[Henrik Torstensson]

Hello 

Yes, I am using timeouts in in my Events. 

How do I check if the clock has started? The return value from NutGetSeconds() seems to be correct. 

Thanks,

Henrik

Are you using timeouts? May be the 32 kHz clock doesn't
start at power-up.

You may also check for a difference with
- disconnect the DC supply
- switching on the DC supply

Some DC power supplies do have a very slow rising time.
If the reset controller is broken, this may produce
such kind of strange problems.

Yes, uninitialized SRAM may have different contents.
