Readme - Hello World Software Example DESCRIPTION: Simple program that prints "Hello from Nios II" REQUIREMENTS: This example will run on the following Nios II designs, targeting the Nios Stratix & Cyclone development boards: - Standard - Full Featured - Fast - Low Cost The memory footprint of this hosted application is ~69 kbytes by default using the standard reference deisgn. For a reduced footprint version of this template, and an explanation of how to reduce the memory footprint for a given application, see the "small_hello_world" template. PERIPHERALS USED: This example exercises the following peripherals: - STDOUT device (UART or JTAG UART) SOFTWARE SOURCE FILES: This example includes the following software source files: - hello_world.c: Everyone needs a Hello World program, right? BOARD/HOST REQUIREMENTS: This example requires only a JTAG connection with a Nios Development board. If the host communication settings are changed from JTAG UART (default) to use a conventional UART, a serial cable between board DB-9 connector and the host is required.
