BEAGL-BONE-BLACK: SDK 9.1 Suspend not working

Hi Sabeeh,

I have not checked suspend/resume on BBB with SDK9.1. Let me try it on my setup and get back to you.

Hi Bin,

Could you please provide the fix for us so that we may implement it on our side? We are developing a feature for our linux driver and we would like to test it with the host in sleep. 

Hi Sabeeh,

I will take a look next week to see if I can provide a fix.

Hi Bin,

Any update here?

Sorry Sabeeh, I have not got time on this yet due to other customer escalations. But can you please try to enable kernel config option "CONFIG_WKUP_M3_RPROC" and "CONFIG_WKUP_M3_IPC" and rebuild kernel to see if this resolves the suspend/resume problem? If it doesn't, please attach the boot log.

Thanks Bin,

I'll give this try and reach out if unsuccessful. Thanks. 

Hi Bin,

Unfortunately this did not work. Kernel log attached below:

Hi Sabeeh,

Thanks for testing it. The kernel boot log shows the M3 PM firmware is still not loaded. I will take a look next week.

Hi Bin,

Any update on this? 

I am comfortable debugging a little myself, just need some pointers. For example, should I check if the M3 PM firmware is in the filesystem? If so, where it would be and what's it called?

Hi Sabeeh,

Sorry, I haven't got a chance for it yet. But it would be great if you could debug it.

The M3 firmware "am335x-pm-firmware.elf" is in the filesystem /lib/firmware/ directory. I have checked the sdk default rootfs, it is in there.

"am335x-pm-firmware.elf" is used in am33xx-l4.dtsi, under node "wkup_m3", which has compatible = "ti,am3352-wkup-m3".

"ti,am3352-wkup-m3" points to the driver remoteproc/wkup_m3_rproc.c, which is enabled by kernel config CONFIG_WKUP_M3_RPROC.

So you first might want to enable kernel config CONFIG_WKUP_M3_RPROC, then debug function wkup_m3_ipc_probe() in remoteproc/wkup_m3_rproc.c to see if it fails somewhere.

Is there any update on this issue?  We're encountering the same problem on SDK9

I had all those.

I had been following the guide here:

https://software-dl.ti.com/processor-sdk-linux/esd/AM335X/09_01_00_001/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Power_Management/pm_suspend_resume.html#cm3-firmware

(though its seems out of date even though its tagged as SDK9 -- it seems like its documentation maybe for SDK8)

Are you getting the pm elf loading successfully on boot?

Hi Terry,

Yes, in my test the PM elf is loaded on boot and suspend/resume works fine with rtcwake.

I noticed the SDK documentation you referred configures all the relevant kernel options to '=y', while my patch above set them to '=m'. I just tried to set them to '=y', now the PM elf is failed to load:

root@am335x-evm:~# dmesg|grep pm

CONFIG_WKUP_M3_RPROC=y
CONFIG_AMX3_PM=y
CONFIG_WKUP_M3_IPC=y
CONFIG_TI_EMIF_SRAM=y

So please use my patch to set the kernel options to module. I will report this to our sw dev team to get the documentation updated. Thanks for reporting the issue.

Thanks Bin

Tried that and I can see the firmware being loaded now

Could you share all the init messages, as well as your lsmod? I want to make sure I'm not still missing some module(s)

When attempting to do it, I end up with the following

echo mem > /sys/power/state (I cant do the rtc wake as my platform isn't rtc enabled)

echo mem > /sys/power/state    instead of the rtc wake?

I did it at the end of the log. Since I don't have any wakeup source enabled, the board just got stuck in suspend.

Can you please attach your Linux boot log?

Sorry I saw that at the end after I had replied. Thanks.

Here is my log

This likely is the cause of the problem.

Please see function am33xx_pm_rtc_setup() in drivers/soc/ti/pm33xx.c, this function is called in am33xx_pm_probe(), so am33xx_pm_rtc_setup() failure causes the pm33xx driver probe failed.

You probably have to do something differently about rtc in kernel device tree. I will see if I can replicate the issue on my setup.

How the rtc node in your board dts is configured? I used the following patch to disable rtc on my Beaglebone Black,

diff --git a/arch/arm/boot/dts/am335x-bone-common.dtsi b/arch/arm/boot/dts/am335x-bone-common.dtsi

 };
 
 &pruss_tm {

now rtc is disabled in kernel:

[   21.781347] PM: no-rtc available, rtc-only mode disabled.

the last line of the message above is printed in am33xx_pm_rtc_setup() which directly returns without dealing with rtc. And now I can still suspend:
