PGA970: Firmware download

Part Number: PGA970
Other Parts Discussed in Thread: USB2ANY,

Hi Scott,

I have few doubts regarding downloading the firmware on to the board.

1. I have successfully downloaded hex file onto PGA970EVM using USB2ANY by uploading hex file FRAM section. But no activities on the board.

     How do I verify whether the hex file is downloaded properly or not?


2. Should I put application specific code under the files pga970_main.c or pga970.app.c?

Looking forward to answer

 

Thank you.

    Hello Shashidhar,

    You will need to check that the register settings of the PGA970 match what was configured in your device initialization in the firmware. Otherwise, you could toggle a GPIO in the code or set a specific DAC code as an output to give you something to measure so you know that the firmware is loaded properly.

    Application specific code can go anywhere you like. I would recommend building your functions in the app.c file, and calling them in the main loop.

    Regards,
