Everest-CortexM1-Demo
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.
