This Package files helps you to perform a simple test of the uC/OS-II v2.6x Kernel on the Altera NIOS DemoBoard.


# Package's File :
-------------------
   uCOS-II_NiosPort_V22.zip


# Creates a 32 bits NIOS Design :
---------------------------------
   * NIOS32 :
       128/256/512 registers.
       Interrupts and trap enabled.
       Small printf.

   * Peripherals :
       ROM GERMS MONITOR.
       UART for printf (2 stop bits).
       UART for OSView (default parameters) : name="uart_OSView"
       1 TIMER (let default) : irq=17 name="rtos_ticks" ( or set his name in Tasks.h and OS_CPU_A32.s )
       1 TIMER for test (let default parameters) : irq=20 name="timer_for_test"
       256Kb External SRAM.





# installation instruction
---------------------------
   * unzip the file in the sdk's folder created by the sopc_builder :

      \sdk_folder

           -- \inc
           |
           -- \lib
           |
           -- \src
           |
           -- \uCOS-II_NiosPort_V22 (contains Test Port files)

                       |
                       |
                       -- \librtos32 ( you have to copy here uC/OS-II & uC/OS-View ports, 'Makefile' & sources files )
                       |
                       |
                       -- \uCOS-View (uC/OS-View port files + 'Makefile' to build librtos32)
                       |
                       |
                       -- \uCOS-II (uC/OS-II port files + 'Makefile' to build librtos32)
		       |
                       |
		       -- \reference_design (quartus 2.1 project for the demoboard)
                       |
                       |
                   main.c
                   Tasks.c
                   Tasks.h
                   Makefile_nios21 (rename to 'Makefile' if used Nios Dev Kit v2.1 or below)
		   Makefile_nios22 (rename to 'Makefile' if used Nios Dev Kit v2.11 or above)
                   readme.txt (this file)



    building the library:
    * copy uC/OS-II sources files (11) to \librtos32.
    * copy all files except 'readme.txt' \uCOS-II to \librtos32.
    * if you plan to use uC/OS-View, copy uC/OS-View sources files (2) to \librtos32.
    * if you plan to use uC/OS-View, copy all files except 'readme.txt' from \uCOS-View to \librtos32.
      in this case, 'Makefile' & 'includes.h' will have overwritten.
    * Generate the library by excuting the "make" command under \librtos32.


    compiling the application:
    * then, build the main application by a "make" in \uCOS-II_NiosPort_V22 directory.
      (dont forget to rename one of the two Makefiles in 'Makefile')

    --> modify paths to Makefile file if necessary


    ( because uC/OS-View uses the second UART, you have to use it with the Debug RS232 cable )


# Execution
------------
   * after downloading, you will see the messages printed by the 3 Tasks and the ISR...
