Xilinx ML310 manual System ACE CF Controller, Board Bring-Up

Board Hardware

R

a UART usable with any member of the Virtex-II Pro device family. Please review the EDK Processor IP Reference Guide for more details.

The RS-232 port directly connected to the XC2VP30 is accessible by a 10 pin header(J4). An RS-232 mini-cable adapter included with the ML310 converts J4, 10 pin header, to a DB9 male connector. The adapter is a standard DTK/Intel IDC-10 to DB9 Male. The FPGA RS- 232 port on the ML310 is wired as a DTE and meets the EIA/TIA-574standard

Figure 2-5shows the RS-232 connectivity from the XC2VP30 to the DTK adapter.

System ACE CF Controller

Board Bring-Up

System ACE is the primary means of configuring the XC2VP30 on the ML310 board.Configuration of XC2VP30 is accomplished using the JTAG interface. System ACE sits between the JTAG connector and the XC2VP30, and passes the JTAG signals back and forth between the two. However, when System ACE is configuring the XC2VP30, it takes control of the JTAG signals in order to configure the XC2VP30.
