Included in the S32DS for ARM is a set of example projects, which include one called 'hello'. This example shows a basic application which activates an LED when a button is pressed on the S32K144EVB-Q100 evaluation board. The S32K SDK is not used in this example.
In this HOWTO, we will show how to load the project into the workspace, build, download to the target, and run debug.
1. Create Project
a. File -> New -> New S32DS Project from Example
OR from the Dashboard
b. Select S32DS Example Projects -> S32K144 -> hello
2. Examine the code
a. Locate the project in C/C++ Projects view
b. Expand 'hello', then 'src'
c. Double-click on 'hello.c', to open the file in the editor
3. Build the project
a. Click to select hello project, this is to ensure that the tool knows which project you wish to build.
b. Click Build button. By default, the standard 'Debug' build configuration will be used. Projects created using either the New S32DS Project from Example, or New S32DS Project wizard are setup with 3 build configurations: Debug, Debug_RAM, and Release. The 'Debug' configuration contains settings to build the project with the lowest compiler optimization setting and to occupy the Flash memory space on the target. The 'Debug_RAM' configuration is very similar to the 'Debug' configuration with one exception. It is set to occupy the RAM memory space on the target. The 'Release' configuration will build the project with the highest optimization setting and to occupy the Flash memory space on the target.
c. From the console tab, the build status output is displayed. Check here to confirm the build completed and there were no errors.
4. Setup Debug Configuration
a. Click Run -> Debug Configurations… OR from the Debug button menu
b. Expand the 'GDB PEMicro Interface Debugging' group.
c. Select the configuration which matches the build configuration you just used to build the project. For each build configuration generated by the new project wizard, it also generates a matching debug configuration.
d. Select the Debugger tab. The debug configuration was created with the 'PE Micro GDB server' option selected, but there are several hardware options for this. Select the option which matches your hardware setup. For example, for the S32K144, most likely you have the standard evaluation board, which has OpenSDA integrated. In this case, you would use the OpenSDA interface option. For other MCUs, you may have hardware which requires the USB Multilink or Cyclone.
e. Click Refresh to ensure the correct port is selected.
5. Click Debug to start the debugger launch sequence. It is not necessary to click on the 'Apply' button unless setting changes are being made without intention to launch the debugger. The scripts behind the Debug button include the actions of the script behind the Apply button.
6. When the launch sequence completes, the application is executed until the start of main(), where a breakpoint was automatically set.
7. It is now possible to run or step through the code, view variables and registers.
8. Click Resume and when Button 0 is pressed, the LED will turn on as Blue, and when Button 0 is released, the LED turns off.
9. To end the debug session, click the 'Terminate' button. It is a good idea to also click on 'Remove All Terminated Launches', before starting another debug session.
Hello Mike,
I am trying to debug the same project in the same manner mentioned above. Till Step 5 I am following the same steps but when I am clicking on debug one popup is issue is coming which is given below.
----- An internal error occurred during: "Semihosting process monitor job.".
----- java.lang.IllegalThreadStateException
Can you please provide your feedback what is this problem about. Thanks in advance.
Thanks & Regards,
Harpal Singh Jaswal
Hello Harpal Singh Jaswal,
To better diagnose this issue, we will need a few additional details from you. Could you please provide the following:
1. The version and build of S32 Design Studio you are using
2. The name of the example project you are attempting to debug (you indicated you were following the HOWTO, but we need to confirm)
3. Any Console window output which is relevant to this error.
I also ask you to try disabling the semihosting. This can be done easily from the 'startup' tab in the Debug Configurations menu for the debug configuration you are attempting to excute. Likely 'hello_s32k144_Debug_RAM'. Uncheck the box next to 'Enable semihosting'.
Since the semihosting feature is not used in this example project, it should not affect the debugging experience but should eliminate the error preventing your progress. It is possible you have a conflict between the resources used by semihosting and some other process executing on your PC.
Please reply with your result.
Regards,
Mike
Hello Mike,
Thanks for your comments.
Please find the details given below.
1. The version and build of S32 Design Studio you are using--------->> I am Using Version 2.0 and version 1.3 (for both version same issue is coming)
2. The name of the example project you are attempting to debug (you indicated you were following the HOWTO, but we need to confirm)-------->> I am attempting S32K144 " Hello" project
3. Any Console window output which is relevant to this error.------>>Semihosting Console window
And you suggested to disable semihosting, after disabling semihosting "Launching: Initializing debugger services" is getting stuck at 62% and it is not progressing. And one more thing I want to add in my previous comment this same "Launching: Initializing debugger services" was getting stuck at 62% only. Please find the below snapshot for reference.
Thanks & Regards,
Harpal Singh Jaswal
Hello Mike Doidge and Harpal Singh Jaswal,
I have the same problem (stuck at 62%). I use the latest S32 Design Studio (2018.R1) with S32K146EVB. I updated the OpenSDA Firmware.
Please any suggestions. Thanks
Alex
