S32 Debug probe issue

[PraveenKumar_K]

Hi Team,

I am using NXP S32R45 EVK and S32 Debug probe. By starting with an New S32DS Application project, I am using S32R45 Family(S32R45 Cortex-A53 Linux) and NXP GCC 9.2 for Arm 64-bit Linux Toolchain and created a project and build successfully.

To debug the code, by creating a New Debug Configuration selected with S32 Debugger and by selecting the Hardware core and checking the debug probe connection. I am able to connect to the EVK board by checking the "Test Connection" button, then to start Debug I clicked the "Debug button" but ended with the below error . 

"Failure during execution of python script" and "Connection closed by the GDB server." 

can anyone suggest me how to solve this issue.

Hello Praveen,

Your project was created for Linux target, but it seems you are trying to debug with baremetal/bareboard configuration. Please make sure the target is not booted with Linux BSP running at the time the debug session with S32 Debugger and S32 Debug Probe is used. For example, if Linux BSP is loaded to SD card and board is set for boot from RCON, with RCON set to SD card, then either remove the SD card from the slot or reconfigure the board to boot from serial instead.

The S32 Debugger does not support Linux-aware debugging at this time.

Best Regards,

Mike

Hi Mike,

I had created my project with Linux Target only. Initially I tried without removing from SD card from EVK, later I removed the SD card from the EVK and tried to debug it with different Boot configuration settings. Even though I am facing the same error. 

Is there any other way to debug that issue? 

I tried with "How to debug using Command line GDB Debugging with S32R45" by referred this link from NXP community --> "https://community.nxp.com/t5/S32-Design-Studio-Knowledge-Base/HOWTO-Command-Line-GDB-Debugging-with-..."

In this, I was able to reach till step 4.. while trying with step 5, I am getting error like this.

Kindly suggest me know how to proceed further.

Thanks.

Hi Praveen,

The best way to debug this application, since it is built for Linux, is by using the C/C++ Remote Application debug configuration:

I suggest you follow the steps detailed in the following article. While it is for another device, the steps are nearly the same.

HOWTO: Setup A Remote Linux Connection in S32DS fo... - NXP Community

Be sure to download the SW32R45_RSDK_Linux_SDCARD_0.9.5_D2204 from this site:

https://nxp.flexnetoperations.com/control/frse/product?child_plneID=820747

First login to your account on NXP.com, select Software Licensing and Support, then proceed until you reach the Product List page, then use the link above.

Use the image from this download and program it to an SD card and install to the EVB. Setup to boot from SD card. Just like described in the HOWTO linked above. Sorry, we don't have a HOWTO like this for S32R45.

Please try it and let me know,

Mike

Hi Mike, Thanks for your quick reply.

I followed the steps with Remote Linux connection for S32R45. i was able to ping the IP address of my Target from Putty Terminal but while starting debugging with the Target gives error again.

[mikedoidge]

Hi Praveen,

From the error message, it seems it is not able to establish a connection to the target board. Probably the IP address is not correct. I know for my home network, each time I reboot the Linux on the EVB, the IP address is incremented by 1. So instead of 192.168.3.116, it would be 192.168.3.117. Please check the IP address again by using the 'ifconfig' command when connected using PuTTY over the USB connection. One additional thing, you can also setup PuTTY to connect to the board over ethernet, this way you can confirm the ethernet settings are correct.

Best Regards,

Mike

[PraveenKumar_K]

Hi Mike,

sorry for the delay from my side. yes as you said, each time I reboot the Linux on the EVB the IP address is incrementing. I am checking the IP address everytime &  changing in the setting in Debug settings. I also setup PuTTY to connect to the board over ethernet, still i am not able debug the issue.

let me know if i can check any other way to debug.

Thanks.

[mikedoidge]

Hello,

If you were successful in connecting to the board via ethernet with PuTTY, could you share the screen capture of the result?

If this is working, then there should not be an error from S32DS regarding connection issue with the board. They are using same communication setup. I see you have changed from Windows host to Linux host for S32 Design Studio installation. Could we focus on getting one working before we introduce potential new sources for issues? Perhaps switch back to Windows, as this is what I am more familiar with and can help you best on?

Best Regards,

Mike

Hello Praveen,

After the error is received, without terminating or deleting the debug thread, go to Window -> Preferences menu, enter GDB in the search field. Next, click on the GDB in the results panel and look for 'Show the GDB traces console with character limit:' check box and check it. Click 'Apply and Close'.

Now, go to console panel and select the 'GDB traces' console:

Send us the log displayed in this view.

Mike

I am able to complete the steps until step #5.a after which I am facing the issue for board_init(), I think you were facing a similar kind of issue at some point, so can you please guide me through over it @PraveenKumar_K ? thankyou.

Hello @prabhat_ and @PraveenKumar_K,

I finally had a chance to get back to this thread. I noticed there was an error message 'Import Error: no module named enum'. This means that the enum package is missing from the Linux Host OS where S32 Design Studio is installed.

Please see the below section from the install guide:

Best Regards,

Mike

[prabhat_]

yes already did that one, forgot to update. It is working fine now.
