PolyMCU is one of our Open-Source projects. It unifies MCU Vendor SDKs into a single source tree.
We recently updated it to use Nordic nRF5 SDK 11.0.0. Unfortunately, we only have the Nordic nRF52 Pre-DK to test it. It is a call for testers!

Cover the port of STMicroelectronics's STM32 Nucleo L4 to PolyMCU. ST support was not present in PolyMCU before this exercise...
Let's see the encountered difficulties during the port and how we solved it.
Short in memory space on your tiny micro-controller, mysterious build errors, etc. Have you considered updating the toolchain you downloaded few years ago?
This article demonstrates how the toolchain version can affect your firmware.
