when you'll have some time, perhaps it would be useful to install GNU ARM 
Eclipse and generate a project for your board, run it on the physical hardware, 
then test it on QEMU.

did you implement the clock related registers? PLL & others? these are used 
during CMSIS SystemInit() and are mandatory, otherwise emulation will either 
fail or not be realistic.

thank you!

yes, that's great, but without a proper base, like system registers and debug, 
usability may be not be as good as expected.
