I’ve been trying to load up a demo firmware on ESP32-S3-Zero (FH4R2) - (4 MB Flash and 2 MB PSRAM). I can upload the code to the device with trial and error (as I’m new to ESP32), but after resetting, the Serial monitor goes:
E (73) cpu_start: Octal Flash option selected, but EFUSE not configured!

Do you have any suggestions on how I should divide the partition for using a bigger app and have some space in SPIFFS storage as well? As later on, I plan on hosting it on a board with a camera, so I would need to store images on SPIFFS.
I can upload the demo application that Waveshare provides through the FlashDownloadTool with their given bin files. Can I use their partition.bin or bootloader.bin with my own firmware.bin file?
I tried looking for answers to this but couldn’t find the reason.
Another follow up question: as I intend to use a camera, I will have to take reference from the CameraWebServer application and will have to use their camera_pins.h file
However, as I have little hardware knowledge, which board pin settings from the 5-6 ESP32-S3 versions in this file would be compatible with my “ESP32-S3-FH4R2”? I was gonna go for the CAMERA_MODEL_ESP32S3_CAM_LCD, but as you mentioned earlier, this one has octal flash, and mine has quad, so I’m assuming the GPIO pin settings might be different as well, right?
These are the ESP32-S3 options available from the camera_pins.h file:
The pin definitions specify which camera pins are connected to which pins of the ESP32.
But the ESP32-S3-Zero to which you refer does not have a camera.
Therefore you will not find corresponding ready-made pin definitions for your board anywhere.
