Question, i.MX28 PWD_OFF bit

Aemj — Mon, 22 Feb 2016 05:21:49 GMT

Dear team,

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?

Thanks,

Miyamoto
