I've Xilinx FPGA with fixed possibility to configure. So, I wanted to configure that FPGA via JTAG.
Is it possible to use GPIO pins as JTAG pins, such as TDI, TDO, TMS, TCK. And how could I do?
Any advice and suggestions will be greatly appreciated.
If you wish you can implement JTAG on GPIF state machine to program FPGA via FX3.
The other easy way is to program FPGA from FX3 via SPI. Please check the following App note.
Thanks & Regards
