Hello,
I'm using a LPC 4357 Board with LPCLink2 and LPCXpresso.
I am using big chunks of data, that have to be processed which means that SRAM isn't sufficient anymore. I read some topics here that it is possible to move the heap-array into SDRAM.
I tried this by adding these two lines to the linker options:
--defsym=__user_heap_base=0x28000100
--defsym=_pvHeapLimit=0x280FFFFF
But when I increase the heap size, I receive a linker-error which refers to RAMLOC32. So my definitions don't seem to work. Has anybody any idea why? Is there anything else that has to be considered?
Kind regards,
Simon
It would be most helpful to attach/include output from the build console and LPCXpresso IDE version information. For now, here are some pointers.
Heap allocation/checking in Redlib
Also, questions regarding LPCXpresso IDE are better posted into the dedicated LPCXpresso forum.
Yours,
