Hi,
Anybody having some LPC2xxx reset problems and got that solved before?

I'm having some LPC2124 reset problems:
- Date code 0403AY (Quite new chips, not the very old reset problems)
- Will not get reset properly, may be ~ 3-4 out of 100 times failed.
- If it is running, it is very stable.
- I'm on 2-layer PCB eith good de-coupling capacitors for both
1.8V and 3.3V. 18.432Mhz external OSC.
- Tried with adding MCP100-2.7DI as reset chip but still do not
get problem fixed.

If you have similar problem and solved it before, pls provide
me with some pointers/hints.

Thanks and Best Regards /MH
