AMD gpu driver error

[D3CIM8OR]

I have a Dell Inspiron 5575 that I'm trying to install FreeBSD on. The display driver isn't being loaded by default, so I followed the instructions in this link. Specifically, I used the AMD GPU driver. On startup, the display driver isn't being loaded so I ran dmesg -a | grep amd and got the following output

[drm] amdgpu kernel modesetting enabled
drmn0: successfully loaded firmware image with name: amdgpu/raven_gpu_info.bin
[drm:amdgpu_get_bios] Unable to locate a BIOS ROM
[drm] amdgpu: finishing device

I am assuming that the error lies in

[drm:amdgpu_get_bios] Unable to locate a BIOS ROM

I was unable to find anything online about this issue. I know that the display driver isn't being run because my resolution never increases from 640x480 and startx fails with "no screens found". Does anyone know how to fix this issue? Thanks!

What AMD GPU model is that?

Does anyone know how to fix this issue?

We don't fix issues there. "Fix" is the term reserved for developers.

According to pciconf -lv, it is an AMD Raven Ridge [Radeon Vega Series / Radeon Vega Mobile Series]

Does installing sysutils/devcpu-data solve the issue? Is your system up-to-date ?

Do you have
hw.syscons.disable=1
in your /boot/loader.conf ?
