AM62A7: Unable to Wakeup the Board from deep sleep.

Harsh Shende

Part Number: AM62A7

Tool/software:

Hello,

I am currently using the AM62A7 board for implementing deep sleep functionality. To put the system into deep sleep, I am using the following command:

echo mem > /sys/power/state

For waking up the system, I am using GPIO 40 on gpiochip1, which is connected to a PIR sensor. However, I’ve observed that the board sometimes fails to wake up even after the PIR sensor detects motion and the GPIO is triggered.

Could you please suggest any possible solutions or required configurations to ensure reliable wake-up from deep sleep via GPIO?

Best regards,
Harsh Shende

Hi Harsh,

What Linux SDK version are you using?

How was this pin configured to wakeup in the device tree?

Best Regards,

Anshu

Hi Anshu,
I'm using edgeai 9.2 build.
Below I'm attaching the device tree I'm using for my application
kindly review it
for your reference in this way I'm using this

&main_pmx0 {
	main_uart0_pins_default: main-uart0-pins-default {
		pinctrl-single,pins = <
			AM62AX_IOPAD(0x1c8, PIN_INPUT_PULLUP, 0) /* (E14) UART0_RXD */
			AM62AX_IOPAD(0x1cc, PIN_OUTPUT_PULLUP, 0) /* (D15) UART0_TXD */
		>;
	};
	
	/PIR handled seperately to not affect poweroff sequence
	pir_keys: pir-keys {
	compatible = "gpio-keys";
	pinctrl-names = "default";
	autorepeat;

	pir-gpio {
			label = "PIR";
			linux,code = <KEY_X>;
			interrupts-extended = <&main_gpio0 40 IRQ_TYPE_EDGE_RISING>,   //mcu_gpio0 12 
				<&main_pmx0 0x0a4>;
			interrupt-names = "irq", "wakeup";
		};
	};

if edgeai 9.2 build does not support deep sleep and wakeup which build supports it . Can you help me

Hi Harsh, I am looking into this and will get back to you tomorrow.

In the meantime, you can look at the documentation for Main GPIO wakeup here: https://software-dl.ti.com/processor-sdk-linux/esd/AM62AX/10_01_00/exports/docs/linux/Foundational_Components/Power_Management/pm_wakeup_sources.html#main-i-o-daisy-chain

An example of enabling Main GPIO wakeup can be found in the k3-am62x-sk-lpm-wkup-sources.dtso: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm64/boot/dts/ti/k3-am62x-sk-lpm-wkup-sources.dtso?h=10.00.07

Let me know if any progress is made.

Best,

Kendall

Hi Kendall,

We are currently using the AM62A7 processor and had initially implemented wakeup using a daisy-chain I/O method. However, we encountered an issue where the board runs normally for a while but then fails to wake up from deep sleep. It is unclear whether the CPU hangs or enters a non-recoverable state. Our setup includes custom services and scripts to handle application logic. We're using EdgeAI 9.2,.

Due to the unreliability of the daisy-chain method, we recently switched to using MCU (WKUP) GPIO as the wakeup source. While testing this new method with our application, we noticed the system still sometimes fails to wake up—even when no application is running.

Could you please confirm if there are any known limitations on the processor or with the EdgeAI build? Any insights or recommended solutions would be greatly appreciated.

Thanks & regards,

Hi Harsh,

After some further investigation, there is no EdgeAI build that supports any low power mode.

If you do not need to use EdgeAI, you can try building and installing Linux and U-Boot. For Linux, use the ti-linux-kernel repository on branch ti-linux-6.12.y. For U-Boot, use the ti-u-boot repository on branch ti-u-boot-2025.01. With this configuration, DeepSleep functionality should be supported.

If DeepSleep does not work using the above, you can try removing the TI Linux modules as certain modules might affect DeepSleep functionality.

ti-linux-kernel repository: git.ti.com/.../

ti-u-boot repository: git.ti.com/.../

How to build U-Boot and the Kernel can be found in the SDK documentation under the corresponding section: https://software-dl.ti.com/processor-sdk-linux/esd/AM62AX/10_01_00/exports/docs/linux/Foundational_Components.html

Let me know if this helps.

