HI:
In my FPGA design, I have a serial port for monitoring service. The question is, how can I re-program the flash memory XC18V01 from FPGA serial port using only the JTAG bus.
Thank so much.

the 18v01 programming docs have neve been released so far :( what you can do is
1) if you have a processor in FPGA with decent c compiler you can recompile the xsvfplayer c code for the processor and use it program the serial rom, but you would also need quit a bit of external ram 2) implement a serial to jtag 'gateway' that converts the seial port into bit toggle of the jtag, then modify the xsvfplayer and make it to use the serial port and your own protocol, in this case the host PC will play the xsvf and send the data to control the jtag pins over serial port 3) you can look at the impact generated .SVF files and re engineer the commands needed to reflash the 18v02 and imlement your own programming algorithmantti
