Harald,

Thank you for your reply, and thank you for NutOS.

What is confusing me is that _sbrk is indeed present within libnutcrt, and I can force libc before libnutcrt for the linker. And yet the linker claims not to see it.

Haven't tested the code yet to see if anything is broken by having sbrk.c in my project instead of (and, maybe, in addition to) the version in libnutcrt.

Thanks,

Bob Wirka

This typically happens, if you directly or indirectly call a library
function that requires an OS, but which is not available in the Nut/OS
lib. Candidates are stdio functions, but also memory allocation functions.
