Hi.


--- Quote ---The EEPROM was changed before the OS grade. via the FTDI - FT Prog tool.  There was no test performed to validate the change. The change was made to Hardware Specific/Port B/Hardware to set RS232 UART.

JTAG for port A and UART for port B was predefined. You didn't have to change that.

You used the newest FT_PROG tool from FTDI webpage? This is the problem, in case you has used the newest version. The new FT_PROG seems to have a bug. It didn't not write check sum on the correct address in the EEPROM, like it should be done from the FTDI specification. With older FT_PROG version it works fine.
Do you have some older version of FT_PROG?
