I just resoldered the joints on all the components you listed. Before and after, while connected w/ the FTDI adapter, the board has power and the preloaded software comes up on my TV. I already reconfigured the adapter’s hardware ID and ran another loopback test which was successful, but there is still no response while uploading.
EDIT: Fixed! I had the adapter backwards from the beginning.
There is only one serial port that it automatically registers under and I still get the same no response error. I just tried a loopback test which was successful but the hackvision itself still won’t respond while uploading.
