1 How to Build the MIPS_UCOS for Atlas
Follow the 2 steps mentioned in the following lines.

Note: 
1. All references made to <root> must be replaced with actual root of uC/OS-II repository.


1.1 Source code installation
Unzip the mips_ucos_x.xx.zip to the same path where uC/OS-II source was installed (eg. C:\ or /root)

Note: All paths & build reference made to uC/OS-II files are relative. So uC/OS-II source & MIPS_UCOS must be extracted to the same path (So that upon extraction the following folders get created: <root>/SOFTWARE/uCOS-II/mips_ucos & <root>/SOFTWARE/uCOS-II/Ex1_Atlas/)

1.2 Build the executable image

For RAM build on top of TMON (or YAMON):
Run make from the bin folder "<root>/SOFTWARE/uCOS-II/Ex1_Atlas/bin/"

Note: You need to have mipsisa32-elf-gcc tool-chain installed.



2 Atlas Hardware setup
tty 0: It is configured as the CONSOL serial port
	Baud: 115200 Stop bits: 1 Parity: None Flow: None
tty 1: not used

Connect null modem RS232 cables between the Atlas's serial port (tty 0) & a PC COM port.



3 Running the Image on the Atlas
For RAM build on top of TMON:
Follow the "Download procedure for application Images" in TMON.doc to download the executable 'ex1.rec' in the RAM (starting at 0x80100000).

Note: You need to have TMON 1.0 (or later) installed on the Atlas board. For installation instructions refer to TMON.doc



4 PC side setup
Run the Hyperterminal before running the MIPS image.

Starting Hyperterminal (COM1 or some free COM port)
Settings: Baud: 115200 Stop bits: 1 Parity: None Flow: None




5 Settings in build make file
IMAGENAME: Set the project name.

TOOLCHAIN: Set the Tool chain used to build. Choose between cygnus & sde.

DEVPLF: Set the development platform. Choose between linux & windows.
