Why is it that sometimes black screen appears after I change my wince6.0 s5pv210 ov3640 to pixels?

By gooogleman@foxmail.com

In the past, my s5pv210 was 640*480 resolution. Now, at the customer's requirement, I changed it to a real ov3640 2048 W pixel 1536 * photo. Sometimes, when I opened the camera app, the screen was black, nothing is displayed.

But looking at the dnw information, I read the camera ID, and it is not bad. What's going on? An error is prompted later. check it first.

Hey, it has been solved. It was originally caused by the bug that s5pv210 wince6.0 camera driver occupied too much memory. We can solve this problem by changing the memory occupied by taking photos of W ov3640 pixels in the former way. Hey.
