    We are having some issues with using newlib-nano when using swprintf and floating points. We have tried using newlib-nano with floating-point support. But our code will only perform correctly when using the “default” libc.

    • What version of newlib-nano is available in VisualGDB?
    • Does it support wchar_t at all?
    • What is default libc?

    Hi,

    Our ARM toolchain is based on the same sources as the official GNUARM toolchain (specifically, the 9-2020-q2-update release). The only difference from the original toolchain is that we rebuilt it with big endian support.

    Please refer to the official GNUARM documentation for specifics on supported libraries, versions and features.

    P.S. We are also working on an updated toolchain build based on 10.3-2021.07, however, it is also directly based on the GNUARM toolchain sources and will work exactly the same as it.
