P2.10 as GPIO not working?

Hello,
I am using LPC1769. I configured pin P2.10 as GPIO, but when board is connected to the application, code is running strangely and debugging is not possible. When I disconnected pin P2.10 only, everything works fine. I tried repeat connection/disconnection of P2.10 and still with same result (connected=NOK, disconnected=OK). Do you know what can be the reason of such behavior? Pin P2.10 is physically connected to base of the bipolar NPN transistor.
Thank you.

Or is there a way how to use this pin as GPIO without restrictions?

Use a pull-up :)

Hello,
R2D2, thank you for good answer.
So it looks like I cannot use pin P2.10 as discrete output in my case. Or is there a way how to use this pin as GPIO without restrictions?

Yes, and it's time that you learn it, too.

P2.10 is the ISP pin, which you are successfully grounding with BE of your BJT :)

Then you are starting in ISP mode. See: http://www.support.code-red-tech.com/CodeRedWiki/DebugAccessChip?highlight=%28isp%29
