Stepping through the sample application
1.4 Stepping through the sample application
When starting the debugger, you will see the
main()
function (see example screen shot
below). The
main()
function appears as long as project option
Run to main
is selected,
which it is enabled by default. Now you can step through the program.
OS_Init()
is part of the embOS library and written in assembler; you can there fore only
step into it in disassembly mode. It initializes the relevant OS variables.
OS_InitHW()
is part of
RTOSInit.c
and therefore part of your application. Its primary
purpose is to initialize the hardware required to generate the system tick interrupt for
embOS. Step through it to see what is done.
OS_Start()
should be the last line in
main()
, because it starts multitasking and does not
return.
