MIPI CSI-2 frame dump

shajinas — Tue, 19 Jan 2016 18:15:54 GMT

Hello,

I'm exploring MIPI CSI-2 interface in SABRE SD Platform which uses Omnivision ov5640 camera. My understanding on MIPI is very minimum. I wonder, Is there any way in kernel space the captured frame can be dumped/print ?

Thanks for your time..

Regards

Shajin

Hi Shajin

I am not aware of ways of dumping mipi captured frame, probably

one can write own application using sect.20.3.3 Programming Interface

mipi driver attached Linux Manual. Problem is that mipi has not accessible

data frame buffer, as it uses MIPI CSI to IPU Gasket (CSI2IPU), data is passed

directly to IPU. IPU data is processed with DMA (IDMAC). So for dumping

captured frame both MIPI and IPU should be programmed.

Best regards

igor
