ESP32-S3 N16R8: GPIO17 high during boot mode

Postby hdsjulian2 » Wed May 22, 2024 11:14 pm

In my design I have a LED attached to the board. GPIO17 is attached to the BLUE pin of the LED.
When i put my board into BOOT mode (pull GPIO0 to ground), the LED turns on Blue, meaning - i assume - that GPIO17 is set to HIGH during Boot?
In my previous version of the board i had the Blue pin attached to GPIO18 and changed it due to this behaviour.
Is there anything I can do to avoid this behaviour or - alternatively - which pins can I use where this won't happen?
