Board: Nucleo F303RE Mbed Version: 6.2.1 Method: Mbed Studio I’m getting linker errors if I define a std::string inside a loop. Originally I discovered this while trying to allocate a std::string* for try_alloc from a Mail object, but it also happens with non-pointer objects as in this example: v…

Have you managed to solve the problem? What was the solution?

I’m still seeing the issue with the latest patch for mbed-os 6.2.1. My solution was to switch back to 5.15. edit: seems to be an issue for some STM32 boards. When I try to build for various boards (I don’t own them to actually test, I just compiled to binaries): STM32F411: linker error STM32L43…

Hi Seems there is some discussion about this small lib topic in NUCLEO_F303RE with ESP8266 failed to connect WIFI · Issue #13687 · ARMmbed/mbed-os · GitHub

Which JSON did you edit and how did you edit it? I am currently facing the same issue with the 432. Looking forward to your response!

After the last Mbed Studio update (08.09.2020CET; Mbed Studio 1.2.1; mbed-os 6.2.1) it started to work. I’ve tested it on Nucleo-F207ZG and Nucleo-F746ZG boards.
