RAM Overflowed: section `.bss' will not fit in region `RAM'

[faikab]

I just integrated CMock which is part of my unit testing framework and i am trying to test a mocked function however i am running into RAM overflow error. Is there a way to reduce the size of CMock or increase that RAM section which is required? I am using an NRF51422 chip but i also have the NRF51822 available if that makes a difference.

Any help is greatly appreciated! Thank you in advance

Hi,

Do you really need to do the tests on your target HW? We use CMock in our SDK for Mesh, but we run the tests on a host system, like a PC, and not the nRF51.

Here is some documentation: Building the mesh stack

Hi MartinBL,

Just a quick question do you manually create the CMAKELists.txt files or is it possible to automate them somehow?

Hi,

Sorry for not getting back to you.

I talked to the Mesh guys again and as mentioned earlier they do all their testing on a host system, and they don't have the need for testing their code directly on HW. Hence, it is a little difficult for us to help you out in your quest since we are on a different path in this regard. And unfortunately the files are made by hand.
