STM32F429 Interface with OV5640

Question asked by Narendra Suthar on Feb 14, 2017

Hi,

 

I have interfaced OV5640 camera with STM32F429VI using DCMI and DMA. 

I am capturing JPEG image. The data of image storing in external SRAM using DMA. SRAM size is 512 x 16Bit.

I can able to store image which has size below 256KB in SRAM.

If image size increase beyond this then STM is not receiving DCMI_IT_FRAME interrupt. 

I have checked camera VSYNC, HREF and PCLK signal in this case. They are same as earlier.

 

Please help me to resolve this issue.
