Re: [U-Boot] powerdown can't work (mx28)

2012-07-30 Thread alex
Hi:
  If the voltage of battery is below 3.6v, the system still can be startup, and 
do you think it is right?  The function mx28_powerdown is meaningless.

The poweroff function in kernel can work. The similar code can be found in 
bootlet from FSL, and it also can work . After poweroff the system, press 
pswitch key and the board can startup.

Dear alex,

  Hi:
   I find that mx28_powerdown function can't power down mx28, and continue
 to load kernel I don't know whether this issue is on your side. My
 board is changed frommx28evk. Was mx28_powerdown function tested? Best

I think this question was here already.

What do you expect that function to do? It won't do anything like ACPI 
powerdown 
you know from PC (it's not even possible on the hardware I guess).

The function should probably be adjusted and some for(;;); added at the end, 
but that's probably it.
