Initialize the constructors from (in init_bsp.c),

which MQX calls after it

initializes the memory management component.

is the solution that u proposed .

I tried to edit the start up .c but couldn't . eventhough I edited ,saved and build BSP ,PSP and project.

while debugging it again goes to static initializer for cpp which I had commented .

so could u share the steps to edit the startup.c in mqx project and bring it to effect .

I also tried to allocate static heap in linker, can this problem be over come by that method . can u share the steps while using fresscale compiler and ewl lib
