Hi, everyone.
I have a LPC Expresso 1769 Board. And I planning to buy some LPC810.
And I tried to find some info about using LPC-Link of 1769 Board with LPC810.
Its possible without cutting the board? And where can I find how to connect the boards?

Thanks
Daniel

But the other 3 pins doesnt need resistor? Im just asking because of the 3rd image content

GND doesn't need a pull-up :bigsmile:

Pulling-up / down for SWDIO and SWCLK isn't required...

Thanks a lot =) Now my mind is clear

So the "only" think I need to worry about is to correspond the pins of this images.

SWD is working with a simple 4-wire connection:

SWDIO, SWCLK, Reset and GND. Some parts don't use Reset, but I'm not sure if LPC8xx is using it.

Connect them from J4 to your target chip and disconnect (cut) them from the LPCXpresso target board (LPC1769).
Otherwise LPC-link is seeing 2 targets :((

Then add a pull-up (10k) to Reset and connect 3.3V to your target :)

That's all :O

My bad, sorry, I read all again. I has a bit confusing about pinning

So the "only" think I need to worry about is to correspond the pins of this images. And apply some resistors. On LpcExpresso IDE do I need change something?
I think I will buy the 810 tomorrow.

And where should I conect JTAG RTCK?

But I need LPC800 Mini-Kit?

For what? As target?

Yes, it's important to cut the SWD connection, not the board...
