LPCXpresso/MCUXpresso: How guarantee a certain stack size

brampeeters — Thu, 21 Dec 2017 17:22:23 GMT

I was looking into information about how to set a certain stack size using LPC/MCUXpresso when i saw the following thread: https://community.nxp.com/message/767676

Now if I understand things correctly, the idea here is that the linker/toolchain will just use whatever is left and give that to heap and stack.

Since I believe this way of working is incredibly insecure, I want to be able to set a stack size (and potentially heap size though i my current project i am not using a heap) and get a linker error if stack+heap+data does not fit anymore in the available memory.

Is there any info/examples on how to modify the linker templates to realize this ?

Hi Bram Peeters,

Thank you for your interest in NXP Semiconductor products and 

for the opportunity to serve you.

I'd highly recommend you to adapt the heap or stack size by referring to the 11.9 section in the attachment.

Hope this helps.

Have a great day,
TIC
