Hi.

I wrote some bugged program to my LPCXpresso LPC1768.
It make MCU infinite exception interrupt, I think.

And I tried to re-write another program (FreeRTOS example project) to the flash.
But I couldn't it by the error messages.

Also debugging feature is same.
How do I fix the problem?

Regards,
Shin.

Review this FAQ:

http://support.code-red-tech.com/CodeRedWiki/DebugAccessChip?highlight=%28ISP%29

Your board seems to be in an unstable state. Possibly, you altered one or more PLL settings, or otherwise disabled debug access. This FAQ is an overview of a procedure to circumvent the boot process of your LPCXpresso board to prevent it from exiting the NXP bootrom after reset. This is a stable configuration which should allow you to reconnect debug. The ISP is further documented in the User's Manual. To boot into the ISP is somewhat more of a challenge with the LPCXpresso boards, since they don't offer push buttons. You'll need to ground the appropriate pins.
