RTC problem

2005-11-27 by r_bottleneck

Hello,

I  have a stupid problem with the LPC2138 RTC.

The RTC works with my SW on an Olimex EVB perfectly . However, I
designed an own board and the same SW doesn't start the RTC .

I checked the new board several times it seems to be ok. Also I
checked several different  crystals, as well as different capacitors
without success.VBat is supplied correctly. Even if the RTC clock is
supplied by the internal clock, the RTC does not work.

Is there something I forgot to take care ?

Thanks for any help.
