Hello,

I have built a board which has an Altera cyclone IV device (EP4CE10E22C8N). I want to configure FPGA using FTDI (FT2232HL) in JTAG mode. I am having difficulty as my board is not getting detected.

I am using UrJTAG to communicate with the Cyclone IV device. And EPCS4 as the serial memory.

An error is seen when I hit the detect command in UrJtag i.e. tdo seems to be stuck at 0

All the necessary connection as mentioned in Altera Cyclone IV datasheet.

Please let me know if u have any idea where and what am I doing wrong.

Regards,

Saurabh
