    Hi all,
    I am facing somewhat strange problem in LPC2141 based board.
    I used H-JTAG emulator to dump the project. Code written is supposed to toggle a pin for making a led glow on and off. I have checked the code with proteus and it works fine.

    Now, the problem is the board some times shows up the result and sometimes not. We have checked the power supply and grounding sections, they are OK.
    But the output is getting showed up. I dont understand where on earth it went wrong.
    Please help me out.
