Tock Userland LibC

Newlib is a port of the C standard library designed for embedded systems. Tock uses a version of Newlib compiled to support the position independent code that Tock applications require.

Compiling a new version of Newlib

In the Makefile, edit the variable NEWLIB_VERSION with the version you want to compile. The releases are listed here.

Then:

$ make

When the build finishes (it takes a while) the copy of libc.a and libm.a that we use can be found in the thumbv6m folder.
