I would like to ask about PWD_OFF bit in HW_POWER_RESET register of i.MX28.
My customer saw that PWD_OFF bit field of i.MX28 could be 1 or 0 after u-boot was boot-up on their custom board.
That is, PWD_OFF bit seems not to be stable after uboot started.
In my understanding, the PWD_OFF bit is not affected by any hardware status.
The PWD_OFF bit is changed only by writing the register by software.
Is it true?
