Unable to use GPIO pin 16 for LEDs

[benliles]

What happened?

Unable to configure the GPIO pin that I previously used after resetting and flashing to 0.15.3. Downgrading to 14.4.4 did not help. Erasing and flashing from scratch and 14.4.4 is still broken.

Sorry, pins [11,12,13,14,15,16,17,0] can't be used.

To Reproduce Bug

esptool erase-flash
esptool write-flash 0x0 esp32_bootloader_v4.bin

From here, I flashed with esptool AND tried the install.wled.me install. Both reset all of my settings.

Expected Behavior

I expected to be able to configure the GPIO pin 16 that I had previously used.

Install Method

Binary from WLED.me

What version of WLED?

WLED_0.15.3_EESP32-C3.bin

Which microcontroller/board are you seeing the problem on?

ESP32-C3

Relevant log/trace output

Anything else?

My understanding is that the inclusion of the audioreactive usermod in the default build is causing this. I do not see the audioreactive mod on the /settings/um page and cannot disable/change the pins.

I downgraded to 14.4.4 and received the same error.
I used esptool to erase, reload the bootloader, and flash again to 14.4.4 immediately and the problem did not go away.

on C3, GPIO16 is an SPI flash pin and has never been available.
If not a C3, check usermod settings.

GPIO16 is tied to LED channel 1, maybe the board isn't C3. I recall there was a custom firmware at some point for this setup but I cannot locate it any longer.

The usermod settings aren't showing audioreactive and the mods that are there are all set to be "unconfigured" for pins.

Musing, I wonder if it would be possible to provide the source of the conflicting pin registration when showing the error. That would make diagnosing this issue much easier.

I just moved to a different a different pin on the board.
