Try reducing the CPM load. If you have a serial  console  on  a  SMC,
shut it off, etc. Then try again (usually it will be better).
have to double check the writing procedure. But it is also worth to note that 
changing the PM (prescaler module) and lowering the SPI clock even more the 
writing problem is happening less frequently. 
Yeah. At a SPI clock of 0 no errors will happen. The problem is, that
this is not too much useful either ;-)
