Firmware EVAL-CN0428-EBZ

I'm currently trying to get my new CN0428 eval board mounted on an EVAL-ADIUCP3029 answering via my terminal program.

I can enter "help" but there is no response except the echo of the terminal input.

The online documentation states that I have to flash a .hex firmware file on the board but I was not able to find an appropriate file yet.

Does anyone have an idea where to get the file from?

Many thanks in advance!
