Steps to reproduce the behavior

1. I migrate the 9281 driver for esp-camera
2. pclk->26Mhz

Project release version

v2.0

System architecture

Intel/AMD 64-bit (modern PC, older Mac)

Operating system

Windows

Operating system version

win10

Shell

ZSH

Additional context

there is no valid data in DMA while vsync intr, i want to know what actions would cause this phenomenon

hello, I'm working on migration of OV9281 to ESP32S3 either. my mail address: 3195016438@qq.com. Wish to discuss with U :)

hello, did you figure this out?

hello, did you figure this out?

increase the HTS and VTS timming, especially HTS. There should be enough free time left to handle DMA data for the ESP32
