Title: Software reset of LPC2478
Post by: jezc on December 02, 2009, 10:08:41 PM

Hi,

I'm looking for a way to perform as complete a reset of the LPC2478 through software as I can.

Our hardware currently doesn't include any way for the processor GPIO pins to force an actual hardware reset so I'm hoping there's a way to achieve basically the same result using just software.

On other processors (e.g. Coldfire), there's a reset register which includes the ability to perform a software reset of the whole device - but I can't see anything similar for this processor.

Can anyone offer any suggestions please?

Thanks in advance

Jez

Hi Jez

Have you tried the reset command fnResetBoard()?
This will enable the watchdog and feed it a back feed sequence so that it immediately resets the board.
