I'm dealing with FM4 MB9BF56xR Family and I'm using Keil free license as IDE Tool.
The keil free licence allow to compile up 32KB of code.
What is in your opinion tyhe best IDE for designing with FM4 microcontroler?
Do you think exist some tool based on Eclipse as for other microcontroler family (for example STM32 micro)?
There is no Cypress provided IDE for FM4 family. It is supported in a variety of third party IDEs such as IAR Embedded Workbench, Keil µVision, iSYSTEM winIDEA and GCC makefile. For more details, you can refer to https://www.cypress.com/products/fm4-32-bit-arm-cortex-m4-microcontroller-mcu-families
