SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.

bug in SW's make.exe (v3.81) : "Malformed target-specific variable definition" error

Well, after more investigation, I see that the problem comes from an exotic folder name (_STM32_ surrounded by three “=” which I can’t reproduce here due to formatting codes) !
So no problem with make 3.81 if paths have no fancy names... just letters, numbers and _ .
Sorry to bother !


Hi Xavier

OK, now I understand: an ‘=’ in the right-hand side of a dependency in a Makefile define a target-dependent variable, whose name is the left-hand side of the equal sign and the value is the right-hand side of the equal. This variable will be valid only when executing commands to build the current target (what is on the left of the ‘:’) or one of its dependencies.

The problem there was that K:/ is definitly not a valid variable name... If it had been, you will not have had the error, but the build will have failed for another reason, as a dependency would have missed for your target...

So, it’s right: avoid fancy folder names, and especially always omit ‘=’ signs in a folder name (by the way its the first time I see such a folder name...)
