ADV7180 driver and gstreamer on i.MX515EVK

[VincentChou1z]

Hi!  All,

We wired the ADV7180 EVK to the CSI interface on i.MX515 EVK and try to port the ADV7180 driver into both Linux and Android on the board.  When we linked the ADV7180 driver and it does capture data into memory buffer.  However, when we run gstreamer to test the video buffer, we came across the following error. 

====================

In MVC:mxc_streamon

   case VIDIOC_DQBUF

====================

Does anyone have any experience to fix the gstreamer problem?

Oh I found it. Jump wires was not good idea how to connect the camera. Flat cable with pcb fixed my problem.

In this case you can see errors in D-PHY and CSI2 (ERR1,2) registers.

With MIPI CSI2 2-lanes - wrong connected lanes:

  [ov5640_init_mode] mipi_csi2_dphy_status:0x200

  [ov5640_init_mode] mipi_csi2_get_error1:0x10000010

Correct - both lanes connected:

  [ov5640_init_mode] mipi_csi2_dphy_status:0x300

  [ov5640_init_mode] mipi_csi2_get_error1:0x10

Do you find the solution for the program？

Hi! Daiane,

I searched on the net and discovered that a few people came across the same error!  They obtained the same message:

Error: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0

Do you have any idea why we get this error?

Hello Vincent,

I also have the same error of "ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0".  Can you tell me it you where able to figure out what this error was and how you resolved it. 

Best Regards,

Robert

[RobetAyala]

Hello,

I am having a problem communicating to the ADV7180.  When i run insmod adv7180_tvin.ko, i do not see it returning a probed statement.  Currently i am using the I.MX51 eval kit with an ADV7180LFEBZ eval board.  I have connected the AD7180 to CSI1 port D10-D17, HSYNC, VSYNC, and PIXCLK.  I have also connected it to the I2C1 port on J14. 

Any ideals why I dont see a probe?

Robert

[JohnyHsu]

Dear Daiane,

I've a project using imx.51 with video-in functional.

Would you help to provide how to connected to ADV7180 chipset?

We using a 8 bits data bus to connect to imx.51 CSI1 interface.

But CSI1 interface bus from D8 to D19.

How to connect to these data bus pins?

Connected to imx.51 from D8 to D15 (8 bits) or D12 to D19 (8 bits)?

We need your best help & experience for us.

Thanks a lot~

Thanks for feedback.

Which framebuffer option that you imply need to config it?

We've traced the code, the test program will use 'CSI->MEM' from "ipu_csi_enc.c" which registered a ipu irq "IPU_IRG_CSI0_OUT_EOF" with callback function map to a callback function in mxc_v4l2_capture.c.

Somehow the ipu irq never to be signaled  and never got to get data to queue.

We are figuring out where and why irq go wrong.

[Cyanica]

Hi,

I experienced the same symptoms when I disabled framebuffer support within the kernel config. 

All the best.

Hi! Daiane,

We tried the link but the page is lost.  Could you check the link for us again?  Thanks!

Vincent

[VincentChou1z]

Thanks for your suggestion!  We shall review the unit test code as quick as possible. 

We also suspect the error is caused by the format incompatibility issue.  When we activate the analog video input and save the data in IPU buffer in ADV7180 driver, we save it in YUV422 format.  If we want to play the data in IPU buffer to convert to RGB format and put it in the frame buffer, is there a sequence we should follow to achieve that?

After reconfiguration to :

-STD_NTSC

-8bit colour in CSI_SENS_CONF and csi_param.data_width = IPU_CSI_DATA_WIDTH_8

-pixelformat = V4L2_PIX_FMT_UYVY

-cvbs=1

It can QBUF and look like playing.

But It stopped in dqueue time out below: (Not sure if this is interrupt problem)

static int mxc_v4l_dqueue(cam_data *cam, struct v4l2_buffer *buf){    int retval = 0;    struct mxc_v4l_frame *frame;    unsigned long lock_flags;
    printk("In MVC:mxc_v4l_dqueue\n");
    if (!wait_event_interruptible_timeout(cam->enc_queue,                          cam->enc_counter != 0, 10 * HZ)) {        pr_err("ERROR: v4l2 capture: mxc_v4l_dqueue timeout "            "enc_counter %x\n",               cam->enc_counter);

We use default camera init config except below for NTSC standard config:

//video/mxc/capture/mxc_v4l2_capture.c

static void init_camera_struct(cam_data *cam, struct platform_device *pdev)

{

//cam->standard.id = V4L2_STD_UNKNOWN;    

cam->standard.id = V4L2_STD_NTSC;

....

cam->v2f.fmt.pix.pixelformat = V4L2_PIX_FMT_YUV420;

...

}

Dear Daiane,

I'm primary engineer testing this driver.

I need to brief our HW difference.

-We hook I2C(0x21)  as well as  ADV7180 8 bit data to CSI1(D10-D17) rather than a D10-D19 OVxx camera one of original design) to CSI1(first CSI port) of i.MX515   

-We connect HSync and VSync and Pix Clock to peer of same name of pin but w/o MCLK pin.

-We don't connect power down and reset ping right now.

-We don't connect GPIO input for GPIO interrupt right now( look like we've missed this but mx51_ard.c from ltib-11_01 found only ARD_VIDEOIN_INT_B define but no config code and passing irq to driver)

-We just found default color bit of CSI_SENS_CONF is 10 bit. And trying to fix it by hard code a 8 bit one for our case.

-We use Sony CXD3142R CVBS analog camera signal to adv7180 decoder.

Below is our debug output:

Primary errors below:
mxc_ipu mxc_ipu: IDMAC20's EBA0 is not 8-byte aligned
mxc_ipu mxc_ipu: IDMAC20's EBA1 is not 8-byte aligned

[daiane_angolini]

I don´t think it´s a "gstreamer" problem.

What is NV12? I mean, it´s the video camera output? Does your src pluging support this format?

Why you get a "is not 8-byte aligned" error? It looks like you´re trying to place a wrong format into IPU, Can you double check it?

Can you share your command line? You can double check your plugin capabilities.
