3.5.3 Procedure

  1. Open the DS90UB954 (or variant) device window by double clicking the profile and selecting to the scripting tab as shown in #X645.

  2. If you would like to set up a file that loads all of the scripts and creates a button for running each script, consult GUID-9984C171-9F03-42EA-A760-106B1A046720.html. Otherwise, you can run scripts by clicking the Run button and navigating to their file location.
  3. If you would like to place the scripts in the default ALP script folder, move them to the file location:

    C:\Program Files (x86)\Texas Instruments\Analog LaunchPAD 1.56.0010

  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 #X1849. If the value is not 0x7A, then the correct profile has not been assigned to the correct USB2ANY ID. Consult GUID-07AAB36E-F8DD-4B1E-B31A-5FF887F5F39C.html#GUID-07AAB36E-F8DD-4B1E-B31A-5FF887F5F39C for more information.

  5. Ensure that the devices are setup properly by checking that Pass Sts: displays Pass and Linked has a frequency listed like shown in #X2902. In addition, be sure that D3, labeled Lock, and D15 label Pass, are illuminated on the DS90UB954EVM (or variant).

  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.
  7. Verify that the pattern has been enabled navigating to the information tab on the DS90UB954 (or variant), and checking to the horizontal and vertical parameters for the appropriate resolution defined by the camera. #X925 shows 3840 bytes and 1080 lines for the horizontal and vertical parameters, respectively. Also, verify that the DC power supply, the HP E3610, is sourcing more current.
