How do I configure the HEAP to be placed within the external memory?
I'm using an LPC1778 with 2MB external memory. I want the controller to calculate an a*-algorithm on a bitmap (loaded from sd-card). Thus, i need lots of dynamically allocated memory (by malloc/realloc).
While searching the forum i only found this: http://www.keil.com/support/man/docs/armlib/armlib_CHDJHFGB.htm .
Can anybody tell me how and where to set the __heap_base to 0x80000000 and the __heap_size to 0x100000?
