2009-08-13 17:05:19 Problem with Suspend Mem / Hibernate on BF548-EZKIT
Derek Gallagher (UNITED STATES)
Message: 78864
Hello,
I'm using the BF548-EZKIT and I'm trying to put the Blackfin into a Suspend Mem / Hibernate state using the rtcwake tool.
I'm following the instructions at the link below:
docs.blackfin.uclinux.org/doku.php?id=power_management_support
I am able put the Blackfin into a Standby state for 10 seconds using the following command:
rtcwake -s 10 -m standby
However, when I attempt to put the Blackfin into Suspend Mem / Hibernate, the Blackfin seems to begin Susupend Mem and then gets hung up. The command I'm using is the following:
rtcwake -s 10 -m mem
I have read the following thread, but didn't see any clues.
blackfin.uclinux.org/gf/project/uclinux-dist/forum/?action=ForumBrowse&forum_id=39&thread_id=28519&_forum_action=ForumMessageBrowse
Also, I attemped to pull the DDR Clock Enable pin low as the BF54x Datasheet seemed to indicate that it was required (it is not pulled low on the EZ-KIT). See comment below copied from the datasheet.
DCLKE "This pin must be pulled low through a 10kOhm resistor if self-refresh mode is desired during hibernate state or deep-sleep mode."
Has anyone gotten Suspend Mem / Hibernate working on the BF548-EZKIT?
My configuration is the following:

2009-08-13 17:15:15 Problem with Suspend Mem / Hibernate on BF548-EZKIT
Michael Hennerich (GERMANY)
Message: 78865 Hi Derek,
PM is supposed to work on BF54x - And I think we tested things.
I wonder - did you do anything special to the SD/MMC interface - maybe
card inserted?
Can you explain your exact setup?

Hi Michael,
The output i posted was from a default configuration that had been modified quite a bit. To make things easier, I attempted to put the processor into Suspend Mem using default configurations, but it still doesn't work.
I configured the BF548-EZKIT to its out of the box default jumper and switch settings. I did a distclean on the uclinux-distro and made the following mods:
Enabled Power Management Support in kernel
Enabled Power Management Debug Support in kernel
Enabled Verbose Power Management debugging in kernel
Enabled rtcwake tool in user apps
Disabled mtd_utils in user apps (this was required to get around a mtd_utils related kernel compilation error)
Other configurations are:
BF548-EZKIT REV 1.4
U-Boot SVN Tag=toolchain_09r1_rc9
Kernel SVN Tag=2009R1-RC2
uClinux Distro SVN Tag=2009R1-RC2
I've attached the terminal window output, which is slightly different from my original post. The system only goes into Suspend Mem for what seems to be only for a few seconds. It now does not seem to freeze up after it returns to an Active State (mmc errors from original post are now gone). I've also attached the dmesg output.
Below is a snippet of the total output which shows that the system is waking up before 100 seconds.

Michael,
Sorry I forgot to answer your question about whether an SD/MMC card was inserted in my setup. I tried both setups, one with the included 256MB SD card inserted, and one without any card inserted - both setups failed to go into Suspend Mem state.
Thanks

Try to disable the drivers/input/keyboard/bf54x-keys driver

I've seen something similar on svn trunk - but thought it wouldn't be on

Hi Michael,
Disabling the bf54x-keys driver did fix the problem. That allowed me Suspend to Memory without a problem. Thanks for the help with that.
However, now I'm running into another problem. When I enable MMC/SD/SDIO card support, I'm unable to Suspend to Memory and fully resume. When I execute the 'rtcwake -s 20 -m mem' command, the system does Suspend to Memory and it does resume, but I cannot access the SD card. When I execute the command a 2nd time, the system does not successfully Suspend to Memory. I verified that it does not actually suspend by looking at VDDINT - it's still around 1.3 volts.
I've attached the terminal window output (i outputted dmesg as well), along with a screenshot of my MMC/SD/SDIO Kernel configuration. Looking through the output, it seems like the SD card does not get reinitialized correctly upon resume.
Also, the attached terminal window output shows a case where the SD card was mounted. I've attempted to Suspend to Memory without having a mounted SD card as well, and the same error occurred.
Any ideas?
Thanks in advance,
Derek

I looked at the bfin_sdh suspend resume functions and I can't find
anything that would save and restore the peripheral upon PM transition.
Looks like a bug - I opened this BUG
