Freedom Embedded

CodeSourcery provides toolchains for many architectures, and among them there are “bare metal” toolchains that produce programs that can be run natively on the processor.

In the past I already explored some possibilities about developing bare metal ARM programs:

In my opinion the most interesting purpose of the bare metal toolchains is development on small microcontrollers, such as the ones based on Cortex-M processors.

My beloved QEMU is able to make me try a system without buying the hardware first; in particular, mainline QEMU can emulate the Texas Instruments Stellaris lm3s6965 microcontroller, which is a Cortex-M3 based chip that has 256KiB of Flash, 64KiB of RAM, some serial ports, ADConverters, timers and many other peripherals.

I wanted to be able…
