Communication and Configuration
The C10LP RefKit board uses a single chip to perform configuration of the device and
communication over USB.
3.3.1.1
JTAG Chain Configuration
There are two types of configuration methods supported by C10LP RefKit:
1.
JTAG Configuration:
configuration using JTAG ports. JTAG configuration scheme allows you to
directly configure the device core through JTAG pins (TDI, TDO, TMS and TCK pins). The
Quartus Prime software automatically generates a .sof that can be downloaded to the Cyclone
10 LP with a download cable through the Quartus Prime Programmer.
2.
Configuration from EPCQ-A flash:
configuration using external flash. Before configuration,
you need to program the configuration data .jic into the configuration flash memory (EPCQ-
A) which provides non-volatile storage for the bit stream. The information is retained within
