comment How can I find the cause of clock drift on a custom embedded system?
@Nils The G25 does not have two 16 bit counters, only one. The other counter register seems to add some increment after 20 minutes or so. So the patch avoids reading the other counter. The G45 does have both counters.

@Nils - yes just finished initial testing, took about 20 minutes to demonstrate the original problem

Thanks for the insight. The clock=jiffies did work for me as a workaround. The actual answer is we missed an Atmel supplied patch for the 2.6 kernel that patched the tcb_clksrc.c for the SAM9X5 processors. Just too tired to see it last night, but now it's pretty obvious.

comment How small can an embedded Linux file system get?
Thanks - I do need to support kernel modules. Right now I am using the a given init - but I am very new at this. Do either of you have a favorite tutorial for building a file system? Leave as an answer and I will close this out
