Hello MY
In MQX 4.2, this working set (“build_libs.uvmpw” for UV4 or “build_libs.wsd” for CW) does not exist anymore, it is only available for MQX 4.0. In MQX 4.2, you should import every library (bsp, psp, mfs, shell, etc) individually.
I have migrated AN4523 SW for MQX 4.2 and created a new project (it is attached) but this was made for CodeWarrior however, it shouldn't be difficult to migrate it to KDS.
I hope this can help you.
If you have another doubt please let me know it.
Best Regards,
Isaac
