    Hi Naresh,

    For deep sleep, the timer peripheral is not supported yet, but the RTC is.

    Here is the documentation for entering Deep Sleep using the RTC as the wakeup source: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_00_00_03/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Power_Management/pm_wakeup_sources.html#rtc-real-time-clock

    Hi Anshu,

    ability to deep sleep CPU, and wake up on timer event/RTC event .

    actually my RTC not working , not tested this yet . i will reply it once i tested through RTC wakeup event

    how to check whther CPU went into deep sleep or not ?

    Thanks,

    Hi Naresh,

    Are you using custom hardware or TI EVM?

    TI EVMs have a test point that will tell you if the device is asleep by measuring the PMIC voltage: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_01_00_08/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Power_Management/pm_low_power_modes.html#deep-sleep

    The other way is to check the Deep Sleep logs to make sure the full sequence is followed.

    Thanks,

    Anshu

    Hi Naresh,

    Thanks for the information. Can you share the logs of when the device goes into deep sleep?

    Here is the link to the documentation about the low power modes: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_00_00_03/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Power_Management/pm_low_power_modes.html
    You can see the expected logs of a device in deep sleep.

    Hi Naresh,

    The error seems to be in the RTC driver which is linked here: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/drivers/rtc/rtc-abx80x.c?h=ti-linux-6.1.y#n165

    You mentioned before that your RTC was not working. Do you have an update on that?

    Thanks,

    Anshu

    Hi Anshu ,

    Still issue RTC issue is not resolved.

    Meanwhile , could you please help me how to wake up from deep sleep once it went into deep sleep  (please help me witth steps)

    Is it possible to wake up it using internal /external wakeup ?

    Thnaks,

    Naresh

    Hi Naresh,


    You will need to add the device tree overlay which are shown in these steps:

    1. Compile the device tree overlay (k3-am625-sk-mcu-gpio-wakeup.dtso)

    You can follow these instructions on compiling device trees: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_00_00_03/exports/docs/linux/Foundational_Components_Kernel_Users_Guide.html#overview

    2. Add the device tree overlay to dts folder & uEnv.txt: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_00_00_03/exports/docs/linux/How_to_Guides/Target/How_to_enable_DT_overlays_in_linux.html

    3. After saving the changes, boot the device. Run cat /proc/interrupts. You should see the names of the wake up sources that were added in the overlay.

    4. Put the device into deep sleep. Assuming its successfully into deep sleep, you can ground mcu_gpio0_16 to wake it up.

    There are other wakeup sources as seen here: https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_00_00_03/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Power_Management/pm_wakeup_sources.html#mcu-gpio

    Can you explain what you mean by this?

    I added mentioned changes in dts , i found mcu_gpio in /proc/interrupts.

    as we see , MCU GPIO pin is registering in /proc/interrupts ,so for wake up what should we do . 

    if suppose CPU went into seep sleep mode , then do we need to ground the MCU_GPIO pin 16  to wakeup ? what can we obsreved after grounding the MC_GPIO_16 pin ? how come to know whether CPU  is wakeup from deep sleep.? 

    root@am62xx-evm:~# cat /proc/interrupts 

    269: 0 GPIO 16 Edge -davinci_gpio MCUGPIO

    243: 0 pinctrl 456 Edge 2800000.serial:wakeup

    Please help us on this , we are newbies for deep sleep feature.

     

    Thanks,

    Hi Naresh,

    Good to know that the RTC issues were resolved.

    0xFF wakeup source refers to an invalid wake up source: https://downloads.ti.com/tisci/esd/latest/2_tisci_msgs/pm/lpm.html#tisci-msg-lpm-wake-reason

    How many A53 core does your custom hardware have? This would be good to know if since it doesn't seem that the CPUs are turning off. I'll try to find more information on the CPU error.

    Can you setup SYSFW trace following this FAQ: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1323581/faq-processor-sdk-am62x-a-p-how-can-we-debug-deep-sleep-on-am62x-am62a-am62p-using-sysfw-trace? This will help with understanding what the DM Firmware is doing.

