As an exemple, the following part of makefile does not execute the same way on two successive build launched from “external build”.
It’s like if the $(shell...) command was not reliable when used from stm32 workbench.
Notice that exactly the same makefile source launched from cygwin works very well ...
...

On two successive launch this could give the two differently erroneous results :
First launch result:
