7.4.4 Configuration via JTAG
The TXMC638 provides two JTAG chains which are accessible by one of the following connector options:
User JTAG Chain
x
JST XRS Debug Connector
TEWS Factory configuration Chain
x
XMC Connector P15
The User JTAG Chain is accessible from the JST XRS Debug Connector.
For direct FPGA configuration, FPGA read back or in-system diagnostics with Vivado Logic Analyzer, the
JST XRS Debug Connector can be used to access the JTAG-chain. Also an indirect SPI – PROM
programming is possible via JTAG Chain.
TEWS provides a “Programming Kit” (TA308) which includes a XSR cable and an adapter module that
provides a Xilinx USB Programmer II compatible 2 mm shrouded header
