Simple non-Rose RealTime program on target

C++ Porting Guide - Rational Rose RealTime 5

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.
