Hello TI,
I found a new feature about DeepSleep in release note of SDK10.0.
I have some questions for MCU only mode.
What is the current consumption of SoC in MCU only mode?
What is the power supply status of peripheral devices in MCU only mode?
How long does it take to boot from MCU only mode to main domain startup?
Best regards
Chunfu
Hi Chunfu,
What is the current consumption of SoC in MCU only mode?
Refer to the Linux SDK 10.0 measurements: https://software-dl.ti.com/processor-sdk-linux/esd/AM62PX/10_00_07_04/exports/docs/devices/AM62PX/linux/Linux_Performance_Guide.html#low-power-performance
These measurements were ran on the AM62P TI EVM (SK-AM62P-LP). The MCU is not running anything, so the power consumption in MCU Only mode will be dependent on the application running on the core. The IO Rails (DVDD_1V8/3V3 & VDDA_1V8) are system dependent.
What is the power supply status of peripheral devices in MCU only mode?
Please refer to the AM62P Technical Reference Manual Table 6-9 Voltage, Power and Clock Domain Status: https://www.ti.com/lit/ug/spruj83a/spruj83a.pdf
How long does it take to boot from MCU only mode to main domain startup?
Can you clarify what this means? Are you asking the time from wakeup event to Linux resuming?
Best Regards,
Anshu
Hello Anshu,
Thanks for your reply.
Can you clarify what this means? Are you asking the time from wakeup event to Linux resuming?
Yes , I want to know the time from from wakeup event o Linux resuming on MCU only mode.
Best regards
Chunfu
Hi Chunfu,
I will take a measurement and reply back by the end of day tomorrow with the results.
Best Regards,
Anshu
Hi Chunfu,
It takes 80ms to suspend the device into MCU Only mode. Once the device is in MCU Only mode and a wake event triggered, it takes 159ms to resume back to Linux.
Please be aware that these measurements are with the default Linux SDK & can be optimized further by disabling unused drivers. The printing of kernel message tends to increase the latency.
Best Regards,
Anshu
Hello Anshu,
We want to measure Deep Sleep and MCU Only mode's consumption on our side, so I want to know:
1. How to force the SoC enter Deep Sleep or MCU Only mode?
2. How to configure MCU R5F to work as General Purpose Processor or Safety Processor? As I learn from TRM that Deep Sleep mode is not supported if Safety is running.
3. How to confirm the SoC does be in Deep Sleep or MCU Only mode?
4. How to configure the wakeup events for Deep Sleep or MCU Only mode?
Best regards
Chunfu
Hi Chunfu,
Please refer to the Linux SDK Documentation for Low Power Modes: https://software-dl.ti.com/processor-sdk-linux/esd/AM62PX/10_00_07_04/exports/docs/linux/Foundational_Components/Power_Management/pm_low_power_modes.html
1. How to force the SoC enter Deep Sleep or MCU Only mode?
This is documented in the link above.
2. How to configure MCU R5F to work as General Purpose Processor or Safety Processor? As I learn from TRM that Deep Sleep mode is not supported if Safety is running.
Please make a separate E2E thread for this item so another engineer can provide assistance.
3. How to confirm the SoC does be in Deep Sleep or MCU Only mode?
On TI EVMs, there is a LPM_PMIC_EN signal which is connected to a test point to test this. You can also refer to the SYSFW logs to track the TISCI message transactions: 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?tisearch=e2e-sitesearch&keymatch=deep%20sleep%20debug#
4. How to configure the wakeup events for Deep Sleep or MCU Only mode?
This is done in the device tree and documented in the SDK Link above.
Thanks,
Anshu
Hi Anshu,
After reading the content in the link, I have following questions:
1. Can you explain "Device Constraint" mentioned in S/W Architecture of System Suspend more detailed? I want to know the possible options and their meanings, which processes can be set, and is it possible to be set on Linux's user space and how to.
2. What's the meaning of mem/disk/freeze of rtcwake command's -m option, and their difference?
3. Are mem/disk/freeze possible options to /sys/power/state?
Best regards,
Chunfu
Hello Chunfu,
1. Can you explain "Device Constraint" mentioned in S/W Architecture of System Suspend more detailed?
The device constraints are documented in the TISCI User Guide: https://software-dl.ti.com/tisci/esd/latest/2_tisci_msgs/pm/lpm.html#tisci-msg-lpm-set-device-constraint
What's the meaning of mem/disk/freeze of rtcwake command's -m option, and their difference?
I will get clarification on this from the Software development team. Please expect a response by early next week.
Thanks,
Anshu
Hi Chunfu,
For both rtcwake and /sys/power/state, only mem is supported in the Linux SDK. Disk and Freeze are not supported in the Linux SDK. Its possible they may work, but TI cannot guarantee the behavior and cannot provide support for those items on the E2E Forum.
For more information about the generic Linux Power States, see here: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/Documentation/admin-guide/pm/sleep-states.rst?h=ti-linux-6.6.y

