FPGA Programming using EPCQ
The low-cost ECPQ device with non-volatile memory features a simple six-pin
interface and a small form factor. The ECPQ supports AS x1 and x4 modes.
By default, this board has a FPP configuration scheme setting. In order to set the
configuration scheme to AS mode, resistor rework needs to be done. Configure the
MSEL setting using the MSEL DIP switch (SW1) to change the configuration scheme.
Figure 2–5 shows the connection between the EPCQ and the Cyclone V E FPGA.
Status Elements
The development board includes status LEDs. This section describes the status
elements.
Table 2–7 lists the LED board references, names, and functional descriptions.
