I’m also having a lot of trouble getting the TInyFPGA board working on MacOS.
The underlying problem seems to be that the “tinyprog” program just can’t
see the board.
I’ve tried most of the ideas posted here (and thanks for all that!).
MacOS 10.11.5 (El Capitan)
board plugged into USB: TinyFPGA BX
the red LED looks like it is breathing. (that’s good I assume)
I pretty much get the same output from tinyprog for each variation (–libusb or --pyserial):
It just can’t find the board.
$ tinyprog --pyserial -l
Using device id 1d50:6130
No port was specified and no active bootloaders found.
Activate bootloader by pressing the reset button.
I noticed that the Serial app doesn’t see the tinyFPGA board at all.
It sees an Arduino Uno just fine.
But, when I hold the reset button, Serial shows some kind of CDC device,
that vanishes as soon as I let go.
I’m really stuck here.
Does anyone have this board working with a similar Mac?
