2. Getting Started
This demo design implements a SFP+ loop based on the Cortex M1 Demo design, offering a
soft processor subsystem with GPIO’s, UART and I2C functionality. Internal SRAM blocks are
used for both, program and data memory. Two UART terminals are operated through USB
connector J9.
The application prints “Hello World” on both terminals. Characters entered on UART 0 are
printed on UART 1 and vice versa. LEDs 1 and 2 are toggled by a software counter in the main
loop, that could be reseted by pressing one of the four push buttons. LED 4 indicates that the
receiver of XCVR lane 0 is ready and LED 3 is on between the transmission and reception of
a frame. Every frame consists of the comma character “BC”, the actual frame counter value
and the hexadecimal representation of the ASCII character and is printed out on UART 0.
2.1 Prerequisites
For the Everest Cortex M1 SFP+ Loop Demo the following is needed:
Item
Quantity
Everest DEV Board

Note 1: The Everest DEV Board offers an on-board FlashPro5 programmer, which can be
used to program and debug with Identify, SmartDebug and embedded application software
using SoftConsole.
Note 2: There are differences between Everest Dev Board PROTO and Rev. A and B
concerning the configuration of the SFP+ interface that are descripted in chapter 3.1.

2.5 Powering up the Board
Insert the Finisar Optical Transceiver into the J1 connector (SFP+ module cage). A loop has
to be built by connecting the transmitter with the receiver with an optical fiber cable. The
Everest DEV Board is powered up using the 12 V DC jack. For programming connect it
although with your computer using USB mini B connector J9.

3. Demo Design
3.1 SFP+ related differences between Everest DEV Board PROTO and
Revision A and B
On Everest DEV Board PROTO the SFP+ signals RX_LOS, RS0, RS1, TX_DIS and
TX_FAULT could only be accessed via the I2C I/O expander PCA9538 that is connected to
the same I2C bus as the SFP+ interface itself.
