NetBSD running at full resolution on my RPi!

Following my latest article about running NetBSD on a Raspberry Pi, I asked for advice on Mastodon, to see if folks had an idea how to fix the issue I had with NetBSD not using the entirety of the screen.

I got a quick answer from Vermaden who gave me pointers.

Turns out that the first link was exactly what I needed!

Here's what I did:

Mount the SD card on my FreeBSD laptop

mount_msdosfs /dev/da0p1 /mnt/usbdisk/

Edit the config.txt file:

vi /mnt/usbdisk/config.txt

Add the following lines at the bottom of the file:

hdmi_cvt=800 480 60 4 0 0 0
hdmi_group=2
hdmi_mode=87

As explained in the article, the 800 and 480 values in hdmi_cvt are the screen resolutions.
The 4 value means a screen ratio of 5:4, which is the closest I could find from the 5:3 I have (800x480)

When I booted the Pi with this updated configuration, I was thrilled to see that it worked, see below picas!
