Hi Andrei,

Let say i want to boot MCU-target with J-link debugger. Below files must present on lava installation setup  or these files are only for reference/test purpose.

 
/usr/lib/python3/dist-packages/lava_dispatcher/tests/pipeline_refs/jlink-with-power.yaml     
/usr/lib/python3/dist-packages/lava_dispatcher/tests/pipeline_refs/jlink.yaml                
/usr/lib/python3/dist-packages/lava_dispatcher/tests/test_jlink.py  


YES , i found these files in repository , but not there after set-up LAVA from regular installation (sudo apt install lava).

Thanks
Veera

Hello Nagendra,

 

Files were moved since I created the pull request.

Please search them in the repository, I found jlink.yaml in /lava/tests/lava_dispatcher/pipeline_refs/jlink.yaml

 

You should use a docker container to install Trace32 as Milosz recommended, it should scale easy in the future.

Trace32 should reside on lava-dispacher (remote worker in your case I think), this is how I’ve done it in an older version.

The dispatcher it the component of Lava that actually interacts with the SW/HW you are testing.

 

Regards,

Andrei

Hi Andrei,

Good Evening.

Lava was installed in my machine with latest version 2020.04. And gone through your code.

But i failed to find the following files :

/usr/lib/python3/dist-packages/lava_dispatcher/tests/pipeline_refs/jlink-with-power.yaml     
/usr/lib/python3/dist-packages/lava_dispatcher/tests/pipeline_refs/jlink.yaml                
/usr/lib/python3/dist-packages/lava_dispatcher/tests/test_jlink.py
  

 

Is this Expected behavior???. or Am i missing something during installation

 

 

And i am using remote worker installed on one machine and lava-server is placed on other machine . 

Other tools like  trace32 where i have to deploy ? lava-server or remote worker..   

 

thanks

 

Regards

Nagendra S

With JLink you need to install Segger’s software on the server where Lava dispatcher resides (in case you have multiple Lava servers).

Hi Andrei,

 

Wonderful!!, 

Thanks for your time .. 

I need bit support from you, don't mine :) ,Can you please share your Jink scripts. I will use these as a reference will write comparable boot method for trace32 .

 

And if you can, Please share the appropriate Doc (link) to setup(interface) other software's in Lava server.  Setup Jlink with Lava server also fine. 

 

 

Regards

Hello Nagendra,

 

JLink was added as most NXP mcus use this interface, there is no support for T32 in Lava as far as I know.

Even if they use the same JTAG interface standard, Segger and Lauterbach use different hardware and software to interact.

I’ve used JLinkExe command line software (from Segger) to control the debugger, in the case of T32 you will probably need to use Lauterbach’s Trace32 command line software + scripts, such as: https://stackoverflow.com/questions/24883140/controlling-trace32-via-command-line#29424294

Haven’t used Trace32 GUI software for some years, never used the command line.

 

You can probably create a flashing script starting form JLink scripts, you need to:

  • setup trace32 software on your Lava server
  • learn how to use the command to flash your board using a cmm script
  • change JLink scripts with T32 commands and cmm script generation
  • pull request your changes so others can benefit 😊

Hi Kumar, Andrei

 

From the previous lava- mailing list i have seen that you people addressed jlink debugger information as like this :

Can you please let me know, whether the latest lava version can support trace32 boot method instead jlink/cmsis-dac. trace32 debugger tool is designed by lauterbach and it is licensed one. 
I am bit afraid whether this support is available from lava server or not as Jlink support added recently.
https://www2.lauterbach.com/pdf/app_t32start.pdf
We need trace32 debugger support as we are using cortex-M55 processor operations over here. 
I am looking forward your kind support
 
thanks
