Ok, can’t try anything because I tried to upload the latest 0.9beta to my Arduino UNO, but forgot to disconnect the Ethernet shield. When I tried to upload, it shows:
vrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x00
Disconnected the shield, even tried a different UNO - same errors.
Installed Arduino IDE on a Windows machine, same errors.
Tried to upload a Blink program through platformio, same errors on both boards.
Tried a different USB cable.
Loop test doesn’t seem to work.
The worst thing is that the OMG that was working now does not work when I connect it back (it blinks its LEDs on the Ethernet shield, but I can see no mqtt messages from OMG at all). It shows nothing in Serial Monitor in Arduino IDE.
How 2 boards could die simultaneously? Have you ever heard about something like that?
