TE0703 has on-board USB JTAG and UART solution based on UART/FIFO controller from FTDI. FTDI EEPROM is pre-programmed with license code to support Xilinx programming tools.
| Warning |
|---|
By careless use of FTDI software tools, it is possible to erase content of the 256-byte user EEPROM without confirmation. As a consequence, user loses the Digilent license stored in the Do not access the FT2232H EEPROM using FTDI programming tools, doing so would erase normaly invisible user EEPROM content and invalidate stored Xilinx JTAG License. On board JTAG would bot be accessible any more from any Xilinx tools. Tools from FTDI website do not ask or warn before they erase user EEPROM. |
Ethernet
On-board Ethernet jack J14 pins are routed to B2B connector JB1. Ethernet jack J14 LEDs PHY_LED1 and PHY_LED2 are both routed to System Controller CPLD bank 1.
