Wrover Kit - SCCB_Write failed

[GermanSheepDog]

Hello Maxim,

I used a Wrover Kit camera and if I started the monitor, I got this error:

WiFI ready
I (4821) esp32_camera: Free heap: 230212

What can I do?

You should find out the mapping between the gpio-pins and the camera function pins.

This is what I found in a camera app. it should be a good start, but no guarantees ;-)

Hello Maxim,

for WROVER_Kit from TTgo (exactly: TTGO T-Kamera ESP32 WROVER & PSRAM Kamera Modul ESP32-WROVER-B OV2640 Kamera Modul 0,96 OLED) this worked for me:

if CONFIG_CAMERA_MODEL_WROVER_KIT

define CAMERA_PIN_PWDN   26

define CAMERA_PIN_RESET  -1

define CAMERA_PIN_SIOD   13

define CAMERA_PIN_SIOC   12

define CAMERA_PIN_XCLK   32

define CAMERA_PIN_D0      5

define CAMERA_PIN_D1     14

define CAMERA_PIN_D2      4

define CAMERA_PIN_D3     15

define CAMERA_PIN_D4     18

define CAMERA_PIN_D6     36

define CAMERA_PIN_D7     39

define CAMERA_PIN_VSYNC  27

define CAMERA_PIN_HREF   25
