Re: [lpc2000] Re: Uart receive timeout Interrupt?

2005-11-10 by Peter Homann

Hi,

Thanks guys. I'll break out the test gear tonight.

 From what is being said, it is either a hardware problem, or the LPC is 
not entering boot mode.

I can hold P0.14 lo, then use a terminal program to issue '?' and see if 
there is  a response.

Do you know what the rest of the command set is?, or will the '?' 
character cause the boot loader to spit it out at me?

Cheers,

Peter.
