Initial state of I/O Ports differ by booting from flash

Hi everybody!

I have following problem.:

When powering on the STR711 from flash (flash empty) the initial state of the I/O Pin 0.11 differs from the I/O state when powering on from ram.

That means if BOOT0=0 BOOT1=0 BOOTEN=1 (Flash), then P0.11 is low after powering on. And if BOOT0=0 BOOT1=1 BOOTEN=1 (RAM), then P0.11 is high after powering on.

(Before executing or loading any code into RAM/Flash; - just power on)

I want P0.11 high in both cases...

Any hints?

regards,

Erwin
