Hi,

please refer to DS90UB96X-Q1EVM User's Guide, it has one script for reference in page 22. You can configure every FPD-Link RX port parameters, and CSI port as well respectively.

regarding the pattern generation, you can refer to the example in d/s as well:

你好：
我是按照datasheet配置的Pattern Generator， 测试之后输出的波形如之前的示波器显示， 请问这个波形是否正确？
目前遇到的问题是我这边主设备没有解析到数据， 是哪里有问题， 帮忙分析一下， 谢谢！！

Hi Junqiang Shi：
We used NXP imx6q sabresd here， there‘s some problem. Do you have any experience on this processor?
Have the DS90UB964-Q1 used on this processor before ?

Sure, we have many successful cases for the link debug between UB964 and imx6q.

best rgds,

Hi Junqiang Shi:

  Q1 :In Pattern Generator mode,Now i have Parsed the data,But i Configured with 8 colors bars,now only two colors ,The following figure is my generated image, is it right?

 Q2:In bist mode ,Is not as long as the configuration ds90ub964 0xb3 enable bist mode can open the 913 bist mode?the following configuration is correct?

ret = ds964_read_reg(ds964_sensor_data.i2c_client,0x57);

printk("bist start  err num == %d\n",ret);

ds964_write_reg(ds964_sensor_data.i2c_client,0x10,0xA1);

ds964_write_reg(ds964_sensor_data.i2c_client,0x11,0x81);

       ds964_write_reg(ds964_sensor_data.i2c_client,0x4c,0x01);

ds964_write_reg(ds964_sensor_data.i2c_client,0x58,0x58);

ds964_write_reg(ds964_sensor_data.i2c_client,0xb3,0x05);

mdelay(100000);

ds964_write_reg(ds964_sensor_data.i2c_client,0xb3,0x00);

ret = ds964_read_reg(ds964_sensor_data.i2c_client,0x57);

printk("bist end err num == %d\n",ret);

Q3：Normal mode, fv, lv signal is present but the output is monochrome, no normal display preview, waveform and display as shown below.

Hi Junqiang Shi :
please help me reply this question ,thank you very much!

Hi, please help refer to TI's DS90UB96X-Q1EVM User's Guide, which has one example script for reference.
To configure UB964, you need configure FPD-Link (based on port selection to configure each port), and CSI (also you should select either of the two CSI ports before you configure them).
for your questions:
1. The color display is not correct, you can check the simple pattern gen. firstly to check whether the link between UB964 and i.MX6 is correct or not;
2. In the BIST mode, you can set the register 0xB3;
3. regarding FV and LV, it seems the polarity is NOT same as the default setting of UB964. please check register 0x7C for the correct setting.

regards,
Steven