Hello Anshu,
We have measured EVM's consumption on our side, 1.440W for MCU Only mode and 0.314W for Deep Sleep mode, both are greater than the references that you provide above.
I want to know:
1. By default in Deep Sleep mode, will the controllers for these 4 wakeup sources be powered off (Real-Time Clock, Main I/O Daisy Chain, USB Wakeup, WKUP UART) ? If any of these controllers is not powered off by default, can I manually power it off?
2. Can I further reduce Deep Sleep Mode consumption by disable some unused function?
Best regards,
Chunfu
wiHi Chunfu,
Please explain how you've measured the power consumption during the low power modes.
1. By default in Deep Sleep mode, will the controllers for these 4 wakeup sources be powered off (Real-Time Clock, Main I/O Daisy Chain, USB Wakeup, WKUP UART) ? If any of these controllers is not powered off by default, can I manually power it off?
No, they won't be powered off, but you will not see significant power savings if you do turn them off.
2. Can I further reduce Deep Sleep Mode consumption by disable some unused function?
Disabling unused functions like drivers will only change the latency on suspending and resuming, not the power consumption. You can put the unused IOs into a reset state to reduce the IO power consumption.
Best Regards,
Anshu
Hello Anshu,
1. Here is how I measure the power consumption. Pleasure point out if there any step is improper.
The SDK version I used is 09.02.01.10 and the default image is used with nothing changed.
During the test, only FTDI Micro-USB and Power Only USB-C of EVM board are connected. My power supplier has the ability to show real-time voltage and current.
The commands for entering Deep Sleep mode are
echo 250 > /sys/devices/system/cpu/cpu0/power/pm_qos_resume_latency_us
devmem2 0x43018080 w 0x15
echo mem > /sys/power/state
After these commands I can see this print from MCU: [IPC RPMSG ECHO] Closing all drivers and going to WFI ... !!!
The commands for entering MCU Only mode are
echo 100 > /sys/devices/system/cpu/cpu0/power/pm_qos_resume_latency_us
echo enabled > /sys/bus/platform/devices/79000000.r5f/power/wakeup
devmem2 0x43018080 w 0x15
echo mem > /sys/power/state
After these commands I can see this print from MCU: [IPC RPMSG ECHO] Press a sinlge key on this terminal to resume the kernel from MCU only mode
2. Can you describe more detail how to put the unused IOs into a reset state?
3. How to accurately measure the resume time?
Best regards,
Chunfu
Hi Chunfu,
Based on the data collected, its likely measuring the power of the entire board, not just the AM62P SoC. This would lead to a larger than expected power consumption.
2. Can you describe more detail how to put the unused IOs into a reset state?
This wouldn't change much at the moment (1-2mW) so lets skip this for now.
3. How to accurately measure the resume time?
Refer to this E2E FAQ: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1386942/faq-am62p-how-to-measure-wakeup-latency-for-low-power-modes-on-am62x-a-p
Best Regards,
Anshu
Hello Anshu,
Thank you so much about the answers to power consumption, but I still have some queries about wakeup latency.
1. I have measured the wakeup latency of MCU Only mode, which is about 317ms and is much higher than 133.9ms shown in the link you provided. My measurement environment is the same. What may be the main reason?
2. Is there a way to measure MCU R5's wakeup latency from Deep Sleep mode?
3. I have trouble waking up the SoC from Deep Sleep mode. It seems that the WKUP UART and USB wakeup methods are disabled by default. Can you provide me detailed references for enabling WKUP UART or USB wakeup methods？
Best regards,
Chunfu
Hi Chunfu,
1. I have measured the wakeup latency of MCU Only mode, which is about 317ms and is much higher than 133.9ms shown in the link you provided. My measurement environment is the same. What may be the main reason?
I'll need to look into this further. Please allow some time for a response on this item. Just be aware that the default Linux SDK is designed to enable most features (and their respective drivers) so the resume latency is not optimized by default.
2. Is there a way to measure MCU R5's wakeup latency from Deep Sleep mode?
There is not a readily data, but you could try a simple test of measuring the latency between Deep Sleep & MCU Only. In theory, most of the delta would be the MCU and its peripherals.
Can you provide me detailed references for enabling WKUP UART or USB wakeup methods？
Information about enabling wakeup sources are in the Linux SDK Documentation: https://software-dl.ti.com/processor-sdk-linux/esd/AM62PX/10_00_07_04/exports/docs/linux/Foundational_Components/Power_Management/pm_wakeup_sources.html
Best Regards,
Anshu
Hi Anshu,
I have already read Wakeup Sources section and tried before I asked the 3rd question. I can't wakeup the SoC from Deep Sleep mode by pressing any key press on the WKUP UART terminal or by plugging or unplugging a USB device. Help me solve the problem.
Best regards,
Chunfu
Hi Chunfu,
Is this being done on a TI EVM or custom hardware?
Can you provide the suspend logs?
Best Regards,
Anshu
Hi Anshu,
It is done on a TI EVM board.
The attachments are the logs from Main/WKUP/MCU UARTs.
Best Regards,
Anshu

