i.MX6使用NVP6324獲取影像問題

jerrypyliu

主要參考以下這篇進行driver的移植imx6上:
http://community.nxp.com/docs/DOC-344148

目前使用BSP版本為4.1.15
並參考ov5640_mipi的寫法
已有成功驅動driver
也確認NVP6324是有MIPI訊號輸入
(讀取bank 0 0xa4~0xa7位置判斷)

不過測試l獲取影像時會遭遇到:

1. In MVC: mxc_v4l_dqueue
   
2.    width=288, height=352, size=152064, format=32315559
   
3. ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0

复制代码

想問可能是什麼原因造成的呢?
