- switch back to MSP stack before starting the scheduler so that the sheduler can use the IRQ stack (when/if needed). - call the C portable function in heap1 to claim some stack back (the number to claim is taken from linker file). - start the scheduler from reset vector (I move this here from main because it make sense to not go back to C (so that I don't need to copy the rolled stack in case the sheduler returns). This make it more clean. - Also I have added the call to the mem manager if sheduler return. that way, we don't reset indefinitely if memory runs out. We will go to this handler and figure things out (right now, it's just looping but at least not rebooting. Probably trap NMI would be better (later improvement). The part missing for this part is the weak attribute for the function in heap1.c so that we don't have to update everything with empty stub. I think the weak atrribute for C function called in assembly is arch dependent so I am not sure if this is possible (will look into it, maybe somebody outthere nows). Right now, it's heap1 dependent and won't work with heap2. I will clean that up the next couple of days. I did some test and it looks good. this is without init code re-organization so we don't free as much as we will be it's good starts. This compile with sim_posix (since it does not affect portable code) so this is really clean. I only tested this with CC. I will port it for OP when I will work on heap2.
Each real time kernel port consists of three files that contain the core kernel components and are common to every port, and one or more files that are specific to a particular microcontroller and or compiler. + The FreeRTOS/Source directory contains the three files that are common to every port - list.c, queue.c and tasks.c. The kernel is contained within these three files. croutine.c implements the optional co-routine functionality - which is normally only used on very memory limited systems. + The FreeRTOS/Source/Portable directory contains the files that are specific to a particular microcontroller and or compiler. + The FreeRTOS/Source/include directory contains the real time kernel header files. See the readme file in the FreeRTOS/Source/Portable directory for more information.
