Hi, according to the note in the schematics of ESP32-Camera, IP5306 should be connected to I2C:

However, schematics doesn't show any such connections and on the default module without any other I2C devices no I2C device can be found. IP5306 should be available at 0x75.

Is the chip really IP5306_I2C, so I can make a custom connection?

I have trouble getting this camera working with custom firmware. Original firmware worked ok.
When I flash CameraWebServer example, with #define CAMERA_MODEL_M5STACK_ESP32CAM // No PSRAM used, it fails with:

E (124) cam_hal: cam_dma_config(271): frame buffer malloc failed
E (124) cam_hal: cam_config(355): cam_dma_config failed
E (124) camera: Camera config failed with error 0xffffffff
Camera init failed with error 0xffffffff

I've double-checked the pin are set according to the M5Stack documentation.

I'm using ESP32 Arduino SDK 2.0.0. There is no special board definition for M5Stack ESP32-CAM, I set classic ESP32 board, DEVKIT V1.
Does anyone know what could be a problem?
