Memory management , Heap

[Dev1]

Hello All, 
Please help me. 
I have nrf52840 and added json parser which is large and nested.
Json_parse fails , is there anyway to enlarge heap size?

Any feedback must be useful.

Thanks in advance,

[Håkon Alseth]

Hi,

 

The HEAP size can be adjusted by adding/adjusting the assembler preprocessor define "__HEAP_SIZE=X".

For instance using GCC and Makefile:

ASMFLAGS += -D__HEAP_SIZE=16384

 

Best regards,

Håkon

Hi,

Thanks for quick response,

Once I have tried to add size by changing heap size in  gcc_startup_nrf5*.s  file, but it wasn't help me.
I am going to trying it.
