Hi everyone,
I'm working on a project on SOPine with its Baseboard Model A.
Currently, I want to do some test on the 5MPixel CMOS Camera module bought from the PINE store. But I can't make the camera work(I'm using Xenial Mate OS), I plug the camera in the CSI port and successfully modprobe the s5k4ec and vfe_v4l2 driver, still can't work in both g-streamer pipeline and guvcview app.
Later I found there may be a power issue by probing the CSI port, and I checked the schematic of the baseboard, seems like the power to the CSI port is disabled by default, and the power is managed by the "AXP803" PMIC. I tried to reconfigure the AXP803 to enable the power to the CSI port but I can't detect any i2c device by using the i2ctools, seems the A64 is using a private RSB to control the PMIC.
I'm pretty new to the PINE, so I may miss something. Does anyone know how to enable the CSI port on the baseboard Model A to make the camera work? Thanks in advance.
