"Connect" debug session type doesn't work

oznurcaliskan — Fri, 28 Apr 2023 11:10:55 GMT

Hi,

I am using CodeWarrior for MCU Version: 10.6 on my computer. I am trying to connect to the target without downloading. So, I tried to connect it with the "Connect" debug session type but it gives me an error "No source available for '0x00100068 (0x00100068)()'" and I cannot see the Variable's content or any of them.

P.S.: The address it gives in an error is my Reset Vector Value for Bootloader. If it gives you any hint.

I tried connecting it with the "Custom" debug session by unchecking the boxes "Execute reset sequence" and "Execute initialization script", but it also downloaded it which I don't want.

If anybody knows the settings need to be done, I appreciate it.

Thank you,

Öznur Çalışkan

Hi again,

Sure. Firstly, I am using the "Connect" debug session with the settings below;

The steps I am following are; I am uploading my bootloader code to a board and I want to be able to connect to the board to view the variables' change without downloading another code with the Connect debug session type I am getting the error below; (but, code doesn't crush down, it just stops and when I try to rerun it gives the same error with another hex values every time.)

So, I thought it maybe cannot reset itself? But, I couldn't find any debug configuration settings that need to be done for connecting to target.

Thank you,

Kind regards.

Hello, sorry about this but could you confirm, what is your target? Are you using an EVK? if not, is right you are using a Universal Multilink as an external debugger?

Best regards,
Pavel

Hello Pavel,

The platform I am using is, we can say it's like EVK but not the same. It is a prototype Engine Control Unit (ECU). In this prototype, I have an MPC5642A microcontroller (that's my target) on an XPC56XX EVB. And, yes you're right I am using USB Multilink Debug Probe as an external debugger. ECU is connected to Host PC via JTAG Port using USB Multilink Debug Probe.

Thank you,

Kind Regards.

Hi @oznurcaliskan

this is not an "error":

This says that you are connected but you do not have debug information from elf file. If you click on View Diassembly, you can step asm code. But you won't see original source code, symbols etc. Only pure asm instructions.

You wrote that it is address of your bootloader. But there's application project selected:

If you want to see debug information for bootloder, you need to select bootloader project here.

Lukas

Hi,

Actually I tried the same process with Bootloader code, but it gave the same warning:

Can you provide me a procedure for connecting to target without downloading? I only want to observe variables' behavior.

Thank you,

Kind regards.

Well, it's interesting that this doesn't work. Something similar works in S32 Design Studio.

Anyway, I found quick workaround - go to Debugger tab and add elf file like this:

Then you should see the source code. It is possible to add more elf files here, so you can add elf files for both bootloader and application. I didn't test more elf files but I expect this should work.

Hope this helps.

Lukas

Hi again,

It worked it just needed both .elf files to be added as you showed in your reply. Thank you so much

Kind regards,
