Installation: 1. The following error message appears when trying to load a program in BIOScope: Cannot communicate with DSP board. Verify I/O settings and check for conflicts with other boards in your system. Reset the DSP board and try again.

If you have changed the default settings of the I/O map switches on the target board; you may need to define an environment variable. BIOScope goes though the following sequence to locate the board’s I/O address: Checks the command line –p option Checks D_OPTIONS environment variable (TI tools) If no board I/O addresses have been found, it uses the default value of the board. Example, the board I/O address is set to 0x320. You can pass a command line parameter to scope to specify the I/O address of the board. You can include this in a Windows 95 shortcut or invoke scope from the command line, e.g., scope.exe –p 320 Or enter the following environment variable in your autoexec.bat: set S_OPTIONS=-p 320 You can refer to the board documentation for further information on D_OPTIONS. Also, refer to Chapter 1 'Environment Variables' in your Getting Started Guide and the PRODUCT RELEASE NOTES for additional information on environment variables. If the steps described above do not resolve the problem, the hardware might be conflicting with some other board. Check the I/O settings for the other devices in your computer to see if there are any conflicts.
