Hi Stephen,
This one sounds very odd, we’ll work on getting a system set up on our end with some instructions on getting the ESP-CAM flashed.
David also had a very good method of flashing a similar ESP32 module in this topic: FireBeetle ESP32-E IoT Microcontroller with header (Supports Wi-Fi & Bluetooth) (DFR0654-F) - #3 by Liam120347
Here’s a link to his website and guide: My First IoThing | dfoley.ie - David Foley's home on the WWW
We’ll let you know how our testing goes!
Liam
