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 have imported some example code (libuavcan) into the IDE which builds successfully.
Below are the settings for the debugger…
When I click on ‘Debug’ I get the following error…
When I run JLink.exe it seems to connect successfully….
The programming cable is wired as follows…
How do I get the Segger J-Link to flash/debug code from the IDE to the evaluation board ?

Thanks Robin,
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
Thanks Robin_Shen
I made the changes that you suggested and it now seems to flash, but it still doesnt work.
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...

Starting target CPU...
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.
I don't have this board, so I connect Segger J-Link Plus to J14 of S32K146EVB. Here you can see: I am able to debug it and stop at the breakpoint.
But the debug connecter of UCANS32K146 is P6. I am not sure how you connect it with Segger J-Link, please make sure SWD_DIO\SWD_CLK\RST_N\GND\VTref are well connected.
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.
Please press SW1 and try to debug again. Or you can use loadbin commander. I have attached the bin file of that example.
Best Regards,
Robin

The Segger is connected correctly as shown in the table and diagram below (I have also tested continuity to confirm).
The UCANS32K14 connector P6 is shown on the left and the 20 way header connector for the debugger is shown on the right
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 ?
Thanks Robin,
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
