4. Verify there is successful local I2C communication that the script worked by going to the register tab,
selecting register 0x00 labeled I2C_DEVICE_ID, and reading the value as shown in Figure 3-37 . If the value

6. Navigate back to the Scripting tab of the DS90UB954 (or variant) ALP profile and run the
953to954_patgen_YUV_1920x1080p-4Lanes-Working.py script to initialize a pattern generation from 953-
>954. The script may be found by clicking on the "Run PreDef Script" button. If the DS90UB954-Q1 (or
variant) is not using an I2C address of 0x7A (8-bit form), the script should be modified to use the correct I2C
address.
