IAR 7.50; KW40Z_Connectivity_Software_1.0.1 (KSDK_1.3.0)
If enable graphical stack display from Tool Options...
Got some warnings if set some break points
\platform\devices\MKW30Z4\linker\iar\MKW30Z160xxx4_connectivity.icf
if (isdefinedsymbol(__stack_size__)) {
define symbol __size_cstack__ = __stack_size__;
} else {
define symbol __size_cstack__ = 512;
}if (isdefinedsymbol(__heap_size__)) {
define symbol __size_heap__ = __heap_size__;
} else {
define symbol __size_heap__ = 0;
}...
define block CSTACK with alignment = 8, size = __size_cstack__ { };
define block HEAP with alignment = 8, size = __size_heap__ { };
Should the stack be increase and how much ?
Should de heap remain 0 (zero) ?

Hi Lucian
No, please don't modify heap, Connectivity framework define his own memory manager, refer to the section 3.3. Memory management of the CONNFWKRM.pdf document, as you can see framework provide a non-fragmenting memory allocation solution, where it defines blocks of memorys as:
_block_size_ 32 _number_of_blocks_ 6 _eol_ \
_block_size_ 64 _number_of_blocks_ 3 _eol_ \
_block_size_ 128 _number_of_blocks_ 3 _eol_
When a new buffer is requested to be allocated, the framework returns the first available partition block of equal or higher size.
Hope this information helps you
Have a great day,
