Failed to init external RAM!

[fah]

I bought this camera: https://www.aliexpress.com/item/M5Stack-Official-ESP32-Camera-Module-Development-Board-OV2640-Camera-Type-C-Grove-Port-3D-Wifi-Antenna/32881414545.html

I've set D2, VSYNC, SIOD and camera type to 1 in main.c

#define M5_CAM_KIND 1 // 1 --> A model, 2 --> B model
// #define FISH_EYE_CAM  // fish eye need flip image
#define CAM_USE_WIFI

#if M5_CAM_KIND == 1
#define CAM_PIN_SIOD    25
#define CAM_PIN_VSYNC   22
#else
#define CAM_PIN_SIOD    22
#define CAM_PIN_VSYNC   25
#endif

//M5STACK_CAM PIN Map
#define CAM_PIN_RESET   15 //software reset will be performed
#define CAM_PIN_XCLK    27
#define CAM_PIN_SIOC    23

#define CAM_PIN_D7      19
#define CAM_PIN_D6      36
#define CAM_PIN_D5      18
#define CAM_PIN_D4      39
#define CAM_PIN_D3      5
#define CAM_PIN_D2      34
#define CAM_PIN_D1      35
#define CAM_PIN_D0      17

#define CAM_PIN_HREF    26
#define CAM_PIN_PCLK    21

I do not know what to enter for modbus as I don't use it I set it to 11,12 and 14 in sdkconfig. Like so

CONFIG_MB_UART_RXD=11
CONFIG_MB_UART_TXD=12
CONFIG_MB_UART_RTS=14

I got this error:

What do I miss ?

Your camera not have Psram, try https://github.com/m5stack/m5stack-cam-psram/tree/NoPsram

You are right. I thought the SRAM is the same as PSRAM. Thank you.
