Given that the S32K344 is a Cortex-M7 part, what debug (JTAG) connector is it using? Pin 7 is populated, so the header is not pinned as a Cortex-Debug+ETM header. Is it the standard ARM 20-pin header (granted, with a smaller pitch)?
JTAG flashing and debugging is not officially supported without a proprietary adapter, which requires an additional “developer” agreement between your company and Audesse. If you require this feature, please reach out to the team directly to start the process.
