Anyone noticed that mbed Studio does not properly recognize the Dragonfly Nano?

Instead of "0312...." it should be getting it is instead getting DEVICE_ID "0310..."

Dragonfly Nano: MTS_DRAGONFLY_L471QG "0312..." Dragonfly: MTS_DRAGONFLY_F411RE "0310..."

I would think any mbed tool will exhibit this same issue.

The solution: If running a Dragonfly Nano you must update the platform (USDK2) with the appropriate DEVICE_ID. Download & Install the following: https://www.st.com/content/st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-programmers/stsw-link007.html

Then run ‘st-LinkUpgrade.exe -force_prog -board -0312’ to program the interface chip on the UDK2 as MTS_DRAGONFLY_L471QG