    Hi Anshu ,

    AM631 SOC we are using  on our customer board.

    AM6231 has 1 core only.

    evm

    is this command , placed the device into deep sleep mode , can u please confirm ? here we just put device into deep sleep mode , not waking up the device ,am i correct ?

    Naresh Nakka said:

    This command also for putting device into MCU only mode right ? here not able to going to mcu mode right ?

    Please  help us on this issue . Thank you .

    Hi Naresh,

    Yes, echo mem > /sys/power/state is correct. The device is not asleep as shown in the logs so wakeup will not work yet.

    Thank you for mentioning there is only one A53 core. The default device trees in the SDK support 4 cores not 1. Have you made any changes to the device tree to disable the other three cores?

    We can use the SYSFW traces to determine where in the sequence the device throws an error.

    Best Regards,

    Anshu

    Hi Anshu, 

    Thanks for your response ,

    Jfyi, CPU0 is only enabled on AM6231 our customized board. 

    made below changes to disable the remaining CPU cores  and disabled GPU subsystem in dts file

    +&main_rti1 {
    + status = "disabled";
    +};
    +
    +&main_rti2 {
    + status = "disabled";
    +};
    +
    +&main_rti3 {
    + status = "disabled";
    +};
    +&gpu {
    + status = "disabled";
    +};
    +
    +&main_rti15 {
    + status = "disabled";
    +};

    cpus {
    + /delete-node/ cpu@1;
    + /delete-node/ cpu@2;
    + /delete-node/ cpu@3;
    + };

    Note : GPU subsystem is not present on AM6231, so we disabled it.

    WORKAROUND SYSFW TRACE 

    • in uboot ,i made below change in "board/ti/am62x/board-cfg.yaml" 
      trace_dst_enables : 0x01
trace_src_enables : 0x1F

    • in Linux below changes we made as below 

                   file name : drivers/firmware/ti_sci.c

                    ti_sci_cmd_set_io_isolation(const struct ti_sci_handle *handle,  u8 state)
                      /*HACK: return without doing anything; required for Sysfw LPM trace */
                +    return ret;

    • compiled the uboot images (tiboot3-gp-evm.bin ,tispl.bin and u-boot.img)  and linux kernel Image

    Hi Naresh,

    For disabling CPUs, can you add the following node?

    &cluster0 {

    /delete-node/ core1;

    /delete-node/ core2;

    /delete-node/ core3;

};

    We've noticed in other testing that disabling the cluster has helped.

    Naresh Nakka said:
    trace_dst_enables : 0x01 trace_src_enables : 0x1F

    Instead use:

    trace_dst_enables : 0x0d
    trace_src_enables : 0x3f

    Naresh Nakka said:

    The trace logs will be seen on the ttyUSB2.

    Hi Anshu , 

    Thank you your Quick support !

    I added cluster node in the device tree to disable the CPUs . 

    I got below logs after issuing deep sleep command and stuck  at  "printk: Suspending console "means that is this went to deep sleep ?

    why it doesnot showing CPU logs then ,

    root@am62xx-evm:~#

    [ 122.529023] printk: Suspending console(s) (use no_console_suspend to debug)

    After above logs then its stuck .....

    so , in order to check MCU Only mode , i power the cycle and issue below commands.

    root@am62xx-evm:~# echo enabled > /sys/bus/platform/devices/5000000.m4fss/power/wakeup

    [ 55.256009] printk: Suspending console(s) (use no_console_suspend to debug)

    then here it is also stucks .....

    At this point we measure the PMIC voltage showing as 3.3 V only.

    From this screenshot , should i tell  from the logs , CPU went into deep sleep partially.

     for full deep sleep , do i need to set this register , => PMCTRL_SYS register (0x43018080) to 0x15). 

    But i could not find this register in my PMIC module "TPS6521903RHBR".

    And on our customized board we are using only  WKUP_UART0 used for some other itnterface.

    we didnt have port WKUP_UART2 for collecting systrace Logs.

