Thanks Fabien,

Now, as a side question, could you tell me which reference LEON3 platform is implemented by Qemu in leon3_generic?

It doesn't seem to match the one emulated by tsim.

Thanks.

With the LEON3 IRQ controller IRQs can be acknoledged 2 ways:

Thanks Jean-Christophe,

I tested the patch with our software and it works.
