Part Number: TDA4VM

Hi TI members:

Becuase our customer board use DS90UB936 deserializer,

Right now we try to debug the communication between DS90UB936 and TDA4 CSIRx port0.

For TDA4 Vision_apps capture request,

We need to generate 1920x1080, RAW12, on one CSI lane and CSI speed is 1.6Gbps.

Can someone help to check my configuration

i2cset -y -f 5 0x3d 0x1f 0x00 /* Lane speed set to 1.6Gbps */
i2cset -y -f 5 0x3d 0x20 0x30

Hi Chen,

Can you try add below configuration in your test setup? Also please make sure to start CSI only after node is created.

WriteI2C(0xB0,0x00) # Indirect Pattern Gen Registers
WriteI2C(0xB1,0x01) # PGEN_CTL
WriteI2C(0xB2,0x01)
WriteI2C(0xB1,0x02) # PGEN_CFG
WriteI2C(0xB2,0x33)
WriteI2C(0xB1,0x03) # PGEN_CSI_DI
WriteI2C(0xB2,0x2C)

You could even find complete test pattern code under _TEST_PATTERN_ENABLE_ in imaging\sensor_drv\src\ar0233\ar0233_serdes_config.h file.

Regards,

Brijesh

Hi Brijesh:

Thanks for your reply,

I would modify my parameter's value by follow ar0233_serdes_config.h file and try again.

Hi Brijesh:

I find there is one question about ar0233_serdes_config.h define.

1. ACTIVE Line big than TOTAL Line.

In ar0233_serdes_config.h, it will set active_line as 1280 (define in iss_sensor_ar0233.h) and total_line as 1050(0x41A)

 53     {0xB1, 0x08, 0x10}, // PGEN_ACT_LPF1
 54     {0xB2, AR0233_HEIGHT_HIBYTE, 0x10}, //
 55     {0xB1, 0x09, 0x10}, // PGEN_ACT_LPF0
 56     {0xB2, AR0233_HEIGHT_LOBYTE, 0x10}, //
 57     {0xB1, 0x0A, 0x10}, // PGEN_TOT_LPF1
 58     {0xB2, 0x04, 0x10}, //
 59     {0xB1, 0x0B, 0x10}, // PGEN_TOT_LPF0
 60     {0xB2, 0x1A, 0x10}, //

In normal, Active Line should small than Total line.

Can you help to check this config again?

Hi Chen,

That's ok, please update the size that you require..

You could even find pattern generator settings in Board_FpdUb960PGCfg0/Board_FpdUb960PGCfg1 in file \pdk_jacinto_07_00_00\packages\ti\board\src\devices\fpd\ds90ub960.c..

Hi Brijesh:

I just follow ds90ub960.c config to charge my three parameters of "VBP, VFP, Total Line per frame", other parametes keep origin value.

But I finally can pass vx_app_conformace.out RawImageCapture testcase.

Hi Chen,

You mean it works fine now, are you able to capture color bar images from UB936?

Please close the thread if question is answered.

Hi Brijesh:

==> Yes, we can capture color bar image form UB936 now.

But I see there is still some problem when I use RAW data type on CaptureNode and YUV data type on DisplayNode.

I will close this thread, and discuess with you in origin thread.
