    Hi, not a big problem, but I’m doing some stm32 development and printf appears to not support 64 bit.  Tried %llu and PRIu64 but it just outputs ‘lu’ instead of a number, and swallows the next two parameters.

    Hi,

    This looks like a limitation of newlib-nano. Please follow the link below for known workarounds: https://github.com/RIOT-OS/RIOT/issues/1891

    Ok, thanks.  Yes, it looks like a newlib-nano limitation indeed.
