ESP32-S3 Hard resetting RTC WDT

Postby lsheaf » Sat May 31, 2025 12:05 am

Hey guys

I just had a new board made with an ESP32-S3. I've tried everything practical but I keep getting

Leaving...

Hard resetting with RTC WDT...

and serial monitor is spazzing out with "no bootable app partition"

I'm completely lost at this point.


mode:DIO, clock div:1


load:0x3fce2820,len:0x118c


load:0x403c8700,len:0x4


load:0x403c8704,len:0xc20


load:0x403cb700,len:0x30e0


entry 0x403c88b8

Did you flash anything to the chip?

Yes I flashed it multiple times and different ways. Using esptool app and online web version.
I have a feeling this is simple but I've never seen this before.

Maybe you're only flashing the app to the ESP32? You need to also flash the secondary bootloader and the partition table.

Okay so i fixed the no bootable partitions error. I'm getting a hard resetting vis RTS pin now with no code output on the serial.
I've tried various different USB-C cables with the same results.
