Hi
The document said, "...Prior to MQX RTOS 4.0, the PSP and BSP libraries had to be built before the other libraries. This is no longer required..."
My understanding is: In old version, for example MQX 3.8, we have to build PSP and BSP first, then build other libraries (RTCS, mfs....).
In MQX 4.2, you do not need to build psp and bsp first, you can build RTCS, mfs first. But BSP and PSP is a must. you need to build them before you build your application.
