Hi Hector,

Unfortunately this is causing unaligned access in my i.MX6. I'm specifically passing the -mno-unaligned-access when building this file so I guess it has to do with the macro and the packed structure.
I don't think this is due to packed structures, because -mno-unaligned-access tells the compiler that unaligned fields in packed structures should be accesses by breaking the unaligned access into smaller aligned ones, so this would not cause an alignment abort.
What can cause an alignment abort despite -mno-unaligned-access is dereferencing a badly aligned pointer, and this is probably what happens here.
Amicalement,