    JFYI ,my device tree settings for Deep sleep :

    cpus {
    /delete-node/ cpu@1;
    /delete-node/ cpu@2;
    /delete-node/ cpu@3;
     };

    &cluster0 {

    /delete-node/ core1;

    /delete-node/ core2;

    /delete-node/ core3;

    };

    //WAKEUP Source
    wake_mcugpio1_pins_default: wake-mcugpio1-pins-default {
    pinctrl-single,pins = <
    AM62X_MCU_IOPAD(0x0040, PIN_INPUT, 7) /* (D6) MCU_MCAN1_RX.MCU_GPIO0_16 */
    >;
     };

    //WAKEUP Source

    mcu_gpio_key {
    compatible = "gpio-keys";
    autorepeat;
    pinctrl-names = "default";
    pinctrl-0 = <&wake_mcugpio1_pins_default>;
    interrupt-parent = <&mcu_gpio0>;
    interrupts = <16 IRQ_TYPE_EDGE_RISING>;
    switch {
    label = "MCUGPIO";
    linux,code = <143>;
    gpios = <&mcu_gpio0 16 GPIO_ACTIVE_LOW>;
    wakeup-source;
    };
    };

    &main_rti1 {
    status = "disabled";
    };

    &main_rti2 {
    status = "disabled";
    };

    &main_rti3 {
    status = "disabled";
    };
    &gpu {
    status = "disabled";
    };

    &main_rti15 {
    status = "disabled";
    };

    //PRUSS subsystem is disabled
    &pruss {
    status = "disabled";
    };

    Naresh Nakka said:

    We cannot confirm the behavior (without logs). It could mean that the device is hanging.


    Naresh Nakka said:

    This is not required, but its just a way to check the device is asleep.

    Naresh Nakka said:

    I will check internally if there is a way to change the output location of logs.

    Hi Naresh,

    Can you change SDK versions to Linux SDK 9.1?

    In SDK 9.1, there was a feature allows for the trace logs to be stored in memory rather than through WKUP_UART0.

    Hi Naresh,

    Looks like the logs are stored in R5FSS0_CORE0_ATCM which has a base address of 0x0078000000 as seen in the TRM Table 2-1. Memory Map: https://www.ti.com/lit/ug/spruiv7b/spruiv7b.pdf

    Still trying to see if there are anymore details.

    Hi Naresh,

    Its been a challenging to work around the lack of WKUP UART to get the R5F Trace logs. It should be possible by reading from the R5F TCMA, but the logistics of doing so is still being worked out.

    I will update as soon as possible.

    Just to confirm, is there no possibility of accessing the WKUP UART or /dev/ttyUSB2? If so, then this work around would not be required.

    Best Regards,

    Hi Naresh,

    I've updated the E2E FAQ with the R5F TCMA method of obtaining the logs. Please see here: e2e.ti.com/.../5034765

    Try going through this and let me know if you have any questions.

    Hi Anshu,

    In above screenshot,

    I observed that in board terminal gave deep sleep command .

    and in Host termal trying to accessing the deep sleep logs . But how can we access the /dev/ttyUSB2 port in host machine ?  ttyUSB2 we can access only in board/target terminal only right ?

    Thanks,

    Naresh

    TI__Genius 17850 points

    Hi Naresh,

    /dev/ttyUSB2 is found on the Host machine when the target is connected to the Host via the UART serial connection.

    I thought that you're custom hardware does not WKUP UART as confirmed by Sai. Please correct me if needed.

    I've added a section later in the FAQ that supports the getting the logs from R5F TCMA because your custom hardware does not have WKUP UART.

    Thanks,

    Hi Anshu ,

    Thanks for your Quick response .

    Suppose if i enabled the WKUP_UART0 port on my device .

    so , i need to solder the "uart serial cable"  to WKUP_UART0  port on my device and connected that cable to my host pc . 

    then from host pc ,using minicom tool  i can collect the systrace logs right ?

    Thanks,

    Hi Naresh,

    If you are able to connect a UART Serial Connecting to WKUP UART to your Host machine, you should be able to collect the SYSFW trace logs.

