JTAG and USB connections
Two types of connection 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)

Both USB connection and JTAG connection could be used to downolad the FPGA bitstream on the SPI Flash (write the SPI Flash content).
- ) ;
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

after the development and debug process.
With a JTAG connection, the development
It is possible to use Xilinx EDK/SDK and Impact (or equivalent console XMD commands) to develop an FPGA bitstream (with MicroBlaze's SW "fused" in FPGA bitstream) and program the TE USB FX2 module without use of a JTAG connection.

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.
