iMX6, display problem with mipi adv7282-m device source

We success in display first acquisition from adv7282-m device after a problematic start (see https://community.nxp.com/message/830163 message)

 

We use PAL video signal and we test without adv7282 progressive format, and with progressive format (mipi clock is double). In these two adv7282 configuration case, we don't reach to synchronize output display image acquisition.

The ADV7282-M output data is 8-bit YCrCb 4:2:2 format and it uses one lane.

Routing MIPI stream into CSI2 is Ok.

 

But gstreamer command :

gst-launch-1.0 --gst-debug=*:1 -v imxv4l2src device=/dev/video0 ! imxv4l2sink

displays:

163824_163824.pngpastedImage_2.png

 Colors are wrong and there is also a vertical scrolling (see mp4 file). 

 

 

If we try to read some VDOA registers (example VDOA_VDOAC(@21E4000), there is a CPU freeze and watch-dog generates reset.

So we try to have more information in IPU configuration, so we add theses two lines un ipu_capture.c :

#undef dev_dbg

#define dev_dbg(dev, format, arg...) {dev_printk(KERN_ERR, dev, format, ##arg);}

We also set to 1 the DEBUG constant in mxc_v4l2_capture.c file

 


 

We try to compare two hardware management:

 

 

BASE1 OK

BASE2  HS

Hardware

Channel0 CSI0 / IPU0 parallel

Channel1 CSI1 / IPU0 mipi

Linux version

3.14.52 + adv7180.c patch

3.14.52 + adv7282.c driver

LOG file

LOG2_adv7180.txt

LOG2 adv7282-m.txt

Remarks:

Used Linux kernel and root filesystem are the same (only devicetree is different). Some debug traces has been added for adv drivers.

In case of adv7282-m, there is a start the encoder job from drivers/media/platform/mxc/capture/mxc_v4l2_capture.c file.

With adv7280 we don’t know how iMX6 transforms 720x575 acquisitions to 1024x768 output display. There is no trace in LOG2_adv7280.txt file

 

Our current questions are:

 

  •       Is combinaison one lane, mipi IPU0/CSI1 has been use with iMX6 quad plus design?

  

  •       Why with adv7282-m management, we find ‘In MVC:mxc_streamon’ trace with PFS=0x4 (instead of 0x7 as it appears in LOG2_adv7280.txt file, 0x4 is NA depending on Freescale documentation) ?
  •       What are parameters to manage IPU format from MIPI flow?

Hello Gabriel ,

     According to your description, it seems that you need to add 2 patches for ipu display, detailed information is here:

Sample code for iMX6 SabreSD to use MIPI CSI camera with virtual channel 3 

You should use this: L3.10.17_1.0.0_mipi_camera_virtual_channel_3.zip 3.0 KB

Try it please!

Hope above advice can help you!

Best Regards,

Weidong

Hello Sun,

Thanks for your fedback. We try to apply adviced pathes but it don't fix IPU management problem we have.
In fact there is a problem if we use patch from drivers/mxc/ipu3/ipu_capture.c because _ipu_smfc_init force mipi source to 0 (instead of 1 in our case) and changes in _ipu_csi_set_mipi_di function generates no diplay, "VIDIOC_DQBUF failed." error message and timeout (see time-out trace in following LOG).

For the moment, it is not a routing problem with the mipi virtual channel #1. The routing seem ok but in the display we get 4 images from mipi source and a wrong YUV decoding (color are not good).

We try to use linux4 kernel (4.1.29 with sabresd target) from krogoth yocto source.
The only way we examine is mxc_v4l2_capture.c file is not as advanced as file there is in 3.14.52 (yocto-jethro).

We still search why there is a IPU configuration problem to display the mipi flow.
If we set ADV7282-M in free-run pattern to color bars, we also get 4 images in the display. So we think it is not depending on analog harware decoder.


How it is possible to configure IPU format & decoding to adjust mipi flow configuration ?

Best regards,

Gabriel GRANGE

Hello Gabriel,

     I discussed your question with my colleague from i.MX Expert team, Suggestions from him are below :

(1) Don't use gstreamer to preview TVIN video on MIPI port.

Each frame of ADV7282-M's output video is made up of an odd filed and an even field,  there are some issues with gstreamer plugin, so gstreamer can't handle the video correctly.

(2)Only using odd filed or even field in adv7282-m driver.

It means we can close one of both fields, and only output the other to MIPI port, at same time, set resolution to be 720x240 or 720x288

(3) Using mxc_tvin_test to capture video input on MIPI interface

Probobly you need to adjust some source code of mxc_tvin_test, but it's not difficult.

(4) About adv7282-m driver

One of our customers also used samlilar solution, driver in attachments is from customer, not released by NXP, but you can refer to it!

(5) Deinterlace about ADV7282-M's output

MIPI port doesn't know which field is odd or even, so the result of deinterlace is not ideal.

Because we don't have ready-made adv7280-m solution, only give you some suggestions!!

Hope above information can help you!

Best Regards,

Weidong

Thanks for your reply,

We continue to work to solve this problem. We use 'MIPI-CSI2 Perepherical on i.MX6 MPUs, Application Note, Rev. 0, 07/2016 document to check iMX6 registers configurations' document to make checks.

We use adv7282m in progressive mode. 

We still have an acquisition format and synchronization problem in with mipi video flow.

See latest result. We get 8 images (instead of 1) and scrolling down problem.

We use freescale capture tool :

       /unit_tests/mxc_v4l2_tvin.out  -ow 1024 -oh 768 -ol 0 -ot 0

We think there is a special ipu configuration to do. The OV5640 example camera use two lanes (adv7282m uses only one lane).

