ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. When using a bootloader from these ESP-IDF versions and building a new But the board is not bricked - it runs the bootloader and app just fine, and I can update the app using OTA. // Return global reent struct if any newlib functions are linked to bootloader Note! You do not need to update your UF2 bootloader to update CircuitPython! If you already have CircuitPython on your ESP32-S3, you just need to boot the board into UF2 bootloader mode, and then copy the latest CircuitPython UF2 firmware file onto the drive via the file manager you use on your computer. Could this be a cause of the problem: the flashing was done by a script that (a) flashed the bootloader (without reset after), then (b) flashed the app (which did a hard reset after), then (c) 10 seconds later used esptool. On ESP32-S2/S3, there is no bootloader protection for the UF2 bootloader I recently acquired an ESP32-C3-DevKitC-02 module, and, as I tend to do, jumped right into reading about how the system boots and how the (pretty good!) tooling Espressif offers works. For the bootloader reflash: Sending the key to the computer would weaken it, because it would mean it's available in an extra location which can be breached; keeping it in the ESP32 and letting the ESP32 do all the work is more secure.
