possible fix, untested.
Hello,
this macros just look wrong, however I have not tested it.
HAL_DCACHE_FLUSH(), HAL_DCACHE_INVALIDATE()
and HAL_DCACHE_STORE(), and a fiew others:
The loop may fail to store the complete range, if
the start is not cache-aligned, for instance:
HAL_DCACHE_FLUSH(0x40000008,16)
flushes only one cache line instead of two.
