LPC-link2 will work with anything. It really doesn't matter what the target is.

What is your problem?

Please read the User Guide provided with your product. There is a mini tutorial provided in there.

This looks like your LPCXpresso is doing a probe discovery (i.e. looking at your system to see what debug probes are connected), and hanging.

What OS are you running on your PC?

And what boards / probes have you got connected to your PC?

From the release notes displayed during install (and accessible in your install - ReadmeLPCXpresso.txt):

Quote:
* On Windows 8 and 8.1, if both an LPC-Link1 and a debug probe that
   uses the 'Redlink' driver are connected (such as LPC-Link2 or a
   CMSIS-DAP probe such as LPC800-MAX), then booting of either probe
   will fail and appear to hang. To workaround this issue, connect
   only one debug probe.

One way to fix this for your system where you are only using LPC-Link2 would be to configure LPCXpresso to only look for certain probes.

Window - Preferences - LPCXpresso - Debug Emulator Selection

and untick the two LPC-Link entries (and Red Probe Family). This should then cause LPCXpresso to only search for Redlink and CMSIS-DAP probes.

LPCXpresso Support

Hello again
Actually I had some problems in OS ,now I 'm trying in another PC that I suppose it is better ,I run Win7.

I use link link2 now , but it can not recognize core ,
in lpc link 2 in jp7 we have :
[img=400x400]http://s6.uplod.ir/i/00603/ortjxvfn72ox.jpg[/img]

Should I connect TMS , TCK,TDI , TDO to the same pins in core whit out any pull up or pull down ?
And also JTAG RESET to TRST ?

I have n't make any wire for pines 7 and 1 in jp7 , so I am not sure that it is correct.

and what about RESET pin of core ?

I saw that I have to pull it down during JTAG debug .

Hi , Thanks a lot.

I saw that and I put pull up and pull down resistance that there were not in my board .
but it is not working yet .
I try to change from JTAG to SWD and wired it as the data sheet because I want to know is it only the problem in JTAG or not !

in lpc expersso 7.6.2 that I use , I can not find any place that can change debugger to SWD or JTAG .

I think , my major problem is in lpcexpersso , maybe I have not chosen correct debugger yet .

As you can see , there is not any DEBUG Protocol part !!

I'm not sure as to what exactly you are doing, but the way to start a debug session is to use the QuickStart panel's Debug option. This should then automatically identify the debug probe connected to your PC and configure the debug session appropriately for your target.

I strongly suggest that you go back and read the LPCXpresso User Guide (available within the product installl) that you have been pointed to previously. as well as watching the Rapid Embedded Development with LPCXpresso video available from http://www.lpcware.com/lpcxpresso.

[As an aside - LPC11E68 only supports debug connections via SWD, not JTAG.]

I did it but it can not recognize the core!!

OK , now I want to debug by SWD, only it , but I have already a problem in core connection with lpc link2 ,
I can program by flash magic , and I am sure my core is ok and working .
but LED1 ( BOOTO-LED) in LPC LINK2 is blinking , I think it isn't normal .

another thing that I want to ask is , In SWD ,as you send me a link http://www.lpcware.com/content/faq/lpcxpresso/debug-design] ,
in Cortex 10-pin 0.05" JTAG/SWD Connector Pinout , I wired SWDIO , SWDCLK to my borad , but nRESET should be connected to RESET of my board also or not ?

It seems that my problem is as similar as http://www.lpcware.com/content/forum/lpc-link-2-problem]

Cortex-m0 is swd only. It does not have jtag. The problem is almost certainly in your debug circuit. Fix it and you will be able to debug!

Hi, every body ,

I put jp2 ( in Lpc_Link2 ) in close position , and now it passed that situation ,

Actually my board has own power supply so in fact it dose n't mater to close jp2 , Beside I haven't connected any wire except Swd_clk , Swdio and GND and reset .

by the way , it is working and program flash in SWD but I can not debug yet ,
Now step over and step into and etc in inactive !!

and I can only program no debug !!

Nope:

http://www.lpcware.com/content/faq/lpcxpresso/debug-design:

Quote:
On the LPC-Link2, when JP2 is shunted this will power the target side of the dual-supply buffer and provide power to the target through a diode on VTref. [color=#f00]With JP2 open the target must supply the VTref to power the target side of the dual-supply buffer.[/color]

Thanks a lot ,
the other problem maybe is for reset pin ?

[img=400x400]http://s6.uplod.ir/i/00603/ortjxvfn72ox.jpg[/img]

Lpc_LINK2 ,as you can see, has a Reset pin , I'm not sure what I have to do , as you see this is Jtag Reset and I am using SWD , Beside this is reset and my core - Lpc11e68 - has nreset, so it is not of reset .

There's no official list if Reset is used or not...

See: http://www.lpcware.com/content/forum/lpc15xx-minimal-swd

Therefore I would suggest to connect Reset (which is of course NReset = low active).

If a simple 4-wire SWD connection and closed JP2 is not working, it's time to check your board hardware...

Thanks for the kindly reply,
Now , It;s almost running but actually I can not debug !!

I want to debug my firmware line by line and also see anything ,

I can not even see step over and like that in the top menu because those are disable !

I can speak and show its states at present for you if you have Viber or Telegarm or something like that on your phone!

I don't know why but it is not all thing that I want for debug.

I have experience to work by IAR and Jlink for JTAG , that I can see and debug firmware and debug by lpc1168 .
