I have an LPC1776 PCB I have made.
It works except for one very strange problem.
It constantly pumps out 8 text INTs via the ISP header (UART0), even when reset button is held down!
My software works fine, but I cannot stop this data from coming out.
It even happens when there is no software inside the LPC1776!

eg:-
1BEF 125C 0DA6 0B3F 2A09 2A15 2A26 2A29
1991 1719 0DA7 1267 2A0B 2A17 2A28 2A2C
1BF1 22F2 1005 1004 2A0B 2A17 2A27 2A2B
1BF0 125C 08E6 0B3F 2A0A 2A15 2A27 2A2A
1E50 1E33 08E6 1004 2A08 2A14 2A25 2A29

Non stop forever!

Solved
A short on the PCB meant a 2nd CPU was sending data on those lines
