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.
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.
