Hello @witaradya 

How about try to debug a simple project like hello world that doesn't use this pin.

Thanks, the problem already solved. The problem is use PIO0_12 and reference this pin to GND. At the same time PIO0_12 use as ISP entry pin that a LOW level in this pin during reset starts the ISP command handler. The solution is set CRP mode to NO_ISP in startup_lpc804.c. change __CRP const unsigned int CRP_WORD = CRP_NO_CRP; to __CRP const unsigned int CRP_WORD = CRP_NO_ISP;. Thanks.
