RE: [qemu-hexagon] Error mapping file: Invalid argument

[Waksmanski, Lukasz]

Thanks for pointing me to the toolchain. I'll give it a try to see how it 
works. 
However, I'm more interested in being able to use qemu-hexagon as shown in my 
example below (QuRT).
Is it possible? What kind of modifications qemu would require to make it happen?

Cheers, 
Lukasz.

Yes, that's roughly it.

In order to build Linux userspace binaries, you can use the toolchain in the 
QEMU container or this one
