ArduRemote v1.14 Caught in Bootloop on ESP32-S3

Hi everyone,

I'm trying to flash the latest version of ArduRemoteID (v1.14) onto an ESP32-S3-DEVKITC-1N32R8V.
However the ESP32 seems to be caught in a boot-loop, and I'm not sure on how to proceed with this.

Connecting to the ESP32's USB port via Putty yielded the following printout. It loops multiple times a second.

# Steps to Recreate

I followed the instructions here, using the exact same settings: https://github.com/ArduPilot/ArduRemoteID/tree/master?tab=readme-ov-file#flashing

1. Downloaded the prebuilt `ArduRemoteID-ESP32S3_DEV.bin` for `v1.14`

2. Used the ESP32 Download Tool to flash the .bin file to addr `0x0000`

# Debugging

I've tried the following steps so far, all yielding the same results:

- Used a different ESP32-S3 dev board
- Used an older release of `ArduRemoteID (v1.13)`
- Switched to `ESPTOOL` for flashing
- Increased / Decreased the flash memory size
- Validated the addresses of the `.bin` file, and the bootloader. (See attached CLI outputs)

Any thoughts on what could be the source of the problem?
Thanks in advance.

Start with the repository's README flashing instructions and the ESP32-S3 binary and esptool commands shown in the report. Reproduce the boot loop and compare the documented procedure with the reported board and image details; done means identifying a concrete cause or documenting a correction.
