I am trying to use a Segger J-Link debugger with ‘S32 Design Studio for Arm IDE’.
I am using a ‘UCANS32K146’ evaluation board which has a S32K146 processor.
I set a breakpoint as shown...
But the debugger does not seem to run to or stop at the break point, it seems to be in reset ?
Below is a copy of the console messages...

The Segger control panel shows the following...
The LED on the Segger looks to be orange/red (its hard to tell) which means its either in reset or there's a fault.
A screenshot of the IDE during debugging is shown below...
I was expecting the IDE to stop at that breakpoint so I could step through the lines of code.

Thanks Daniel
I installed the correct SDK...
And used the can_pal_s32k146 example and this worked correctly (after a few minor tweaks to the software)...
Thanks for your help
Hi,
Thanks for your feedback.
Since UCAN board seems to have a different connector, could be that the pin mapping of the debugger is not as the UCAN needs it.
Can you help us probe the S32_RST_N signal when you try to use the JLink? Below will be an image of the schematic:
You could probe the signal wherever you have access to. If the RST signal is being controlled by the JLink, then you should see a toggle on the RST signal.
Also, are you using an example for this?
Please, let us know.
I build as shown in the screenshot below (Node_A_Debug)...
The "Main", "Debugger" and "Startup" tabs inside the debug settings is shown below...
I downloaded and installed "S32_SDK_S32K1xx_RTM_4.0.3" and imported the example '\adc_low_power' but this won't even build as it gives the error "/bin/sh: arm-none-eabi-gcc: command not found"...
It shouldn't be this difficult to get example code working on a development board !
Could someone from NXP contact me to arrange a screen share session to help resolve the problem ?
Hi,
Thanks for your feedback.
The SDK that you are trying to import into S32DS for ARM v2.2 is not compatible with that IDE, it is compatible with S32 Design Studio v3.4. That should be why you are seeing that error.
The one that it is compatible with S32DS for ARM v2.2 should be provided with the IDE, image below:
Within the examples provided with the SDK, the following configurations should be provided:
In our specific case, we use the FreeRTOS project as an example. This should be ready to use.
Please, let us know.
Thanks Daniel
