Title: dead tinyzero
Post by: Erik on June 12, 2026, 09:21:29 AM
Hi all,

I tried to flash a .bin file using bossac (.\bossac.exe -e -w -v -b .\Blink.ino.bin) but it crashed after the first erase step.
Now I cannot communicate with the tinyzero. There is a single blink of the LED when I power the tinyzero, but that's it.

What I have tried
- double click bootloader button
- double click bootloader button right after power on
- power on while holding boot loader button
- plugging in while uploading using Arduino IDE
- removed the COM ports from windows device manager

Non of the actions resulted in the com port apearing in windows device manager, arduino IDE, bossa UI or me being able to upload a new sketch

Any suggestion would be appreciated

Erik
