UNSOLVED OrangePi cm5-tablet RAW-MIPI-SC132M

mparem

Hello, I am trying to connect veye RAW-MIPI-SC132M to OrangePi cm5-tablet.

Following the instructions from https://github.com/veyeimaging/rk35xx_orangepi/tree/main/linux,
I cloned:

https://github.com/orangepi-xunlong/OrangePi_Build
https://github.com/veyeimaging/rk35xx_orangepi/tree/main
https://github.com/veyeimaging/rk35xx_veye_bsp
ran an empty build to generate the base structure (sudo ./build.sh)
copied the drivers from the bsp repo
copied the configs
modified the device tree files:

sudo dmesg | grep mvcam does not output
mvcam 1-003b: camera is: RAW-MIPI-SC132M
mvcam 1-003b: firmware version: 0x1040000

instead, I see
platform csi2-dcphy0: Fixed dependency cycle(s) with /i2c@fec80000/mvcam@36

Any help would be much appreciated.

Best regards,

Mikhail

@mparem

mvcam's i2c address is 0x3b, not 0x36.
please set rkcif_mipi_lvds's status as okay.

good luck!

update: I modified the device tree a few times, and reached a different error message:

i2c-6: Failed to create I2C device for /i2c@fec80000/mvcam@3b

How can I verify that the drivers were correctly installed?

neither lsmod nor less /proc/modules show anything veye-related

veye_xumm

@mparem
Because on the RK platform, the mvcam driver needs to be built into the kernel, it will not appear in the lsmod list.
Please send me your current DTS and the related error so I can take a look.
The cam2 interface on the tablet corresponds to dcphy0 and i2c6, which is correct.

tablet_3b2.dts.txt

This is the decompiled dts, which I modified (set i2c address to 0x3b and changed compatibility to veye,mvcam), compiled, then moved back into /boot/dtb*/rockchip/rk3588s-orangepi-cm5-tablet.dtb (faster than recompiling with orangepi-build)
