No need to wait between the writes.
Due to all the rubbish text above I forget the question... ;-)
This fix is quite simple to implement. in lowlevel_init.S edit the values for MCKR (as shown below). You also need to modify the length of the assembly loop some lines above which iterates through this list (also shown below). This length should really be calculated (but it works).
Thanks a million.
Then define MCKR_VAL0 as the first value to be written and MCKR_VAL1 as the second in the includes/common/csb637.h file.
Hope this helps,
Sure. Maybe you could send unified diffs next time as they're much easier to read.
Thanks anyway!

Aah. I forgot that. Cause I thought the original autjort would never do a bad thing like hardcoding such a loop count ... ;-)
