When you start a board bring up activity from scratch, there are many challenges. The first of these challenges is the choice of the development environment. Is there any commercial agreement with an IDE Vendor? How flexible is debugging on the IDE and build time, code footprint after optimization etc are related concerns. If the choice is a command line based build environment, the developer is free to choose what features he needs and how easily he can customize it for his requirements.

In case of a Graphical development environment, the IDE takes that decision for you. There are many Graphical IDEs some are commercially licensed and some are available with opensource licenses. Eclipse based IDEs are very famous across the opensource licensed Graphical IDEs.

I was surprised to learn MQX(Ver 4.2) does not support SPI Slave configuration.

Reference

There are many workarounds in the community but the information is in bits and pieces. So i decided to write this note.

I wanted to configure SPI0 Channel on MK64FX512VLQ12 board as Slave driven by interrupt in which can call MQX APIs. I have MQX Ver 4.2 installed.  My base BSP is derived from TWR-K64 board BSP given by MQX. IDE is KDS.f Reference hardware is TWR-K64 board.
