semihosting was the first thing I fixed in GNU ARM Eclipse QEMU, and since then I use it constantly.

I don't know if this addresses your problem, but perhaps you could also take a look there.

Hi, Liviu,

Thanks for the suggestion.

It seems like to me that the issue is the default address assumed by qemu, which is 0x0.
(since Eclipse QEMU uses the same code, I believe they have the same problem.)
But it's not always the case.
For example, zynqmp's ram base address is 0x80000000, 
and I have to tweak that address in HEAPINFO handling code every time I change to a new HW config.
