Hi,
Thanks for the reply.
So as you said,
1)I've augmented the jetson-tk1-demo.c config with an ivshmem device and a
shared mem region, using to configs/jetson-tk1-linux-demo.c as reference.
2)I replicated the ivshmem-demo from x86 to inmates/demos/arm and hooked it up
in the Makefile
I tried to cross compile the same and I have encountered a few errors.
>From what I've observed, the errors are mainly regarding the pci related
>functions.
How can I proceed with this?
PFA the error log.
Thanks and regards,
Harikrishnan
