printf causes hard_fault #nrf52840
I have an application for the nrf52840dk_nrf52840 board where I am using printf() to print some messages.
All works most of the time and the messages are shown correctly on my serial console.
However, at some point when I call again printf() my application crushes. Any ideas? Is it possible that some buffer is too small or something like that? Attached is a screenshot of the call stack.
