Hey Pete,
I tried compiling first as an AI-thinker ESP32 CAM which has no partition options. Then I remembered that I need to upload as an ESP32DEV module to have OTA available and the partition scheme I use is:
Minimal Spiffs (1.9Mb App with OTA, 190kb spiffs).
The error is the same with either board selected, but it seems to reference different memory addresses depending on board, and changing the reset pin in settings.h
