Simple non-Rose RealTime program on target
An easy way to test the toolchain functionality is to create a simple
program that prints out “Hello World” on the console.
This program should not use any TargetRTS code or libraries. Compile
and link the program outside of Rose RealTime using your toolchain,
and download the executable to the target. If it executes successfully,
then your development environment is ready.
Further testing is strongly recommended. This would include some
basic RTOS services such as thread creation in your test program.
Again, no TargetRTS code or libraries should be used. Many RTOSes
provide example programs to compile and run. Try these out and verify
the functionality of your setup. If you are using a source-level
debugger, verify that you can step through the source code and
examine variables. If the debugger is aware of operating system data
structures, check if you can examine these. Another important test for
C++ compilers is to include a static constructor in the test program.
This will ensure that proper initialization is performed. The purpose of
this testing to ensure that all of the required operating system features
are operational and understood before attempting the port of the
TargetRTS.
Target Observability TCP/IP support is required. This includes device drivers in
the board support package for the ethernet hardware on the
target. If not provided this is a substantial do-it-yourself
project. Target Observability can be removed from the Targe-
tRTS via configuration options.
new, delete
The RTOS must support some sort of memory management.
In general, this is hidden from the user by the compiler as the
RTOS resolves the new and delete symbols.
main() function Some RTOSes have their own main function defined. If so,
then the main function in the TargetRTS must be redefined.
