Hello community
In Document "i.MX_6_Linux_High_Assurance_Boot_(HAB)_Users_Guide_201405.pdf",
It have a sequence to put SEC_CONFIG to close in section 4 "Test Procedure".
After write eFuse by echo command,
In chapter 19, it say that "Boot the board again,",
Is this mean that to effect the chip security immediately, it must need a power on/off cycle?
Or it need only reset (POR_B Low cycle) to do that?
To reduce the eFuse write cycle time, customer plan to use "POR_B" cycle for it.
Best regards,
Ishii.

Hi Ishii
you are right, to effect the chip security immediately it is
sufficient only reset (POR_B Low cycle) to do that.
