Lpc2000

Hi,

Have you tried talking to the device over a serial terminal program 
like "HyperTerminal" or "TeraTerm"  instead of using the ISP utility. 
You can start by issuing a "?" and then the part would return 
with "Synchronized"...then would follow the ISP procedure. I think 
this flow is mentioned in the UM.

By doing this you can get a more detailed picture of why ISP is 
failing. If a ISP command fails/succeeds the bootloader always 
returns a "code".

Using the code, you can get more information from the part regarding 
this problem.
