- Subject: syscalls and libsysbase support in newlib?
Hi!
I'm using the newlib on a small, bare-metal Cortex-M3 device (using the
CodeSourcery toolchain).
Right now, I'm facing the same problems, I bet every other bare-metal
developer has to face too -- implementing proper i/o syscalls for the
UART, file system, etc..
Especially I need a way to define light-weight device drivers, and a
simple VFS of sorts.
After some searching, I found wintermute's (Dave Murphy's) libsysbase patch:
http://sourceware.org/ml/newlib/2006/msg00451.html
It seems to be used a lot in Game console programming, and the patch is
already integrated into the devkitpro Toolchain..
Apart from the single post in 2006.. are there any plans to integrate it
into the official newlib release? It would benfit any derived toolchain
a lot, and would provide a good, standard way to access devices on
bare-metal systems.
best regards,
