Hi,
When blowing the SJC_FUSE on an i.MX RT1060 two things seems to happen:
While this is OK, I'm wondering if disabling the JTAG interface on the MCU also disables any SWD interactions?
Thanks,
Daniel

Hi @MulattoKid ,
Please kindly refer to this pic:
SJC_DISABLE negates both lines, so both are blocked. Either JTAG/SWD or even test control.

Hi @Gavin_Jia,
Thanks for confirming!
Out of curiosity, where is this picture from?
Kind regards,
Daniel
Hi @MulattoKid ,
It is from AN12419: Secure JTAG for i.MXRT10xx.
ANs related to security features now require an NDA and a permission request to access them.
Best regards,
Gavin
Thanks!