Extra mipi or ipu synchronization informations to help us will be welcome.

Regards,

G.Grange

From your dumpped IDMAC setting, the data format and bpp setting is wrong, for adv7282m, the input video data should be 16bpp UYVY format.

Are there other parmeter than BPP to verify? When we use this command, PFS = 0xA, this value for this parameter is not documented on imx6 RM.

Is there another command we can try with Freescale unit test?

David

Hi David, the ch 12 is the post process channel, you should check your capture channel, ch 1, this is used for camera capture, and the wrong PFS and BPP are set on that channel.

If the capture data from ch1 is already wrong, change the setting in ch12 has no use.

Thank you for your answer, it is an interesting point of view, from the begining of the project we don't pay attention to this ch 1 trace. In the first log file, we don't noticed the ch 1 settings, only ch 23 and ch 12.

Now, no way to find again this ch 1 settings with the same command.

What is the  linux driver which inits the ch1 settings ?

What is the source file, we have to modify in order to see and inits the ch 1 ?

Hi David,

In linux BSP, you can enable the debug messages in file "drivers/mxc/ipu3/ipu_param_mem.h", function _ipu_ch_param_dump(). Then when you run mxc_v4l2_tvin test application, the IDMAC ch0/ch1 setting will be print out.

The capture data path:

CSI -> IDMAC CH0/1 -> MEM -> IDMAC CH12 -> IDMAC CH21 -> MEM -> IDMAC CH23/27 -> Display

So CH0/1 is used to capture the camera data, then it use CH12 and CH21 for resize and CSC, then use CH23/27 for display. So you should make sure the captured data is correct from CH0/1.

BPP seems to be good (0x3 ==> 16BPP)


What others parameters we have to verify ?
We noticed that EBA0 and EBA1 have the same parameter, is it a problem ?
What about PFS, NPB, have they a good parameter (value for PFS is not documented).

For us, il seems to be a synchro error because image is scrolling.
How we can verify that VSYNC and HSYNC are well decoded by MIPI2CSI bridge?

David

Hi David,

The IDMAC CH1 setting is OK, I had reviewed your old register dump. There are some issues:

IPU1_CSI1_SENS_CONF(@0x2638000)        =0x04000A30   --> YUV422 8 bits per color, CCIR interlaced mode (BT.656)

Note: for MIPI camera, the clock mode should be gated or non-gated clock mode

IPU1_CSI1_SENS_FRM_SIZE(@0x2638004) =0x027002CF  --> row=625-1, width=720-1 

IPU1_CSI1_ACT_FRM_SIZE(@0x2638008)    =0x023F02CF  --> row=576-1, width=720-1 

Note: for MIPI camera, the SENS_FRM_SIZE should be same as ACT_FRM_SIZE, 720*576.

With the above setting, if you can capture 2 camera videoes without scroll, they are correct two fields data, then you just need change the capture IDMAC ch1 to interlaced mode to combine the two fields data into one frame. In file drivers\media\platform\mxc\capture\Ipu_csi_enc.c, function csi_enc_setup():

 case IPU_CSI_CLK_MODE_GATED_CLK:
 case IPU_CSI_CLK_MODE_NONGATED_CLK:
 case IPU_CSI_CLK_MODE_CCIR656_PROGRESSIVE:
 case IPU_CSI_CLK_MODE_CCIR1120_PROGRESSIVE_DDR:
 case IPU_CSI_CLK_MODE_CCIR1120_PROGRESSIVE_SDR:
-  params.csi_mem.interlaced = false;

+  params.csi_mem.interlaced = true;

Thank you for notes.

We verify IPU1_SENS_CONF at init and it is OK, we notice that it changes when apply unit test command.

Is it possible that it is the capture unit test script  which modify the SENS_CONF?

When running mxc_v4l2_tvin test application, the SENS_CONF will be set to wrong value, that means your adv7182 driver hasn't report correct information to mxc_v4l2_capture driver.

Thank you for your explanations. We don't find on our driver ADV7282 how to send the good parameter.

We force the /drivers/mxc/ipu3/ipu_capture.c to set gated clock mode

"cfg_param.clk_mode = IPU_CSI_CLK_MODE_GATED_CLK;"

Then we verify the CSI_CONF when imx6 captures :

The SENS_CONF value seems to be OK.

Our picture always scrolling but something news, we have 8 pictures (4 pictures with old parameters):

What others parameters I have to verify ?

In ioctl_g_ifparm(), please set to followed:

     memset(p, 0, sizeof(*p));
     p->if_type = V4L2_IF_TYPE_BT656;
     p->u.bt656.mode = V4L2_IF_TYPE_BT656_MODE_NOBT_8BIT;
     p->u.bt656.clock_curr = 1;
     p->u.bt656.bt_sync_correct = 1;

After running capture test command, please use "/unit_tests/memtools -32 0x02638000 10" to dump the IPU_CSI1 registers.

The patch is active ("cfg_param.clk_mode = IPU_CSI_CLK_MODE_GATED_CLK;" on ipu_capture.c)

I note that the EXT_VSYNC bit is activated.

What do you think about results?

The reference patch "0001-Correct-mipi-camera-virtual-channel-setting-in-ipu_c.patch" in "Sample code for iMX6 SabreSD to use MIPI CSI camera with virtual channel 3 " is must since you are not using virtual channel 0. You can reference to that patch to set virtual channel 1 or 3 use case.

The default BSP has issue for not 0 virtual channel setting.

"0x02638020: FFFF1EFF " this register is wrong, and IPU_SMFC_MAP register will also be wrong without that patch.
