6 years ago I suggest trying with bitmap mode first. See if you get reasonable and stable image. The issue in JPEG mode might be caused by data corruption. It is easier to debug the setup and connections in bitmap mode first, and then go to JPEG mode.

@igrr Here is verbose log! it is seem like work well ,but image is not right in the browser. And could you update Readme about the Ov2640,thank you. ` I (1222) cpu_start: Pro cpu up.
