CubeMX fails to load IOC file after enabling RAMCFG

[Mikk Leini]

There's a bug in latest STM32CubeMX v6.16.1. When enabling RAMCFG for Appli on STM32N6 MCU, the IOC file becomes unloadable.

I attached the demonstration IOC file. I created new project for STM32N6570-DK board, enabled RAMCFG peripheral for Appli, checked the AXISRAM3-6 areas, defined single continuous area for those SRAMs in MMT and saved the project. After this CubeMX fails to load this IOC file. I get popup:

In textual form the error is: Cannot invoke "com.st.microxplorer.mcu.memorymap.MemoryMapService.getInRangeAppRegions(long, long, com.st.microexplorer.mcu.Context)" because "this.mMemoryService" is null.

The workaround is to not enable RAMCFG in CubeMX, rather control the peripheral manually.

Hello @Mikk Leini 

Thanks for posting in STCommunity!

Was your project created with version 6.16.1 or was it migrated from an ancient version of CubeMX?

Attached is a brand now project created today morning to rule out any other cause for the issue.
