Hi Julián,
yes I tried to follow "Q&A of S32K1x FreeMASTER JumpStart Project", but everything is not working properly. In the "4.5 Set Up Debug Configuration" chapter, the "Apply" button is not active, only the "Debug" button is accessible. When you click on it, an error message appears.


When I proceed:

Click on "Yes":

it seems that we can debug (Run, Suspend, Resume, Step Into, Step Over, Step Return, Terminate… are available), but we do not have access to the source files, it is not viable. I don't know where the indicated path is found ("D:\GIT\033_jumpstart_sw\S32K142_EVB_JumpStart\S32K142_EVB_JumpStart_Firmware\Debug_FLASH/../Sources/main.c"), I looked in the paths specified in the project properties, this path is not specified anywhere, and it does not appear in the source files (according to what I could find).
Yes, I updated "S32 Design Studio for Arm® v2.0 Update 2 – S32 SDK 0.8.5 EAR & MQX", here are the installation details:

I reconfigured the baud rate to 115200 as indicated in chapter 4:

and then I clicked Generate Processor Expert Code:

The problem is still the same.
I had already read the community posts, but the only information that seemed interesting to me would be a command line exceeding 8192 characters and that the GNU ARM Eclipse build tool would have to be updated. The proposed version seems obsolete. I don't know how to check which version I'm currently using and I don't know exactly what to update.
Best regards.
