Lab Tutorials and Demonstration File/Folder Location Question 1. How can I develop the environment speed? Answer: If you develop your project off the C: drive (hard drive) of your workstation, it's dramatically faster than off the network drive. Question 2. We tried to put the project files on H: drive but it got full. We tried to save on desktop, but the filenames have a space in their path (Documents and Settings) so the tools don't work. For now we are using folders inside C:\temp. Is there a better place to put the files? Answer: You could try an external USB key or you could ask the System Admin to increase the size of your accounts. Question 3. I have keep trying to "Build All Application", but it fails to create any elf file, and even the "mbo_default" folder with the following errors: “ERROR:MDT - standalone () - couldn't open "./src/config.make": no such file. .. “ Answer: Make sure there is no “space character” in the folder path. Question 4. I am trying to run iMPACT but getting an error like “no write permission”. What

can I do now? Answer: Create a shortcut to iMPACT on the desktop (found in C:\Xilinx8_2\bin\nt folder) Right click on the shortcut and select Properties Change the "Start in" properties of the shortcut to a directory like temp that you can write to When it then runs it will ask to change the working directory to the one you specified in the properties Software Debugger Question 5. Whenever I try to connect to the GDB software debugger I get the error message "localhost: 1234: Connection refused.”. GDB cannot connect to the target board using localhost: 1234 though the board is securely connected. What should I do now? Answer: You need to have the XMD console running for GDB to connect on that address/port. XMD acts a server and must be running before you launch the GDB. Commands Question 6. When I type con (continue) command in XMD, it says “Processor started”. After that whenever I type 'stop' to stop processor, it says "Unable to stop processor" and just continue to execute the program until I rst (reset) the system. Can I use the ‘con’ syntax for a faster debugging or I have to use stp (step)? Answer: When you push "stop", GDB sends a signal to interrupt processor execution. If GDB can't communicate with XMD to interrupt processor execution, you get this message. You can just continue execution instead of stepping; however, you should insert an extra breakpoint to stop the processor after you type con.
