Hi Friends,

I am doing a Jtag Programming for SPARTAN FPGA using ARM.
I just gone over the algoritham of XILINX JTAG programming.
The algoritham is made into a program and just it is toggling of pins.

The hex file for the FPGA is get through the UART and sending as a bit 
stream to the FPGA JTAG pins.But my program is not working in the FPGA.
What ever the program i am downloading has no effect.

Does any body tried this features in ARM.
I should make this concept to work out in FPGA.

Any comments over this concept plz post in this group.

with regards,
Rajender
