Kria SOM CC FTDI Design Guide¶

AMD designed carrier cards for Kria SOM use a FTDI chip for their USB-JTAG / UART implementation. The carrier card contains a dedicated EEPROM used by the FTDI chip to load its configuration at power-on.

The schematics for each of the AMD carrier cards can be found on their resources tab: KV260, KR260. KD240. A “FTDI JTAG/UART” or similiar section in the schematic will detail the FTDI device and its EEPROM implementation on the carrier card.

The FTDI EEPROM user area guide can be found in FT_000162. The FDTI EEPROM can be programmed such that Vivado hardware manager can recognize the board as a device. Refer to UG908 for more information.

Example Script¶

We have provided an example FDTI programming script that programs the FTDI EEPROM chip on AMD Kria SOM Starter Kits. Download the scripts ftdieeprom.tcl and ftd2xx.tcl. Place them in the same folder on your PC. The PC should have an Vivado installation as that provides utilities required in the script.

In XSDB, cd to the folder containing the script:

source ftdieeprom.tcl
device_list
program_eeprom <Location> <boards> <SerialNumber>

#<Location> is the "Location" printed from the device_list command
#<boards> is from ftdieeprom.tcl list, in this case it can be MLCC, KRCC or KDCC
#<SerialNumber> must be 12 characters

After programming, you need to unplug and re-plug the USB cable for the device_list command to show the updated EEPROM reads.
