TO PROGRAM SPARTAN 2 FPGA USING ARM.

2005-10-03 by kumarvdpl

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

Hi Rajender,
 
        I had also a problem programming a SPARTAN FPGA from a serial
EPROM. The problem there was the bit order on the serial line. The EPROM
sends out the MSBit first while the FPGA wants the LSBit first. So I had
to change the bits in the whole FPGA image before programming it into
the EPROM. Maybe you have a similar problem and it works if you change
all the bits before sending the bytes over the serial line. (Bit 8 =>
Bit 0, Bit 7=> Bit 1 and so on)
 
regards
Klaus
