https://devzone.nordicsemi.com/f/nordic-q-a/47866/would-it-be-possible-to-output-bsd-trace-to-sdhc-file-systemI&#39;m looking through the NRFX library and specifically the CONFIG_BSD_LIBRARY_TRACE_ENABLED feature and would like to know if it would be possible to redirect the trace output to a file on an SDHC card.
