MCU-Link Debug Probe

willychou — Thu, 21 Sep 2023 02:11:10 GMT

Hello.

I have some questions.

I have bought MCU-Link Debug Probe and try to replace our old programming board(LPC812-LPCXpresso).I always use LPCXpresso to execute my program ,but when i connected Debug Brobe,the program unable to read it.

Is MCU-Link Debug Probe support LPCXpresso? Or only support MCUXpresso?

If it can,how to connect it on LPCXpresso.

Thanks for the answers.

Hi,

Sorry, I am not clear about your question.

I see you have the MCU-Link Debug Probe, as you know you can use the MCU-Link Debug Probe to download/debug the LPC family with Cortex-Mx core, can you tell us the target MCU part number and the tools you rare using?

Hello.
My MCU number is LPC1114FBD48,and i use LPCXpresso to running my program.
After i connect Debug Probe,i press program flash in LPCXpresso,the program usually can't find the emulator,or it can't use the function.
The red light on debug probe is shining.

Hi,

As you know that the LPCXpresso tools has not upgraded for a long time, now, the MCUXPresso tools is used, I suppose that LPCXpresso tools does not support the MCU-Link Debug Probe.

OK,thank you for your help.
But i have the other questions.

when i used MCUXpresso to run the program,it appears this error message,but i already check the schemetic.

i use 4 pins,J6: 3V3,GND,SWDIO,SWCLK.

if i want to use this Debug Probe,which pins are nessesary to connect or i need to do some steps?

what's the main function for the Debug Probe.
Can it burn program in to t-con board?

Hi,

From the website, you can see that the MCU-Link supports the LPC11xx family.

Hi,

I suppose that the LinkServer is a debugger, it can erase/program flash.

Pls refer to the section 10.5.2 Flash Programming in the MCUXpresso_IDE_User_guide.pdf in the directory:

C:\nxp\MCUXpressoIDE_11.7.0_9174_prc

Hope it can help you

hello,now i'm using MCUXpresso_IDE v11.8.0_1165. to connect with the board via MCU-Link.
I couldn't able to flash to board. I can see below the error every time.

Hi,

Pls try to click "debug" to download the application code to flash with MCUXPresso tools

Hello,XiangJun Rong

Thanks for your help,I have solved this problem,it's working now.

I noticed when the probe connected the extension board,Voltage droped to 0.8v,not enough to make program move.

So i connect the other power to supply Voltage,and the problem has been solved.

thank you so much.

Hi Willy,

I wanted to provide some simpler answers to questions you asked earlier in this thread.

LPCXpresso doesnt support MCU-Link; as you correctly observed, we haven't been adding features to this IDE for a long time, and MCUXpresso IDE has many more features and improvements (plus its 100% free).

LinkServer is a utility we introduced this year (2023). Amongst other things, it enables you to program the flash of a target from the command line. Although you can do this with the MCUXpresso IDE installation, that can get a little complicated due to the need to get the paths to the flash driver correct (and these change per release/version).

On the voltage drop issue - please note that the base model MCU-Link cannot power your target. The MCU-Link Pro can.
