Ordering Module_startup [message #536633]

Champs,
I have my own module that does some MMU programming at Module_startup.
This Module_startup needs to be executed before Module_startup of ti.sysbios.heaps.HeapMem but I cant change the code of HeapMem_module startup.
Is there a way to ensure my module startup happens before sysbios HeapMem module startup by making changes only in my Module startup code or the application cfg file without making changes to HeapMem module code.
Regards
Badri

Yes. The Startup module has a list of functions, firstFxns, that are
run _prior_ to running any module init functions.

The startup process is described here:
http://rtsc.eclipse.org/docs-tip/Using_xdc.runtime_Startup

In addition, we've recently added an xdc.runtime.Reset module that
allows modules to add a function that is called before the Cruntime is
initialized; this can be important for some peripheral initialization
such as watchdog timers, CPU clock setup, and some memory/cache
initialization. See
http://rtsc.eclipse.org/cdoc-tip/index.html#xdc/runtime/Rese t.html
