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 purpose of this example is to demonstrate the smallest possible Hello World application, using the Nios II HAL library. The memory footprint of this hosted application is ~332 bytes by default using the standard reference design. For a more fully featured Hello World application example, see the example titled "Hello World". The memory footprint of this example has been reduced by making the following changes to the normal "Hello World" example. Check in the Nios II Software Developers Manual for a more complete description. In the SW Application project (small_hello_world): - In the C/C++ Build page - Set the Optimization Level to -Os In System Library project (small_hello_world_syslib): - In the C/C++ Build page - Set the Optimization Level to -Os - Define the preprocessor option ALT_NO_INSTRUCTION_EMULATION This removes software exception handling, which means that you cannot run code compiled for Nios II cpu with a hardware multiplier on a core without a the multiply unit. Check the Nios II Software Developers Manual for more details. - In the System Library page: - Set Periodic system timer and Timestamp timer to none This prevents the automatic inclusion of the timer driver. - Set Max file descriptors to 4 This reduces the size of the file handle pool. - Uncheck Clean exit (flush buffers) This removes the call to exit, and when main is exitted instead of calling exit the software will just spin in a loop. - Check Small C library This uses a reduced functionality C library, which lacks support for buffering, file IO, floating point and getch(), etc. Check the Nios II Software Developers Manual for a complete list. - Check Reduced device drivers This uses reduced functionality drivers if they're available. For the standard design this means you get polled UART and JTAG UART drivers, no support for the LCD driver and you lose the ability to program CFI compliant flash devices. 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: - small_hello_world.c: 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.
