MCUXPresso IDE can't debug through JLINK

Vinos — Mon, 13 Nov 2023 09:02:34 GMT

Hello everyone, I'm using MCUXPresso IDE to debug my program. Since the NOR Flash is connected to the Secondary group of FlexSPI1, I needed to modify the Flash download algorithm myself.

For DAP, I successfully modified the .cfx download algorithm file, and the program can be debugged through MCUXPresso IDE.

Recently, I started using JLINK for debugging, so I finished the corresponding Flash download algorithm file with the .FLM extension. I added a new device in the JLINK installation directory and used this download algorithm. After testing with J-Flash.exe, the algorithm successfully erases and writes the program.

Next, I used this new device in MCUXPresso IDE. After clicking "Debug," the program can be successfully downloaded to Flash (the program runs correctly from Flash after a reset without debugging). However, I cannot debug it within MCUXPresso IDE.it seems like the IDE doesn't recognize the program at address 0x30000000 and there's no disassembly code.

I've tried adding scripts in the configuration, but it hasn't been helpful.

Did I miss any steps, and what should I do to debug with JLINK in MCUXPresso IDE?

I would greatly appreciate your response.

Hi @Vinos ,

Which Flash download algorithm you are using now?

Do you try the RT-UFL or not?

I think you can try to modify the RT-UFL, and generate the flash algorithm, and use that jlinkscript.

I used the RT-UFL project to generate the Flash download algorithm. I tried the jlink script you mentioned, as well as some other scripts, but they didn't work. However, I was able to debug in Ozone, so I think it might be a problem with MCUXPresso IDE.

Hi @Vinos ,

Thanks for your updated information.

so, the JLINKDevices.xml is also modified, right?

In fact, to the default algorithm to debug the MIMRT1170-EVK with RT-UFL, that debug is working.

Which mcuxpresso IDE version you are using? V11.8.0?

Best Regards,

Kerry

I added the information in JLINKDevices.xml like the image you provided, and also specified the link script. But it's no use. The IDE version I used is 11.8.

This is the situation where my Flash is connected to the Secondary Group of FlexSPI1. In another board, my Flash is connected to the Primary Group of FlexSPI2. Same issue.

Hi @Vinos ，

Thanks for your information.

So, now your situation is:

FlexSPI1 secondary pin group connect QSPI flash

1. boots OK

2. CMSIS DAP debug OK

3. JLINK debug failed with mcuxpresso, right?

Please check the private message to you, then give me the private message, thanks. As I lack the related platform to test it.

Hi @kerryzhou ,

Can you please provide the solution?
As I am also facing this issue

I am also using HyperFlash for my custom with IMRT1176
I have the JLinkDevices.xml as mentioned above

Hi @razools ，

If you have any issues, you can create your own question post, then we will help you in your own question post, thanks.

You can refer to:

uncheck the item “Reset before running” in the debug configuration.

Wish it helps you!

Thanks @kerryzhou
Your suggestions worked

However, I am facing a different issue now. Will post it on my question post
