no UART! The pinout is different see Bus Pirate V4 pinout, so need to update firmware.

When trying to umount a USB Pendrive I had the following message: umount: /mnt/sd: Device busy doing:

port:fred /mnt> doas fstat /mnt/sd

revealled what the issue was.

Raspberry Pi Recovery

This topic is covered on the Downloads page, but trying it in my Raspberry Pi 3 Model B v1.2, however using the bootloaders did not seem to fix my pi. Ended up using the Raspbian Buster Lite image flashed to an SD card and used HDMI and USB keboard.

now need to try to reinstall OpenBSD.
