Hey...
i hope there is a clever guy reading this channel and using Protel....
i have buyed a 3rd party FPGA board with a SpartanII SX2S300E...
There is onboard Jtag (normal Xillinx Jtag)
But when i want to use it with protel and use soft instruments etc...
i have to connet "2 Jtags" at one time, one for the Hard Jtag to program the
FPGA and one to normal I/O Pins... Quite easy just a multiplexer... but...
Their owm Nanoboard has some kind a multiplexer so both chains can be
selected at the same time...
www.altium.com/learningguides/ AR0130_PCToNanoBoardCommunications.pdf
i also hae the schematic here....
I can see on the schematic there is 2 parellel jtags in the parellel cable..
but i can't use the 2'nd as it is... but even more there is a mode and a
control bit i dunno if i can do something m,ultiplexing with...
Any one haveing a solution exept buying their board ?
Regards Kasper
