To resume,

On cyclone II, (http://www.altera.com/literature/hb/cyc2/cyc2_cii5v1_06.pdf figure 13-25)

JTAG pin 1 connected to FPGA TCK with 1k pulled down.....JTAG pin 2 connected to GND

JTAG pin 3 connected to FPGA TDO..................................jtag pin 4 directly connected to vccio.

JTAG pin 5 connected to FPGA TMS with 1k Pulled UP.........jtag pin 6 no connect (for usb blaster and byteblaster ii).

JTAG pin 7 No Connect....................................................JTAG pin 8 No Connect.

JTAG pin 9 to FPGA TDI with 1k Pulled UP.........................JTAG pin 10 to GND.

Is it right ?

250$ burnt for just one pin :eek: :d
