Post TP2850 driver on i.MX8M Plus

[simonlin]

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?

Do you have any advices?

Device tree setting should be related to your issue.

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]

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]

That means your tp2850 driver has issue. 

[simonlin]

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
