I am working on "MCIMX8-8X-BB - i.MX 8QuadXPlus Multisensory Enablement Kit (MEK) Base Board" with a board MX8XMIPI4CAM2 (4 camera bard with miniSAS connector for OV10635 MIPI Camera) and 4 MCIMXCAMERA1MP (OV10635 sensor based LVDS camera with Maxim serializer) connected. I try to see video from each one of the 4 cameras but I only see video when use /dev/video0. I saw a chat regarding a similar issue with the driver for MAX9286 and the answer was that the iMx8QXP with Silicon rev B0 could not support or has problems when multiplexing the 4 cameras and only works with one (/dev/video0). I check my MEK board and it has a label "Si B0 SECO". I want to know if this label is the silicon revision? and if so, what will be the steps to follow for upgrade my board to have another silicon revision that can work with all cameras?


Thanks in advance for your help.
