      I  have two Omivision OV10640 Camera Modules and a sbc-s32v234 board on my hand. I want to use them for stereo vision development. I build the isp_ov10640_default demo and run it sucessfully(with one OV10640 Camera module connect to the MIPI-A Port), But when I connect the camera module to MIPI-B Port, and modify the main.cpp  to add


to access to the MIPI-B Port.

(the complete main.cpp is attached. )

Howevere , it fail and display the following error logs:


../../../../../libs/isp/sequencer/user/src/seq_user.cpp: 182/SEQ_Reserve : [Error]: Can't open device file: seq

How can I acesses the Omnivision OV10640 Camera through MIPI-B Port?

And If I want to connect two OV10640 Camerta Module(One connected to MIPI-A,and the other connect to MIPA-B),What should I do?I am looking forward for your answering.
