I would like to share an issue concerning the OPI Zero 2+ with the camera module.
I was not able to work with it and I got usual error :
[ISP] isp platform_id = 5!
[CSI_ERR][GC2035]sensor_read err at sensor_detect!
[CSI_ERR][GC2035]chip found is not an target chip.
I finally found that the FEX was incorrect.
On line 384, the port definition was wrong and should be PA08 :
vip_dev0_power_en = port:PA08<1><default><default><default>
Then the camera is recognized :
[ 8652.370168] [ISP] isp platform_id = 5!
[ 8652.447812] [CSI][GC2035]V4L2_IDENT_SENSOR=2035[CSI][GC2035]disalbe oe!
And worked properly with fswebcam :
fswebcam -r 1600x1200 -p YUV420P - > cam1600x1200.jpg
Maybe someone can tell me where to report the bug ?
Hope my post may help. I attached the corrected FEX file (note that I did not check other parameters).
Use fex2bin to create script.bin and put it in /boot.
