Good morning,
I would like to know if I can disable the JTAG in the STM32MP1. Once my project is finished I do not want this interface to be active.
Is there a way to disable the JTAG/SWD interface with registers/fuses/OTP?
Kind regards,
Andrés

Hi @AGamb.4 ,
Please refer to RM0436 chapter
3.6.6 BSEC debug configuration register (BSEC_DENABLE)
This register allow you to set debug capability by SW.
Either until next reboot through the register or definitely with OTP ( eg close device )

Hi Oliver,
can you explain in more detail how to disable JTAG permanently via the OTP?
Can this be done via linux userspace?
We are using a STM32MP153.
Best Regards
Jan
