Post TP2850 driver on i.MX8M Plus

Hi All

I try to post TP2850 on i.MX8M Plus

TP2850 created link to mxc-mipi-csi2.1, and registered mxc_isi.1.capture as /dev/video1 as below

[ 8.616588] mx8-img-md: Registered mxc_isi.0.capture as /dev/video0
[ 8.634974] mx8-img-md: Registered mxc_isi.1.capture as /dev/video1
[ 8.641319] mx8-img-md: Registered sensor subdevice: tp2850_mipi 2-0045 (1)

[ 8.678323] mx8-img-md: created link [tp2850_mipi 2-0045] => [mxc-mipi-csi2.1]

I use below command to record raw data but fail

mx8_v4l2_cap_drm -cam 1 -d "/dev/video1" -fmt YUYV -ow 640 -oh 480 -of
(v4l2_setup_dev:1138): channel[0] VIDIOC_S_PARM failed ret = -1

So I check imx8-isi-cap.c and imx8-mipi-csi2.c

mxc_isi.0 is mepty on my system, is this related to my tv driver fail?

Can anyone provide some advices?

From the attached device tree, I can't find which I2C bus are the two TP2850 connected, and how about the hardware I2C connection for them?

simonlin · ‎03-08-2021

Hi @qiang_li-mpu_se

My OS is android10.0.0_2.6.0

I mount two TP2850 on I2C3 as attachment freescale.7z

Hardware I2C connection is OK, I can read chip ID from register by I2C, log file as attachment teraterm_TP2850.7z

I also try the test application "mx8_v4l2_cap_drm", but get ioctrl error

qiang_li-mpu_se · ‎03-08-2021

That means your tp2850 driver has issue.

simonlin · ‎03-16-2021

Hi @qiang_li-mpu_se

I take the ov5640.c for reference that in NXP bsp , then modify TP2850

The ioctrl function work well

I still try this command--> mx8_v4l2_cap_drm -cam 1 -d "/dev/video1" -fmt YUYV -ow 640 -oh 480 -of

It show -EINVAL when run mxc_isi_update_buf_paddr, because memplanes is 0

But I check YUYV output format as below, the memplanes should be 1
{

.name = "YUYV-16",
.fourcc = V4L2_PIX_FMT_YUYV,
.depth = { 16 },
.color = MXC_ISI_OUT_FMT_YUV422_1P8P,
.memplanes = 1,
.colplanes = 1,
.mbus_code = MEDIA_BUS_FMT_YUYV8_1X16,
},

Finally it run mxc_isi_cap_streamon and start capturing, but 0.YUYV file size is 0, I think it's releated above issue

Do you have any advice?

Thanks

"memplanes 0" means no memory to use, so no video will be captured.
