Hi,
I've been using an EPM900 board with an LPC936FA chip for the last few weeks, and when I tried switching to debugger in the EPM Emulator mode a few days ago, I got the message that the Bootloader was not running.
I checked up the forums, read through the following threads and concluded that the board must have been damaged: - http://www.keil.com/forum/docs/thread6754.asp - http://www.keil.com/forum/docs/thread4049.asp
Both these threads relate to the exact same situation, so maybe there is a common cause for it? Specifically, is it possible for some pin config or software code to cause this, because I don't want to repeat such a mistake.
Hope someone can help. Thanks, Avinash
maybe you are using external clock. Take a look here and try to configure it differently:
