Jlink&IIC #140

Closed DREAM669 closed 9 months ago

DREAM669 commented 9 months ago

Hello, I have encountered two issues. First question: How can I use JLink for debugging in VS code? What are the minimum pins that JLink needs to connect to? The second question: Reading sensor information through IIC and calling the IIC read interface resulted in an incorrect return value. What is the approximate reason?

Kampi commented 9 months ago

Hi @DREAM669 1) SWD needs

2) Hard to say. Can you please share your code?

I clicked the debug button, then it showed no connected device found.

Kampi commented 9 months ago

It looks like no SWD target is found. Also, your debugger looks strange because of the loading circle. Please do the following:

With a target it must look like this image image

Without a target image

It looks like no SWD target is found. Also, your debugger looks strange because of the loading circle. Please do the following:

  • What kind of debugger do you use? I am using J-Link as shown in the following image. 下载

  • Does the debugger get loaded correctly when no target is attached? Restart VS Code to be sure When I only connect J-Link to the computer without connecting it to the target board, it looks like this.

  • Can you expand the debugger menu and see a target? When I connect four pins（SWDCLK，SWDIO，GND，VTarget） to J-Link, it looks like this.

  • Does the power supply of the target work? Yes, the target board is powered properly as the screen displays normally.

Okay that looks good so far. Can you program the MCU? And please share your build configuration.

when I click Flash Button, it shows "No connected device found with serial number 1050050002. Either unlink the device from the build or connect that device." I Jlink serial number is 5930563, do I need change this number?

No, serial number is fixed, can't change.

Please use JFlash Lite and try do an erase in it. Also try flashing the built hex files directly using JFlashLite to see if it works. This will tell us if the debugger is working fine.

I previously used the nRF5340DK board for downloading programs to the ZSwatch, and it worked fine. The serial number (SN) of the nRF5340DK is 1050050002.

I am able to download programs successfully using the command-line tool, which indicates that my J-Link is functional. However, I am unable to download programs and debug within VS Code.

Ok, please try this: image

Try both of those, see if one of them works image

That looks correct, is there a question?

My problem is that I want to use Jlink to debug the program in VS code, but I get an error about "No connected device found with serial number 1050050002. Either unlink the device from the build or connect that device."

Did you try changing device provider as suggested?

DREAM669 commented 9 months ago

"No connected device found with serial number 1050050002. Either unlink the device from the build or connect that device." Does this sentence mean that the debugging tool I set before is nRF5340DK, and I need to set the debugging tool to Jlink?

DREAM669 commented 9 months ago

My nRF5340DK cannot work, so I can only use Jlink.

1050050002 is your DK? So the used device in VS Code is your DK and not the JLink. Can you please unplug the DK and plug in only the JLink to make sure that there is no issue? And please restart VS Code after removing the DK.

DREAM669 commented 9 months ago

Yes, 1050050002 is nRF4340DK. I have unpluged the DK. I guess what we have to do now is how to implement "unlink the device from the build"

OK! This problem is solved. Thank you so much！@jakkra @Kampi

Glad to hear that! Enjoy the hacking 😀
