Data Link up, ready for packets at
Transaction Layer (PCI enumeration
of config registers).
L0 training sequences completed,
PHY Layer up and ready for flow
control.
Polling.
PLL locked to PCI Express 100MHz
clock.
16-seg will display states with
letter codes as described below:
I – Initialization; driver is loaded
and initializes the board
O – Open; demo program is run
and driver opens access to board.
C – Close; demo exits and driver
closes access to board.
R – Remove; driver reads that
board is removed from system, as
in uninstalled device.
E = Error; driver detects board
hardware error during initialization.
Blinks to indicate PCIe transaction is
accessing registers or memory in
demo IP. Indicates PCIe bus
transactions.
