Does Linux on TX1 not support MS_SYNC option for msync?
I mmaped hardware buffer to memory and modified the contents of the memory.
I had to use sleep for about two seconds before the change is written back.
To avoid using sleep, I thought using msync with MS_SYNC is the desired effect I was looking for
But when I try to do so, msync returns EINVAL.
I’d appreciate any comments or advices.
