Re: [lpc2000] bug in JTAG implementation?

2005-11-14 by Dominic Rath

I've seen similar behaviour on a LPC2294 I've used to test with. I asked 
philips support, and they told me they don't know about any problems...

Anyway, as you said, it doesn't affect debugging, and during Capture-IR, the 
correct value of b0001 is being loaded, so that's fine and can be used to 
validate the communication.

Regards,

Dominic
