As we have almost 80 irq lines and 40-45 NVIC_irq's.
Where can I define them?

Hi,
I was going through the aspeed ast2600(not evb) it has Dual-core Arm A7 and

Hi,
I have a hardware which I want to emulate on QEMU based on arm Cortex M3. I
tried to follow the examples like mps2 or stellaris.
I'm finding it really hard to figure out how can I test the

contains all major protocols like
