What is the frame rate at 48 Mhz? Can you please check if you have any buffer overflow errors? (CyU3PDmaMultiChannelCommitBuffer Api returns error).
I have checked. There is no buffer overflow errors.
The resolution of sensor: 1280x1024. The frame rate is 30fps at 48MHz.
I use the usbmon to monitor the amount of usb bus. The result is as follows:
1) 27MHz: the amount of the usb bus is 2621440=1280*1024*2, it is right, the image is normal.
2) 48MHz: the amount of the usb bus is 2623488>1280*1024*2, it is incorrect, which results in the sideling image.
