Hi every body
I am designed a board by lpc11e68 and I am going to use LpcLink2 as debuging by Lpcexperso .
as I found lpc11e68 ( cortex m0) dosn't work by jtag debuging , so I used to use SWD , swd has 3 pins SWDIO, SWDCLK AND SW0 , I make connection for SWDIO and CLK but I am not sur of SWD0 . what about vcc.

flshing led1 in LpcLink2 what it mean .

Please read the FAQ:
http://www.lpcware.com/content/faq/lpcxpresso/debug-design

The flashing LED means that the LPC-Link firmware is running and responding. It does NOT mean that there is a valid target connected.

Thank you ,
I saw that link and also lpc11e68 datasheet but I can not find JTAG Test Data Output / SWV trace data output (SWO) in lpc11e68 and I am not sure of it yet.

Cortex-M0 (LPC11E6x) does not support SWO (Trace) capabilities, nor JTAG.

by the way Is it posible for to debug by SWD and see everything and make breakpoint where I want like Cortex-M3?

Of course. SWD provides the same capabilities on all Cortex-Mx based MCUs.

So what 's the defference between Debug with Trace and whitout.
I used Cortex-m3 ( specialy LPC1768) for Debug by JTAG , and now I want to use Cortex-m0 (Lpc11e68) for debug by SWD.
I make wiring for SWD but I am warried is it give me that benefit for debug line to line and see code like JTAG .

I checked my wiring several time but when I want to debug by SWD "no connect to core " message shows.

another message that is a bit stange for me is:

I know that it has not JTAG but it shows that it is JTAG and I can not find any place to change it.

1. When postin long strings of text please do it between code tags (the # symbol on the toolbar)
2. SWO Trace is something that has no effect on debugging. When present, it uses an extra pin on the connector
3. "Has JTAG" means that the Debug Probe (LPC-Link2) is capable of supporting JTAG - it is nothing to do with the target
4. "Could not connect to core" could mean several things
- you have not correctly wired up your debug connection
- the target is not powered
- the target is stuck in reset
- the target needs booting into ISP mode

Sorry for log text , In feuture I will do it by # .

I mean the " WireProtocol = JTAG" not "HAS JTAG" this tell me that JATG is using or I am wrong ?

Would you please tell me more about it ?my core is working and I send a file by FLASH MAGIC to it and it is ok , Now I want to in later working use DEBUG to find my mistakes and make a best application for it .
thanks for your reply

Please read this FAQ:
http://www.lpcware.com/content/faq/lpcxpresso/regaining-debug-access

Have you configured your project for LPC11U68?
http://www.lpcware.com/content/faq/lpcxpresso/changing-project-mcu-target

After doing that, make sure you delete your launch configuration before start another debug session:

Thanks alot , I saw and did all of that particulay Boot into ISP mode and Vector catch=true , but yet It Could not connect to core.

So, you have a hardware problem then. Suggest you fix that.

I have checked hardware several times.
Besides I am sure that my chip ( lpc11e68) is OK because I check it by Flash Magic , I have seen something about IOCON in page 59 in user manual !
Is it necessary to define SWD pin to SWD function ? I mean that maybe I have to enable SWD .

I tried to change and use IOCON but I can .
first of all
LPC_SYSCON->SYSAHBCLKCTRL |= (1<<16);//IOCON
is OK , but LPC_IOCON-> has error .

How I can use it?

Re-read the FAQ and if you still have problems then post details/schematics of your board design - in particular debug and reset.
