so I came across a weird problem with my due recently. I tried to connect the rx0 and tx0 to another microcontroller, this worked well, but now that I try to upload software over my usb programming port the arduino seems to be unable to receive data. He's detected and it also blinks once data is send to the usb port, but he's neither processing this data nor responding to it.
Like this the due is unusable. Do you have any suggestions how I can get it back to work? I already tried rebooting/reinstalling windows and drivers and I erased the storage on the due but nothing helped yet.
I take it you've removed all connections to TX0 and RX0 now.
Normally an erase should put everything into a workable state for downloads, but
any issue with a USB serial connection it may be wise to disconnect, kill the
IDE, wait 30 seconds and restart, in case the USBserial driver has got confused -
a brand new connection should be in a known state.
Hi,
I got the same problem and certainly I had been tried the actions that Mark advices , but did not worked also.. Before dump the board, I just noticed "erase" button on the board ( I did never used this button before.. ) and pressed for few seconds.. uups, it started to work..
