FB-SIZE issue on ESP32-CAM with BF3005.

[AthenasArch]

I'm having trouble configuring the BF3005 camera on the Arduino IDE with ESP32.

It returns the log: E (8433) cam_hal: FB-SIZE: 149760 != 153600

And, if I understand correctly, the calculation is FRAMESIZE_QVGA = 320 x 240 x 565bits color

then 320 x 240 x 2 = 153600, is that correct?

but I don't know why the camera is returning me: 149760, can you help me?

```c
void setup() {

    WRITE_PERI_REG(RTC_CNTL_BROWN_OUT_REG, 0); //disable brownout detector
    // put your setup code here, to run once:

Hello, @AthenasArch , Can it work properly when configured as VGA ?

[Abhay-2412]

Hello i'am also getting same error , i'am uisng OV5640 camera and trying to use PIXFORMAT_YUV422 pixel format with frame size FRAMESIZE_HVGA below is the camera configuration

esp_err_t initCameraSettings(void)
{
  //Camera configuration
  config.ledc_channel = LEDC_CHANNEL_0;
  config.ledc_timer = LEDC_TIMER_0;
  config.pin_d0 = Y2_GPIO_NUM;
  config.pin_d1 = Y3_GPIO_NUM;
  config.pin_d2 = Y4_GPIO_NUM;
  config.pin_d3 = Y5_GPIO_NUM;
  config.pin_d4 = Y6_GPIO_NUM;
  config.pin_d5 = Y7_GPIO_NUM;
  config.pin_d6 = Y8_GPIO_NUM;
  config.pin_d7 = Y9_GPIO_NUM;
  config.pin_xclk = XCLK_GPIO_NUM;
  config.pin_pclk = PCLK_GPIO_NUM;
  config.pin_vsync = VSYNC_GPIO_NUM;
  config.pin_href = HREF_GPIO_NUM;
  config.pin_sscb_sda = SIOD_GPIO_NUM;
  config.pin_sscb_scl = SIOC_GPIO_NUM;
  config.pin_pwdn = PWDN_GPIO_NUM;
  config.pin_reset = RESET_GPIO_NUM;
  config.xclk_freq_hz = 24000000;
  config.pixel_format = PIXFORMAT_YUV422;
  if (psramFound())
  {
    config.frame_size = FRAMESIZE_HVGA;
    config.jpeg_quality = 20;
    config.fb_count = 2;
    config.grab_mode = CAMERA_GRAB_WHEN_EMPTY;
    config.fb_location  = CAMERA_FB_IN_PSRAM;
  }
  else
  {
    config.frame_size = FRAMESIZE_SVGA;
    config.jpeg_quality = 12;
    config.fb_count = 1;
  }

and i'am getting below logs

E (50637) cam_hal: FB-SIZE: 294400 != 960000
E (51459) cam_hal: FB-SIZE: 294400 != 960000

E (53925) cam_hal: FB-SIZE: 294400 != 960000

and an important thing to be noted is PIXFORMAT_JPEG works fine its not throwing any error and when i try to use PIXFORMAT_YUV422 IN Arduino IDE it's work fine

Man, this could be your camera's resolution size setting. I adjusted the settings to what the datasheet says and it worked.

This software has been tested on the camera BF3005.

hello @AthenasArch what about ov5640 its not suporting yuv422 format in esp idf but when i run same code in arduino ide and flash it it works perfectly do i need to change any menuconfig settings can you tell me and what's this error mean E (53925) cam_hal: FB-SIZE: 294400 != 960000 and why this 960000 is constant i think i need to change this but i donno how to

[AthenasArch]

This error occurs when the format you are trying to send to the camera is different from the ideal format for the camera. It is usually related to camera resolution and frequency. I recommend you set a lower frequency, closer to 10000000

     config.xclk_freq_hz = 10000000;
     // see datasheet to configure this: pixel_format. 
     config.pixel_format=PIXFORMAT_RGB565; //PIXFORMAT_GRAYSCALE; //PIXFORMAT_YUV422; //PIXFORMAT_YUV420; //PIXFORMAT_RGB565;
     // if PSRAM IC is present, boot with UXGA resolution and higher JPEG quality
     // for larger pre-allocated frame buffer.
     config.frame_size=FRAMESIZE_HQVGA;
     config.jpeg_quality = 4; // See ddatasheet
     config.fb_count = 6; // See ddatasheet
     config.grab_mode = CAMERA_GRAB_LATEST;
     config.fb_location = CAMERA_FB_IN_PSRAM; // if you use PSRAM.

[Abhay-2412]

Hello @AthenasArch, I appreciate your response. Regarding the YUV422 format, I understand that a frequency of 24MHz is required. I have successfully implemented the same configuration in the Arduino IDE, and I am able to view photos. Therefore, I believe that there might be some adjustments needed in the menuconfig settings. If you require any additional information, please let me know. Thank you.

[Abhay-2412]

Hello @AthenasArch i have tested what you have suggested by lowering the frequency still im getting same error no change
