A13 never boot with GPS on UEXT

[edolo]

Hi!!
Like the subject, with GPS connected on the UEXT, the A13 try to boot, but after five seconds prompt of the shell is ready and the X doesn't start.
The last message of the boot say "hit any key to stop the boot".
If i reboot with the GPS not connected, the A13 start properly. In this way i can recconect GPS and it run properly too.

Of course i'm looking to start the A13 without sconnect GPS.

Any suggestion?
it's possible then the NMEA sentences are like a key pressed?

Thanks a lot.

Edo

P.S: Sorry for my terrible english
