little further, but the kernel is still crashing before it prints the banner. This is a custom bootloader, for a custom PCB, that I wrote from scratch back in 2016. > > I am not sure, but I think there was some change in boot process, so > your 11-compatible bootloader is probably no longer compatible with > 13.0 kernel.

I needed to: 1. update my .dts to reflect the default zybo .dts settings, and include "zynq-7000.dtsi" from the source tree. 2. add the "xlnx,zynq-7000" string to the "compatible" key. That solved the problem with the "No platform module found!" panic. 3. add "freebsd,dts-version = "5.9";" to the dts file, which is something that the FreeBSD build system adds automatically when compiling dts files. > Could you verify your serial port settings?

After I did #2, above, then the serial output started working, so it seems it is still expecting the same settings (uart 1, 115200/8/n/1) as FreeBSD 11. Now I am to the point of getting another crash, with no panic message, that dumps me into the KDB debugger prompt. > > There is some push towards using efiloader for loading kernel. I have > no specific answer on kernel environment... If anyone could point me to the code that sets up the metadata and environment so the kernel can run, that would be super helpful. Right now I am still using the same metadata structures that I used for FreeBSD 11. Thanks, Lee
