I think that DISCO-L475VG-IOT01A and nRF52-DK supports CMSIS Framework (see here: CMSIS — PlatformIO latest documentation). But to this date PlatformIO does not support CMSIS Framwork with these boards, am I right ?
Yes, you’re right. At the moment these boards don’t support the mentioned frameworks.
This is not what I said, I said these boards are supporting CMSIS library (CMSIS is for all ARM Cortex architecture), but platformIO does not support CMSIS with these boards isn’t it ?
something intersting in relation with this post: framework-cmsis depends on framework-mbed · Issue #143 · platformio/platform-ststm32 · GitHub
