Camera sensor os02g10 MIPI CSI for IMX8MM Hi all. I got the driver for os02g10 from: https://github.com/Shaggy013/kernel-5.10 I added driver as a patch. My DeviceTree looks that: csi1_bridge: csi1_bridge@32e20000 {

}; I modified probe function for camera driver and for mxc_mipi-csi.c, mx6s-csi.c Before I had 2 times format match error but I added to the mx6s-csi {
.name = "RAWRGB10 (SBGGR10)",
.fourcc = V4L2_PIX_FMT_SBGGR10,
.pixelformat = V4L2_PIX_FMT_SBGGR10,
.mbus_code = MEDIA_BUS_FMT_SBGGR10_1X10,
.bpp = 1,
} and added to mxc_mipi-csi.c {
.code = MEDIA_BUS_FMT_SBGGR10_1X10,
.fmt_reg = MIPI_CSIS_ISPCFG_FMT_RAW10,
.data_alignment = 8,
} and v4l2 API works, there is no error. Below my command to get picture v4l2-ctl -d /dev/video0 --verbose --set-fmt-video=width=1920,height=1080,pixelformat=BG10 --stream-mmap --stream-count=1 --stream-to=bb001.raw and the result with my debug messages mxc_mipi-csi 32e30000.mipi_csi: in function: mipi_csis_s_power

VIDIOC_STREAMON returned 0 (Success) After that nothing is going to happen, just waiting and waiting and nothing. I can not observe any traffic on MIPI DATA and MIPI CLK lines by 20MHz oscilloscope. (I know the bandwidth is low but for data lines there should be anything seen - any change but there is completely silence) Im not sure if clk node is correct and maybe there is no match &clk node with mipi_csi clocks by clock names. Has anyone experience with it? What can I do ? i.MX 8M | i.MX 8M Mini | i.MX 8M Nano Re: Camera sensor os02g10 MIPI CSI for IMX8MM Hi, you can use our linux upstreamed driver, we have tested this on i.mx8mp based debix platform. Here is our driver https://web.git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=263d0fa1d46ac1ae2eebc5a5490fec58233c69ad Here is our DT https://web.git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=a4d0f0c88ae8185315afbc1eb68c978ed710f759 -- Rutvij SiliconSignals Re: Camera sensor os02g10 MIPI CSI for IMX8MM I got it to work. .bpp has to be = 2 but main issue was with hardware
