Lpc2000

Hi people! I'm new on this group... I need help with MCB2100 and 
ULINK communication. When I try to debug I receive the message 
Memory mismatch. This happens when I disconnect the J1 and J7 on the 
MCB2100 board. This means that I let the boot loader take control 
over the LPC (?????). But when I put them back, the uvision doesn't 
recognize the ULINK!!!! What's wrong

PS: I put the J9...
