where to set heap_1, heap_2, heap_3?

Posted by Toan Pham on June 13, 2009

Hi,

I read through the online documentation and looked at some of the demo application and I couldn't find where to set the type of memory manager to use.
how/where do i specify what type of memory model i want to use: heap 1, heap 2, or heap 3.

I am a notice to freeRtos, please help. thank you.

heap_1 is in heap_1.c, heap_2 in heap_2.c, heap_3 in heap_3.c. Include one c file in your project to use that heap.

yeah, i thought so; just that the demo projects i looked at SAM7S eclipse and the SAM7X Rowley did not include those files.

or maybe i was included somewhere that i missed.

When i added heap_2.c, i got duplicate declaration to pvPortFree etc....

I need to include heap_2.c in my webservice.c file to debug the memory manager.

I've looked all the files in the source code and I couldn't find heap_2 included anywhere else.


am i missing something?

You can only have one of heap_1, heap_2 or heap_3 included at any one time. If you ap was compiling already then you must have had one of the three files included already. If you want to add a different heap_x version then you must first remove the version that is being used.
