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.
