Description and Notes

This AMD R5 320 has 2GB of VRAM, uses the Caicos GPU (“Southern Islands”), and was launched in 2014. This card requires a PCIe x16 slot and draws power from the card slot directly.

Raspberry Pi 5

I was able to get the card working by recompiling the Pi OS kernel with the radeon driver, and using yanghaku’s 15 line DRM patch to fix some memory consistency bugs.

I also had to switch the graphical environment to X11 instead of labwc using raspi-config.

See the linked GitHub issue for more details.
