-For GCC, you will have to swap the CortexContextSwitch.s file with the file CortexContextSwitch.s.gcc which will be located in `/yotta_modules/microbit-dal/source`. For an example of how to do this, look below:
-
-```
-#first rename the existing one
-mv yotta_modules/microbit-dal/source/CortexContextSwitch.s yotta_modules/microbit-dal/source/CortexContextSwitch.s.armcc

-#then rename gcc version so that it is included by cmake
-mv yotta_modules/microbit-dal/source/CortexContextSwitch.s.gcc yotta_modules/microbit-dal/source/CortexContextSwitch.s
