35 xPC Target 1.2 Release Notes
35-4
Known Software and Documentation Problems
This section updates the xPC Target 1.2 and xPC Target Embedded Option 1.2
documentation set, reflecting known xPC Target and xPC Target Embedded
Option software and documentation problems.
Uploading Data with External Mode
xPC Target does not support uploading data to normal Simulink scope blocks
when using Simulink external mode. Instead, use xPC Target scope blocks or
the xPC Target graphical user interface (GUI).
Target Command Line Interface
Visualizing or changing parameter values is limited to scalar parameters.
Memory-Mapped Devices
Some supported boards in the xPC Target I/O library are memory-mapped
devices. These memory-mapped boards are accessed in the address space
between 640K and 1M in the lower memory area. xPC Target reserves a 112 kB
memory space for memory mapped devices in the address range
C0000 - DBFFF
Some drivers for memory-mapped devices allow you to select an address range
supported by the device, but not supported by xPC Target. For example, the
CAN drivers for Softing allow you to select memory ranges above DBFFF.
Select a memory range supported by both the device and xPC Target.
Selecting a Working Directory Inside the MATLAB
Root Directory
Before you run the command xpctest, select a current directory outside of the
MABLAB root directory.
During the build process, Real-Time Workshop does not allow files to be saved
within the MATLAB root. If you select a current directory within the MATLAB
root, the xPC Target test procedure will fail when trying to build a target
application.
