I was wondering if someone knows enough about the jtag protocol ... because i would like to something with the usb blaster clone code http://www.sa89a.net/mp.cgi/ele/ub.htm
( version 6 with 18f2550 is working ok for me)
The thing i want to do is the following:
i want to capture the incoming data used to program the cpld (from the sof) and store it in a memory or retransmit it to a remote point via bluetooth to reprogram wire unaccesible fpga on an installation 200mts away...
as a first step i was thinking about faking a cpld to the usbblaster interface by bypassing and doing something with the pic firmware ... but still no success as long as i have no complete reference of altera's jtag
do you have Any tip/ suggestion / don't do that info to share?
thanks in advance
