Application:  hello_uart_1
------------------------
The low level UART driver I/O routines are used to print "Hello World!" to the
COM2 serial port and then continually echo any characters typed on the keyboard.


   CONFIG Switch Settings:  00010101 

1. Connect the Host PC to the ML507 (J1 header) using a PC-IV or
   Platform USB JTAG cable

2. To use the COM2 port on the ML507, you will need a header, Samtec part 
   Number: SSQ-105-02-G-D and a short cable, a DB9M TO IDC10 SERIAL 
   (AT-EVEREX-INTEL Version) PORT. The header can be ordered from DigiKey: 

   http://www.digikey.com/scripts/DkSearch/dksus.dll?PName?Name=SAM1185-05-ND

   The cable can be ordered from pccables.com:

   http://www.pccables.com/cgi-bin/orders6.cgi?action=Showitem&id=ID405088&partno=07120

3. Connect the Host PC serial port to the ML507 COM2 serial port using a null
   modem cable and launch a terminal program on the Host (eg. TeraTerm)
   with the settings: 9600 baud, 8-N-1, No flow control

4. Launch XPS and open the ML507 EDK project (ml507_bsb_system.xmp)

5. Launch a Shell window using XPS menu selection: Project > Launch EDK Shell

6. Download bitstream in shell window by typing: impact -batch etc/download.cmd

7. XPS menu selection: Debug > Launch XMD

8. At XMD% prompt type: cd microblaze_0/code

9. At XMD% prompt type: rst

10. At XMD% prompt type: dow hello_uart_1.elf

11. At XMD% prompt type: con


Serial Port Output:
-------------------
Hello world! Using low-level UART driver
