I have the beta (orange film) version of the Seeeduino FILM boards and am having some problems connecting to it with avrdude.
I’ve tried using the UART 3.3V connection and the ISP header connection.
I’ve managed to actually flash a new program onto the FILM using the USBtiny ISP programmer but that was only after about 10 tries
and consistently getting the message:
"avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check. "
It seems like the PTH on the FILM is very fragile/fussy and prone to not making contact w/ the header pins I’m using to pin the FILM down onto a breadboard.
Can the ISP header take 5V or does it also require 3.3V too ?
I’m very excited about the possibilities that the Seeeduino FILM presents, I will admit that I’m getting frustrated just trying to reliably upload to the board though.
Thanks for any help you can provide…
