Part Number: ADS4225
Other Parts Discussed in Thread: ADS4222EVM,

Hi, Experts:

I am now using ADS4225 EVM and find that I cannot connect the EVM through USB to my laptop by using ADS42xx/58C28 GUI V2.1.

Then I use FTDI CHIP ID tool to read back the desrciption as below:

While I found I can connect the USB successfully with ADS4222EVM, and the FTDI chip description is below:


 

I am wondering whether the FTDI chip of ADS4225EVM has not been programmed during manufacturing? Is it possible to share me how to program the firmware of the FTDI chip to get the EVM up?

Thanks a lot

Yarn