Best,

Kendall

Hi Kendall,
It is clearly mentioned in the documentation for the 9.2 in power management section about low power modes and from this only I'm successfully able to take my board into deep sleep below I'm attaching link kindly check :-
https://software-dl.ti.com/processor-sdk-linux/esd/AM62AX/09_02_00/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Power_Management/pm_low_power_modes.html

let me tell you my problem once again .
I'm using Processor SDK Linux for AM62Ax 09_02_00 .Now I'm able to put my board into deep sleep perfectly fine. But when we keep it in sleep for sometime and then try to wake it up from the sleep using pir event which is connected to main_gpio0 40 sometimes that was not waking up. I checked the log using UART and that shows something cpu_stall logs for your reference I'm also sharing that logs below. I don't know what's happening but this is affecting our functionality and when this happens we need to reboot the board that we don't want please suggest me some solution for this.
And in above answer you told to remove some plugins and modules can you tell me which modules should i remove ?

Hi Harsh,

For the modules to remove, try removing the ti_k3_dsp_remoteproc by using the following command:

modprobe -rf ti_k3_dsp_remoteproc

If that does not work, could you send a full log starting from:

echo mem > /sys/power/state

You can also enter the following command before sending the system to sleep in order to see logs during suspend:

echo N > /sys/module/printk/parameters/console_suspend

Best,

Kendall

Hi Kendall,
I tried removing the modules,
and put the board in the sleep mode but after some time it hangs(means my board is on but it is not responding to the pir event, I'm using MCU for pir )
and for logs kindly check the above reply in that i had provided logs.
Kindly tell me the reason why cpu is stalling when it is in sleep

Thanks

Hi Harsh,

When I ran a stress test where the system would continuously go into DeepSleep and be woken up by Main_GPIO0_40, I was able to replicate DeepSleep hanging after 1800 iterations. I did not see any logs where the CPU stalled, however.

I am unsure if this bug still exists in Edge AI 10.1, so I will need an additional day to test that. I will get back to you on Monday about the results of that test.

In the meantime, if you have any pointers on how to test to better replicate your system, please let me know. Additionally, could you run the following command before entering DeepSleep:

echo N > /sys/module/printk/parameters/console_suspend

This will may show some additional logs. Then could you send a full log starting from before the entry to DeepSleep?

Best,

Kendall

Hi Kendall,
Thank you for testing from your side and sharing the results.

However, we are still facing the issue — although I am not sure if calling it a "hang" is entirely appropriate. In this state, the system remains powered on, and all voltages are being correctly generated by the PMIC (we verified this by probing).
Despite that, we are unable to wake up the board, and the UART is also non-functional in this state. The only way to recover is by rebooting the system, which we would prefer to avoid, as we are using it in a standalone setup.

Additionally, we tested with loglevel=14, expecting it to provide extended logs or maintain UART output even during sleep. I have captured the logs and saved them into a file, which I am attaching here.
Kindly review the logs and let us know your observations.

This is log file and I'm also attaching last few logs kindly check
and I will provide the logs with
echo N > /sys/module/printk/parameters/console_suspend

Hi Kendall
below im attaching kernel logs which i stored as you mentioned to give the command

echo N > /sys/module/printk/parameters/console_suspend

before going into sleep(systemctl suspend)
kindly check the logs tell me the issue how can i fix this issue so that my system works propery

Thanks & regards

Hi Harsh,

Based on the logs you have sent, it would be worth it to remove any GPIO you are not using since the following warning is showing up for each sleep cycle:

WARNING: CPU: 0 PID: 406 at drivers/gpio/gpiolib.c:3140 gpiod_set_value+0x5c/0xcc

Additionally there are errors from the gpio-keys in every sleep cycle:

gpio-keys trailcam-keys: failed to get gpio state: -16

These errors look like they can be fixed by fixing the device tree. Fixing these errors could at least help narrow down if that is the problem or not.

Also, I looked at the error logs you sent originally again. It looks like there could be a problem with the rtc-ds1307 device. The logs look like there might be an irq not being serviced or a race condition. I would recommend trying your setup without that device if possible to see if the issue is still happening.

Best,

Kendall

Hi Kendall,

I tried the previous suggestions, but unfortunately, they didn't work.

What I did next was switch the PIR connection from the SoC to the MCU. After this change, we tested the setup and it initially worked without any issues. However, during further testing, we noticed that the board occasionally gets stuck for a short time and then reboots on its own without performing any expected action. This has now happened multiple times.

I'm attaching the device tree file for your reference. Could you please take a look and help us identify what might be causing this issue and how we can resolve it?

Thanks,
Harsh

Hi Harsh,

The interrupts-extended and interrupt-names are not needed for MCU GPIO wakeup on lines 431-433. You can change that code to the following and test to see if that helps:

gpios = <&mcu_gpio0 12 GPIO_ACTIVE_LOW>;

If the issue does not go away, enter this command before suspending the system:

echo N > /sys/module/printk/parameters/console_suspend

Then attach the full logs to your comment.

Best,

Kendall
