s32k3 secure debug interface?

Hi Nxp,

i've set S32K312 LC to OEM_PROD and secure debug is active. i only got jlink now and have some question :

1. to open the secure debug, is interface JTAG / SWD both available or ONLY JTAG?

2. is there any scripts for jlink to authurize secure debug?

Re: s32k3 secure debug interface?

thanks, use pylink to implement CR auth works.

Hi @victory

1. To open secure debugging, are JTAG/SWD or JTAG ONLY interfaces available? Both JTAG and SWD interfaces are available.

2. Is there any script for jlink to enable secure debugging? I am afraid J-Link does not support secure debugging of applications with password authentication or with challenge/response authentication.
