Newbie level 3
Hello all,
i m a newbie to FPGA world, and i m currently trying to debug an FPGA board made by my company. The details are as follows.
Its has a Cyclone 4 :EP4CE10E22C8N FPGA, a SPI Flash, and user LEDs, DIP switches and push button switches. Programming is through a USB-- JTAG conversion chip (FT2232H)which is directly connected to the JTAG pins of the FPGA. Currently , the FPGA is programmable using "urJTAG", but even a simple program to light an LED is not working once the code is programmed. I need a start as to how to debug this board. Are there JTAG debugging tools available (free), and what is the additional hardware i require to do a debugging of my board.? Will Boundary Scanning be of help, or should i physically start to check all the connections for stuck at 0s or 1s.?
Thanks in advance
