hello

i am also using cyclone IV device and i am trying to configure my FPGA in jtag mode.

i am using FT2232HL for USB to JTAG protocol conversion.

but when i try to detect my device in UrJTAG console i an receiving a Warning saying

TDO seems to be stuck a 0.

i have checked all my connections 10 times, they all are as per the cyclone IV design guide and Pin connection guidelines provided by altera.

to be more specific here is the link from where i made the connection for the jtag mode of configurations.

"forum banned the link"

i have also give the path for the bsdl file in UrJTAG shell.

i am not able to figure out what is the problem and why is my FPGA not getting detected.

please let me know if you have any idea as yours design seems to work with cpld and fpga.

Regards
