External flash on P0/P1

We have a problem with accessing external flash ST M29F400BB) on the st10. We have checked all timings and voltages etc. When the system is powered on there is a multiple cycling reset (we use an external watchdog that ''fires'' every 20ms) for about 3 seconds. This period varies with ST10 temperature. The device eventually passes through this cycling and then runs as expected. This does not happen when the same software is run from the internal flash.

Has anybody had a similar problem?
