Hi, I'm using a STM32F429ZIT6 controller to interface an OV5640 camera module. I'm interfacing the sensor over 8 channel DCMI. I'm trying to capture RGB565 at high resolution. I'm using DMA with the double buffer on the fly address update feature. I capture the image directly into the SDRAM.
When I try 320x240, 640x480, 800x640 and 1280x720 the DMA is working properly and I am getting the desired image. When I increase the resolution to 1280x1024 the DMA stops exactly midway of the total bytes to be transferred. I checked multiple times and it stops exactly at the same point. I'm getting only half the image at this situation. I thought it was because of a faulty SDRAM but know the SDRAM is working perfectly. I'm using an 8MBytes SDRAM.
I could see that the direct mode error flag is set. How do I prevent or handle this error?
