It is also possible to connect another Sundance carrier to this connector. For
example you may connect the JTAG output of an SMT310Q to the connector JTAG1
of the SMT145. In that case the TIMs plugged on the carriers connected via JTAG
are in the same JTAG chain.
The connector JTAG2 provides a JTAG output. It is used to connect different carrier
boards in the same JTAG chain. For example you may connect the connector JTAG2
to the connector JTAG1 of another SMT145 or to the input JTAG connector of a
SMT310Q.
Code Composer Studio drivers are available from Sundance, Part Number
SMT6012 .
JTAG for the SMT145
The FPGA and the PROM of the SMT145 are in the same JTAG chain.
The connector JP6 is used to access these components.
Configuration of the FPGA
When the SMT145 is powered up the FPGA is configured with a bitstream stored
inside the on-board PROM. The bitstream is loaded in the PROM via the JTAG
header
JP6 .
It is also possible to configure the FPGA directly using the JTAG header JP6.
Software Xilinx iMPACT is used for the configuration of both devices.
Software
The diagram shows functionally how the SMT145 works. The host accesses a
number of communication resources via the PCI bus. All communication resources
are presented as X-Link software interfaces, and are memory mapped in the memory
space of the host processor.
