Other Parts Discussed in Thread: ALP

Dear Team,

Component name : DS90UB954-Q1EVM

I have EVK kit 954(de-ser) and SER-935.  I Need to take eye diagram for 954.

In 954 EVK have taken the CMLOUT line using a differential probe TP16 &TP17. I could not able to run the CMLOUT Code. its showing "Error WriteI2C not defined". May i know how to proceed on this further?

    Hello,

    Thank you for your question. The ALP scripting interface uses a different format to configure device registers. The proper format for reads and writes within ALP is:

    board.ReadI2C(device I2C Address, register address)

    board.WriteI2C(device I2C Address, register address, register data)

    So for example, the command "board.WriteI2C(0x7A, 0xB0, 0x14)" will set register 0xB0 to 0x14 for the device with an I2C address of 0x7A.

    To update your script to run properly, first update all "WriteI2C" to "board.WriteI2C" then add the appropriate I2C address being used by your specific EVM so that the above format is used.
