Yes, both paramaters need to be the same, so your fix is correct.

Hi,

It seems to be a mistake in "compiler_abstraction.h" line 140:

  #if (__VER__ >= 8000000)
        #ifndef __ALIGN
            #define __ALIGN(n) __attribute__((aligned(x)))
        #endif

Shouldn't the parameter be 'n' or 'x' in both cases?

I changed it and compiled without errors.

After some more research about that topic I found the solution of the problem. It is a problem with IAR 8.xx.x, which is also mentioned in:

The solution is to replace the file modules/nrfx/mdk/compiler_abstraction.h with the file from download

of Verison 8.42.0 GCC 3-clause BSD license

After doing this, everything is running correctly.
