TE0703-04 - FT232H reprogramming

[p_g_allen@yahoo.com.au]

I used the ftdi FT_PROG utility to enable the Fast Serial Interface Mode and I have reprogrammed some of the e2 that has caused it to no longer work with the Xilinx tools.  I have another TE0703-04 carrier board that still functions properly.  The QR code text on the non functioning unit is 461872.  Is there a solution to this?

Hi,
did you read TE0703 TRM:

• https://wiki.trenz-electronic.de/display/PD/TE0703+TRM#TE0703TRM-USBJTAGandUART

Do not access the FT2232H EEPROM using FTDI programming tools, doing so will erase normally invisible user EEPROM content and invalidate stored Xilinx JTAG license. Without this license the on-board JTAG will not be accessible any more with any Xilinx tools. Software tools from FTDI website do not warn or ask for confirmation before erasing user EEPROM content.

Please send a Email with TE0703 ID Code to: support@trenz-electronic.de
