How can I wake up the system from sleep?

[VincentChen]

Hi,

Does iMX53 support resume from sleep?

After I execute:  echo mem > state ,  the system seems to suspend to RAM.

Shown as below:

root@cpc-105:/# uname -ra
Linux cpc-105 2.6.35.3 #19 PREEMPT Fri Mar 30 18:24:02 CST 2012 armv7l GNU/Linux
root@cpc-105:/# cd /sys/power/
root@cpc-105:/sys/power# cat state
standby mem

[   42.058816] Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done.
[   42.078833] Suspending console(s) (use no_console_suspend to debug)

But how can I wake up the system? Can I use GPIO to wake up the system?

If I execute:   echo standby > state , the system should enter into standby mode.

But it seems no different from suspend to RAM as below:

root@cpc-105:/sys/power# cat state
standby mem
root@cpc-105:/sys/power# echo standby > state

[   51.288891] Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done.
[   51.308906] Suspending console(s) (use no_console_suspend to debug)

Does it mean that standby and sleep are all the same for iMX53?

Thanks for your reply.

Thanks :)

Just for reference, the default way of using no_console_suspend is to add this string to the Boot loader's (e.g. U-Boot's) kernel arguments...

U-boot> setenv bootargs $(bootargs) no_console_suspend

U-boot> saveenv

Hi karre,

If you have any info updated, please share with us.

Thanks,

Ok Thanks,for your reply.

[VincentChen]

Sorry, I haven't tried xorg and don't know how to install xorg.

[i_Mx53]

In my case it is wakeup happening successfully when i use touch and usb mouse.

if i intigrate usb keyboard screen refresh problem is coming.

Now i have tried with lucid filesytem it is working fine as they are using xorg and apm.

Now i have to try with xorg instead of xfbdev.

Please suggest me how to intsall xorg .

Thanks,

Nagaraj

Hi karre,

I think it's usb controller issue on iMX53.

Because when I worked on wakeup from sleep issue on my iMX53 board, I encountered many USB controller resume problems which caused wakeup from sleep failed.

Below I attached several code snippet screen shots I modified to solve my wakeup issues.

[i_Mx53]

This issue is reporting when i intigrate the USB keyboard to xfbdev tiny X server.

The same is reproduced, withe the freescale demo rootfs.if  i pass the keyboard parameters to xfbdev.

I am in confusion this issue is because of xserver or driver problem.

Hi karre,

I found your device took 2.56 sec to wake up from sleep.

[  442.411136] PM: resume of devices complete after 2559.492 msecs

Mine took 11.73 sec as below:

[  115.280984] PM: resume of devices complete after 11732.740 msecs

What a big different !!

Is it because I don't use Power key interrupt to wake up from sleep?

I use UART interrupt to wake up from sleep becuase my iMX53 board does not have Power key, so I use UART interrupt.

When I enter into sleep/standby mode, then I press any key via my console and it will trigger UART interrupt to wake up iMX53 board.

I modified the following code to enable all hardware interrupts wakeup sources instead of DA9053.

static void loco_da9053_irq_wakeup_only_fixup(void)
{
    void __iomem *tzic_base;
    tzic_base = ioremap(MX53_TZIC_BASE_ADDR, SZ_4K);
    if (NULL == tzic_base) {
        pr_err("fail to map MX53_TZIC_BASE_ADDR\n");
        return;
    }
    __raw_writel(0, tzic_base + TZIC_WAKEUP0_OFFSET);
    __raw_writel(0, tzic_base + TZIC_WAKEUP1_OFFSET);
    __raw_writel(0, tzic_base + TZIC_WAKEUP2_OFFSET);
    /* only enable irq wakeup for da9053 */
//vin    __raw_writel(GPIO7_0_11_IRQ_BIT, tzic_base + TZIC_WAKEUP3_OFFSET);
    __raw_writel(0x1FFF, tzic_base + TZIC_WAKEUP3_OFFSET);//vin added 2012/4/11
    iounmap(tzic_base);
    pr_info("only da9053 irq is wakeup-enabled 1\n");

static void loco_suspend_enter(void)
{
    printk("xxxxxxxxxxx loco_suspend_enter hw");//vin added 2012/4/6
    if (!board_is_mx53_loco_mc34708()) {
        loco_da9053_irq_wakeup_only_fixup();
//vin    da9053_suspend_cmd_sw();
        da9053_suspend_cmd_hw(); //vin added 2012/4/11

    }
}

Hi karre,

Please "add console_suspend_enabled = 0;" as below.

It will print more debug message in sleep mode.

void suspend_console(void)
{
    console_suspend_enabled = 0;//vin added 2012/4/9

    if (!console_suspend_enabled)
        return;
    printk("Suspending console(s) (use no_console_suspend to debug)\n");
    acquire_console_sem();
    console_suspended = 1;
    up(&console_sem);
}

[VincentChen]

I don't have USB keyboard on my device. I  just use console via UART port to debug my device.

Linux kernel version is 2.6.35

Hi vin ,

system is entering into standby state by writing the echo mem > /sys/power/state.

When we press the power button it is resuming back successfully.

But my GUI screen is white screen only, not refreshed and no characters are displayed on it.

How you have intigrated the usb keybord into the system.

To intigrate the keyboard i have added the below the Xfbdev in startx file.

Xfbdev -nolisten tcp -keybd keyboard,,device=/dev/input/keyboard0 -mouse tslib,2,device=/dev/input/ts0 -mouse mouse,2,device=/dev/input/mice &

whenever the

-keybd keyboard,,device=/dev/input/keyboard0

above line is there the systems screen is not refreshing after wakeup.

If i  remove the above line from the startx file the resume is happening successfully but sometimes getting crash.

The issue is related to Xfbdev or any wakeup problem.

Please find the log messages when it is entering into standby mode and wakeup.

Hi karre,

Sorry for my late reply, I just got email notification today.

What is your linux kernel version?

Please attach the kernel dmesg log after you wake up from sleep, because I have modified many kernel source which version is 2.6.35 and I want to know where you encountered the problem.

Thanks,

vin

Hi vin,

i have created the /proc entry for power button event monitoring.

when i write echo mem > /sys/power/state

the system is entering into sleep mode.When i press the power button it is resuming but my gui screen is white only .

I am not seeing any characters on my screen.If i remove  the -keybd keyboard /dev/input/keyboard0 from the xfbdev from the startx script it is resuming successfully and my keyboard is not working.

Please suggest me how do i fix this issue.

Thanks,

Nagaraj
