	You can either use the visual micro project properties to set some extraFlags, there are a few options you will see. These can be for all build sof the project (global) or for the current configuration such as release/debug. or You can redefine the entire pattern by adding a board.txt to the project along with any lines from the build instructions you want to override. If you switch on vmicro>compiler>show build properties you will see the patterns such as the one that include

	sorry for late reply...it did not work since the flags are processed in board.txt.py python code. it seems to add the define "NO_EXTRA_4K_HEAP" define. however, the new version of Wifimanager 0.14 did solve the problem. thanks

	I see, thanks for the update. Yes, if the core you are using does not follow the usual rules and hard codes flags then you would need to tweak the core. Glad it's sorted.

	This seems to be a problem with cores after 2.4.0 To fix it (if you are using WPS) just add the following line to Board.txt in your project (you need to create a Board.txt if you don't have one), no need to run the python script. build.noextra4kheap=-DNO_EXTRA_4K_HEAP
