I don't understand what "ISO stack" means here.
ISO == instead of.
That doesn't matter. If you are sufficiently unlucky it will land on a page boundary. You must not do DMA on the data section either.
Who said it was going to do DMA on the data section? The arrays got copied to heap-allocated buffer before DMA. But allocating those arrays on stack was not optimal anyway.
