I am attempting to upload a *.bin file to a fresh TinyFPGA BX board. I started getting the error above so I tried simply switching the board into bootloader mode using the following command:
sudo tinyprog -b -d 1d50:6130
I received the following message (identical to the error I got running -p hardware.bin):
Using device id 1d50:6130
Only one board with active bootloader, using it.
… followed by a traceback with a number of calls, and finally:
'device reports readiness to read but returned no data ’
serial.serialutil.SerialException: device reports readiness to read but returned no data (device disconnected or multiple access on port?)
Any thoughts? Perhaps some USB issue on my machine?
