15. Firmware Upgrades
The SMT310Q' series carrier boards are populated with two Xilinx CPLDs
(XC95144XL and XC95288XL) that act as an on-board arbitration unit that control
which device has access to the Local Bus resources. These devices are very
important on the carrier board, and it is necessary to keep these devices up-to-date.
From time to time, Sundance might issue a CPLD update. The Sundance wizard
will alert you when you need to update your CPLD.
To upgrade the firmware, Xilinx JTAG programming software is required together
with a lead to connect to the SMT310Q’s header. The image below shows the
location of pin 1 of the JTAG connector J21. This connector is a (2×3) 2mm pin
header.

There are 4 things you require to update the CPLDs on a SMT310Q:
• The Xilinx IMPACT software tool. If you do not have IMPACT, you need
to download the software package from Xilinx called Xilinx Webpack . It is
free and it includes the Xilinx IMPACT tool that will allow you to
reprogram the CPLDs on the SMT310Q carrier board.
• The JTAG programming cable (Parallel Cable IV)
The Parallel Cable IV can be order on Xilinx Website .
