Have ported the BSP to my platform (K20) and worked through many of the MQX examples, which all work fine.
Now trying to integrate PEG+ into the platform, I have got to the point of building my first GUI application.
But at the conclusion of the make I get a linker error telling me there is no heap allocated.
Warning[Lp012]: no sections with name HEAP included - special symbol HEAP$$Base (referenced from xgetmemchunk.o(dl7M_tln.a)) will be zero.
When I run the code, it drops into MQX-idle at the first point where the new operator is called.
I am using the icf provided with the MQX examples, which (as supplied) has neither stack nor heap. This confused me a bit, since C-stack is usually the first thing set up by the RTL. Therefore I assume that MQX handles stack and heap on its own.?
Anyway, I modified the icf from within IAR IDE to give myself a 64k heap, but still got the same linker error. modified icf attached
What I really want to do is put all the GUI volatile stuff into an offchip SRAM which I have put on the board, leaving the On-chip memory for application stuff. But for now, anything that gives me a heap section would be helpful.
Can you suggest anything? Which manuals should I read?
