I am using i.mx6q SD board to get two camera(ov5640 and ov3640) work at the same time.

It is no need to display the image on display, i just want to get the camera datas in memory and

save them to local files.


To confirm is it support two camera at the same time, I do the follow things:

1. Put the OV5640 camera image on display with mxc_v4l2_overlay.

2. then capture the OV3640 data to local file with use mxc_vpu_test


But i got following error when i do second step:

imx-ipuv3.0: handler already installed on irq 0


So i checked the drivers,and found that there is only CSI_MEM(which is CSI_MEM0),

I think that if want use two cameras at the same time,

It is need to add a CSI_MEM1  to let second camera data use CSI_MEM1 channel to memory.


Am i right? and is there any ideas to save two camera data to memory at same time?


Thank you.
