I forgot to give you a proper answer on this one: I think it 
should work, as it's a STM32F401 microcontroller.

-So basically you get a 'bare metal' setup with no drivers.
However, as you know already, you can use STM's drivers, because 
D works quite well with C, so you have a fairly good starting 
point.

I hope to add more devices later on, and I also hope to add a few 
convenience libraries and perhaps some runtime for bare-metal.

I do have some additional files, which I didn't want to put in 
the STM32F4xx repository, since they're not directly D-related. 
They include a few linker-scripts and a Makefile (but the 
Makefile will probably not be to your liking, as it assumes a lot 
of things and is not Windows-compatible).

The current linker-scripts can be downloaded here:
d.gpio.dk/dl/linker-scripts.zip

You may want to cripple the following slightly:

	__exidx_start = .;
	.ARM.exidx :
	{
		*(.ARM.exidx* .gnu.linkonce.armexidx.*)
	} >flash
	__exidx_end = .;


by changing it to:

	__exidx_start = .;
/*	.ARM.exidx :	*/
	/DISCARD/ :
	{
		*(.ARM.exidx* .gnu.linkonce.armexidx.*)
	} >flash
	__exidx_end = .;

Both Mike and Timo are the true pioneers here; they have done 
very valuable hard work. Johannes made it possible to use the 
weak, alias and section attributes, so we have the most important 
functionality for microcontroller support.