    Hi Anshu ,

    Thank you detialed explanation .

    I made enabled WKUP_UART0 and connected serial cable to host PC .

    Collected hexa logs in WKUP_UART0  window when you run the deep sleep command in main_uart0 debug window , 

    mian_uart0 window :

    Please find the hexa file full logs( for entire bootup logs and deep sleep command issued logs) and corresponding deep sleep logs.

    Please find below logs when only deep sleep command issued .

    => Logs seems to be showing CPU went into deep sleep , please confirm ?

    But how to wake-up from deep sleep  . 

    Could you please check below  debug main_uart0  wakeup source and MCU_GPIO wakeup source showing in /proc/interrupts .

    But If it went into deep sleep mode, what should i do with debug main_uart0 (2800000.serail:wakeup)  in order to come out of the deep sleep ?

    Kindly help on this issue.

    Thanks,

    Naresh

    Hi Naresh,

    It looks like the device is asleep as indicated by the WFI.

    Revert the change to ti_sci.c because IO_ISOLATION function is required.

    MCU_GPIO0_16 is listed as a wakeup source, labeled MCUGPIO. After fixing the ti_sci.c change, you should be able to ground the pin to wakeup.

    You meant to say , should I revert the changes in ti_sci.c file .

     I just added " return ret" line in ti_sci.c file for sysfw logs .

    I will revert theese changes in kernel from ti_sci.c file 

    What about this file   "board/ti/am62x/board-cfg.yaml"  changed ? Should I revert theese changes also ?

    Hi Naresh,

    Yes, remove the 'return ret'. The board files shouldn't matter.

    Yes I'm referring to Deep Sleep.

    HI Anshu , 

    I revert the changes in ti_sci.c file .

    Anshu Madwesh said:
    change

      Not understood this . Physcially should i ground  MCU_GPIO16 pin (D4)  ?

    could you please clearly expalain how to wakeup from deep sleep step by step if you dont mind .

    Thanks,

    Naresh .

    Hi Anshu , 

    I tried wakup source using UART(main_uart0) .

    Below steps i followed .

    • First i did run  uart wake up source script .

    • Then i issued deep sleep command

    after issuing above deep sleep commands, i could not find any logs 

    Then , after pressing the key(any key ) on main_uart0 keyboard , its coming out of the deep sleep .

    But i didnt see any interrupt on 280000.serial:wakeup 

    Please find respected hexa Logs  and correcspinding deep sleep logs

    Please confirm , whether its really coming out from deep sleep by inspecting logs ?

    Thanks,

    Hi Naresh,

    Can you provide the Linux Terminal Suspend Logs?

    Thanks,

    Not getting Linux terninal suspend logs after issueing deep sleep command ( echo mem > /sys/power/state ) .

    After deep sleep commands , it suspending /waiting but not getting logs .

    parallely ,Could you please expain how to wakeup with MCU_GPIO16 ?

    Also , I tried to wakup with the RTC but getting below issue  (is this issue due to  as we are using external RTC ? )

    root@am62xx-evm:/home# rtcwake -d /dev/rtc0 -m mem -s 5
    rtcwake: cannot open /sys/class/rtc/rtc0/device/power/wakeup: No such file or directory

    Hello,

    I was working on a customer escalation. Apologies for the delay.

    I forgot to clarify that using main_uart0 wakeup will not print any logs.


    Naresh Nakka said:

    Connect the pin to ground.

    We don't have documentation for external rtc wakeup, only internal rtc wakeup.

    Thanks,

    Hi Anshu, 

    Do i need to connect "MCU_GPIO16" physically to Ground?

    Naresh Nakka said:
    First i did run  uart wake up source script .

    With "Main_uart0" i did wakeup the CPU from deep sleep. ? Is this correct? Please confirm?

    Thanks,

    Naresh.

    Yes

    When you enter anything in the Linux terminal after deep sleep, does it resume? If it does then, it woke up.

    Thanks,

    After pressing key , it comes out of the wainting/ sleep mode. 

    But i could not see any interrupt on cat /proc/interrupt.
