• Open the project by double-clicking on the system.xmp file. The Xilinx Platform Studio is opened.
• If you open the project with a new version of Xilinx XPS, the tool will try to update all the components of MicroBlaze system. In some case it is not possible to refuse the update.

• Select "Project" > "Select Elf Fle..."
• Select the Efl file demo.elf
• Select "Device Configuration" > "Update Bitstream"
• Select "Device Configuration" > "Download Bitstream"
• Configure Jtag_Uart using "Debug" > "Debug Configuration"
• Run XMD console using "Debug" > "Launch XMD"
• Run ClearTerminal Console

???? If the HDL design was successfully implemented and downloaded to the TE0300/TE0320/TE0630 family module, you can proceed to compile the MB software. Press the "build all user applications" button. ??????

3) Run the demo project

Case A) Use the demo project with the XMD UART

...

With this application, you can test the PC ↔ USB ↔ JTAG  ↔ FPGA communication using a simulated UART (XMD_UART) on JTAG/USB connection.

...

The UART settings are:
bits per seconds: 115,200
data bits: 8
parity: none
stop bits: 1
flow control: none (otherwise you will not be able to enter commands)
The UART port will output something of tis kind:
-Entering main TE0300 DEMO ver 0x07010218-
Setting up Interrupt Controller:
Initialize exception handling
Register external interrupt handler
Register I2C_SLAVE interrupt handler
Enable interrupts in the interrupt controller
Start the interrupt controller
Enabling and initializing instruction cache
Enabling and initializing data cache
Type:
'a' RAM test
'f' RAM Ftest
'c' toggles caching
'g' prints switches state and board revision
't' starts TX transmission 'r' starts RX transmission
's' stops all transmissions
'm' for the redraw menu
MicroBlaze will work even in case the UART port is left unconnected.

PLACEHOLDER STOP

Case B) Use the demo project without the XMD UART

To use the demo project without the XMD UART, you need to use "RS232" instead of "debug_module" as standard in/out port. Otherwise the application running on the Microblaze processor freezes if you disconnect the XMD. To accomplish that you need to set up the Microblaze "Software Platform Settings".

...
