JTAG and USB connections
Two types of connections are available:
- USB connection (USB (host computer) ↔ USB (TE USB FX2 module))
- JTAG connection (normally a JTAG adapter cable; we recommend using the Xilinx Platform Cable USB (USB (host computer) ↔ JTAG (TE USB FX2 module)) ;
Xilinx EDK/SDK and iMPACT (or equivalent XMD console commands) could be used to develop/generate an FPGA bitstream (with MicroBlaze's processor and software "merged" into an FPGA bitstream). When the FPGA bitstream is ready, either the USB or JTAG connection could be used to write the SPI Flash memory of the TE USB FX2 module (i.e. download the FPGA bitstream into the SPI Flash memory).
The JTAG connection could also be used to directly download the FPGA bitstream into the FPGA without the need of a reset.
The JTAG connection could be used with Xilinx EDK and SDK GUIs for development and debug purposes; XMD console could also be used.
The USB connection CANNOT be used with Xilinx EDK and SDK GUIs for development and debug purposes. The USB connection should be used after the development and debug process.
With a JTAG connection, the development and debug phases are easier.
Without a JTAG connection, the user/developer should create/use custom functions/programs for the debug phase but some JTAG debug features may not be easily replicated through a USB connection.
