ESP32 Forum

Hi Espressif Support Team,

I am developing a custom hardware with ESP32 S3 WROOM N8R8 and OV2640. I had faced an issue where the PSRAM was not working. Then I realized that couple of pins in GPIO 33-37 range was assigned. Using this was causing a PSRAM issue. We were not able to read and write to PSRAM.

Then I changed the pins accordingly as below. Now, I am able to detect PSRAM, but the video read is still not working
The camera pins now that are configured are as follows
#define CAM_PIN_SIOD 38 // SCCB SDA
#define CAM_PIN_SIOC 3 // SCCB SCL // new change
#define CAM_PIN_D5 13
#define CAM_PIN_PCLK 18 //new change
#define CAM_PIN_D6 11
#define CAM_PIN_D2 12
#define CAM_PIN_D4 47
#define CAM_PIN_VSYNC 7
#define CAM_PIN_D3 14
#define CAM_PIN_HREF 15
#define CAM_PIN_D9 8
#define CAM_PIN_XCLK 21
#define CAM_PIN_D8 9
#define CAM_PIN_D7 10
#define CAM_PIN_PWDN -1
#define CAM_PIN_PWR 16
#define CAM_PIN_RESET -1

Do you foresee any issues in this pin assignment?

I have added the logs that I am seeing as an attachment.

Can you help me figure out what the issue is?

Thanks and Regards,
Subbu
