Bootloader mode without (physical) button press?

Post by Hansipete »

Hej!

I have a simple Tinket M0 application that was working flawlessly for several months but recently (only once) had bootloader mode enabled without the reset button being touched at all.

Anyone every experienced this?

For context: The Trinket has just a hall sensor (AH3362Q, https://www.farnell.com/datasheets/2263959.pdf) connected to it, using pins 0 1 2 (0 pulled high and 1 pulled low for power supply, 2 for reading the analog signal). It's connected with a rather long (5m) USB cable to the computer. It's transmitting the hall sensor status (0 or 1) every 20ms.

Any chance that there's a situation where Tinket could enter bootloader mode without the button pressed?

Thank you very much,
Hans

You can connect to the Trinket via serial terminal at 1200 baud which should put it into bootloader mode without having to press the button.
