zBitx upgrading the firmware.

 

The zBitx displays the sbitx and firmware versions on startup.
How do you know if you have the latest versions? Is there a version name or tag in github or the firmware file?

Either works. But the old and new dont interoperate. So, I would recommend doing the Pi first

The documentation should be here in the next 12 hours. But here is how you upgrade the firmware:
1. Go to ?
2. Download the uf2 file to your computer.
3. Unplug the zbitx power.
4. Keeping the knob button pressed, attach the supplied USB cable between the PC and the CAT USB port on the zbitx.
5. Remember, you have to attach to the CAT USB port, not the other.
6. Now, let go of the knob pressed. The zbitx front panel will light up with an all grey screen. The Pico controller will show up as a drive on your PC.
7. Copy the .uf2 file from the PC to the Pico controller.
8. You are done, remove the USB cable. Start up the zbitx.
9. The latest firmware should show up on the front panel.
