Dear Colleagues,
I am experiencing an issue with my Arduino Pro Lite controller. After several weeks of stable operation, the controller has frozen. When I attempt to reload the firmware in "normal" mode, I receive the following message:
"No DFU capable device available/exit status 74".
The device does not enter DFU mode with a double press of the Reset button. However, with certain manipulations of the Reset button, I can sometimes get it into DFU mode.
Once in DFU mode, I am able to upload a basic program, such as:
void loop() {
digitalWrite(LED, HIGH);
delay(50);
digitalWrite(LED, LOW);
delay(50);
}
The program uploads successfully, but the LED blinks significantly slower (approximately 100 times slower than expected).
Could you please advise me on how to restore the full functionality of my controller?
Regards
