Before you could run the "demo.elf" file on MicroBlaze you should configure the "stdio output".
You shoud click "Run">"Run Configurations...".
|
A pop-up "Run Configutations" will appear. Click "demo.elf" (if it is not already selected) and then click "SDIO Connection" tab.
 |
Check (
) the box "Connect STDIO to Console" and select as port "JTAG UART". Then click "Apply" button.
 |
Then click "Close" button. The pop-up will close.
| The Debug operation normaly share these settings, so you doesn't need to repeat this procedeure for debug operation but is better to check the settings (it is better to be on the safe side). |
To change perspective you should click "Window">"Open Perspective">"Debug".
The new perspective is the following.
| Demo program (running on MicroBlaze) will work even in case the UART port is left unconnected: it is not necessary to use a USB/Uart converter or Uart port on a PC, if you are using XMD UART HDL block. |
With this application, you can test the PC ↔ USB ↔ JTAG ↔ FPGA communication using a simulated UART (XMD_UART) on JTAG/USB connection.
If you want to input some characters to the XMD UART, then open some terminal emulators,such as
Connect using the following settings:
The UART settings are:
 |
The UART port will output something of tis kind:
Before running the demo application, open the #project_root#\xmd.ini file:
1.rst
2.dow sw/test_hw.elf
3.#dow sw/demo.elf
4.run
5.terminal -jtag_uart_server 4321
To run the demo application
uncomment line 3 (remove "#")
comment line 2 (add "#" as first character)
save xmd.ini.
type "exit" in XMD command window
restart XMD by clicking again the "Start XMD" button in the XPS toolbar.
With this application, you can test the PC ↔ FPGA communication using a provided API.
