Re: Olimex LPC2106mt bootloader problem

Nick,

Thanks for letting me know about your LPC 2106 problems. Since I'm 
working from home today I do not have any other cables but I'll get 
back to you as soon as I have tried a different one. As I wrote 
earlier, I have tested different baudrates and made sure that the 
comport was correctly setup. I'll check that with a scope tomorrow. 

Best regards 
/Anders
