Program S32K116 NVRAM using SEGGER J-Link

We program our boards with a SEGGER J-Link. We use NVM to hold device defaults. Each customer has their own defaults, well the fussy ones do

How would I go about programming the NVM using the SEGGER J-Link? A guide or even some suggested reading would help. The SEGGER J-Link is Jtag so guess it must be possible.

Hi,

I would recommend contacting SEGGER support.

I don't know what tools you use, but for example, J-Link Commander can program a data file to a specific address in the flash.

I just tried that with an .srec file generated by S32DS2.2 IDE and I could place some constant values to an erased flash sector.

Regards,

Daniel

Thanks.

To double check, does this method work with the FlexNVM?

It works with the FlexNVM as a data flash.
