DM814x ISS Pattern Generator Test

Intellectual 920 points

Hi all.

Target H/W : DM8127 Ipnc

Software Version : 2.0.0

Using default Image Sensor(MT9J003), HDMI out is OK and PC side streaming also OK.

For some reason i'd like to test the PG(Pattern Generator) block of ISS Module.

So i set the related register like this to make 1920x1080 resolution image :

(1)

isp_regs->ISP5_PG_PULSE_CTRL = 0x077F0437 // HD Width --> 1920-1, VD Width --> 1080-1

isp_regs->ISP5_PG_FRAME_SIZE = 0x08970457 // Frame PPLN --> 2200-1, Frame HLPFR : 1120-1

isp_regs->ISP5_PG = 0x38 // Bit[5:4] SRC_SEL --> Pattern Generator port is selected, Bit[3] EN : Enable

(2)

isp_regs->ISP5_PG_PULSE_CTRL = 0x00100010 // HD Width --> 1920-1, VD Width --> 1080-1

isp_regs->ISP5_PG_FRAME_SIZE = 0x077F0437 // Frame PPLN --> 2200-1, Frame HLPFR : 1120-1

isp_regs->ISP5_PG = 0x38 // Bit[5:4] SRC_SEL --> Pattern Generator port is selected, Bit[3] EN : Enable

and changed the register value many times but there is no HDMi output .

My question is : are there any other register must changed except above 3 registers ?

Thanks in advanced

Best Regards

Hi Hennessy,

When you enable the pattern generator, do you disconnect the sensor module or is it still streaming the data?

Hi Rajat

Thanks for quick response.

The sensor module is still connected to paralled port and it send the signals normally that's because sensor module don't know this test situation.

When enabled the PG module

1) HDMI out is just white and never changed

2) Streaming(PC Side) -- Black and never changed

Hennessy,

Can you dump and send the complete registers for ISIF, ISP ?

A black output could mean that you are not getting any resizer output - this could be because of some configuration mistake.

Below is the dumped register value.

For better understanding, My code is out of box state(Revision 2.0) and i added these code at the start of Iss_captStart() function.

Int32 Iss_captStart(Fdrv_Handle handle)

{

Iss_CaptObj *pObj = (Iss_CaptObj *) handle;

Int32 status = FVID2_EFAIL;

Iss_CaptChObj *pChObj;

    {
        isp_regs->ISP5_PG = 0x3B;
        isp_regs->ISP5_PG_PULSE_CTRL = 0x0437077F;
        isp_regs->ISP5_PG_FRAME_SIZE = 0x0897044B;
        //isp_regs->ISP5_PG_PULSE_CTRL = 0x00100100;
        //isp_regs->ISP5_PG_FRAME_SIZE = 0x077F0437;
    }

* check if global handle, this operation is not supportted

* for global handles

if (handle == (Fdrv_Handle) ISS_CAPT_INST_ALL)

return FVID2_EFAIL;

GT_assert(GT_DEFAULT_MASK, pObj != NULL)

}

There is answer about the question？

1.Why IPIPEIF is disable？when disabled，the data can pass on to IPIPE？

2.whe ISP5_PG enabled，which module the pixel clock come from？

Thanks very much！

Hi all.

Target H/W : DM8127 Ipnc

Software Version : 2.8.0

I added some line in function Int32 Iss_captStart(Fdrv_Handle handle)

isp_regs->ISP5_PG_PULSE_CTRL = 0；

isp_regs->ISP5_PG_FRAME_SIZE = 0x07910877 // the sensor is MT9J003

isp_regs->ISP5_PG = 0x38

I can capture some color bar data，and hdmi is ok 。but about a moment later，the edma stop。
