ESP32-S3 GPIO40 "Strapping Pin" - LED turns on in Bootloader mode

[gotfredsen]

I have an LED on GPIO40. When I start up the ESP32-S3 in bootloader mode, the LED turns on. If I start up normally, the LED is naturally determined my the code.

I just randomly chose that pin, but I really like the LED feedback and want to do that on another project using an ESP32-S2, but the same pin on the -S2 doesn’t light up in bootloader mode.
I can’t find a strapping pin (or whatever this functionality is called) like that other than using the USB pin’s, which I already use for … USB.

Can anybody suggest another "strapping pin", on the ESP32-S2 doing the same thing?
