Help Neeeded Troubleshooting A2DVI

Hello Friends:

I need some help troubleshooting an A2DVI.  I am building an A2DVI v2.0 card.  The card is not working.  After several efforts to validate solder points, etc, I determined the problem seems to be the Pi Pico.  When I drag and drop the firmware (2040 varriant) on to the Pi Pico (mounted as a storage device) it flashes S-O-S on the LED.  No matter what I do the firmware will not load.

 

1) I know I am using the correct version and not the version for the Pico2.

2) I have tried using flash_nike.uf2 to clear the pico.

3) In a "why not" effort, I used Thonny to reinstall micropython on the Pico then added the firmware.  No joy.

 

Any suggestions?

Mark

Solved

Solved. Not sure why this worked, but I installed the original v0.7 firmware. Ran the flash_nuke then began in stalling earlier versions one at a time, with flash_nuke between each install. Works. Not going to question this positive turn.