Hi Chunfu,
First, lets try to use RTC wakeup to make sure that its able to suspend and resume without any problems. Instead of 'echo mem /sys/power/state', use '
rtcwake -s 10 -m mem'
If this doesn't work (meaning it doesn't suspend and then resume in about 10 seconds), this means there is an issue during suspending. You can refer to this E2E FAQ to further debugging: 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

Hi Anshu,
Sorry for late.
I have tried rtcwake command and the system doesn't resume in about 10 seconds.
Following your guide I get the log. Please help me check and solve the problem.

Hi Chunfu,
From the logs, looks like the last A53 goes into WFI. Are there any other software changes made to Linux?
Thanks,
Anshu
Hi Anshu,
Linux kernel image was built from a clean SDK and I only modified ti_sci_cmd_set_io_isolation() function according to your guide.
1. Do you find any problem from the log?
2. How can I further debug why it failed to wake up from Deep Sleep mode?
3. Have you tried to reproduce the problem on your side? I think it can be easily reproduced by using SDK's default image.
Best Regards,
Chunfu
Hi Chunfu,
I've used the AM62P Default Linux image but I didn't see this issue.
As mentioned in the FAQ, the change to the 'ti_sci_cmd_set_io_isolation' impacts the ability to wakeup. Try removing it.

Hi Anshu,
Thank you very much. I have tried again on my side, and I finally find that it is the command "devmem2 0x43018080 w 0x15" that causes the failure. I can wakeup the cores and measure the recover time now without this command.
1. Can you explain why the command "devmem2 0x43018080 w 0x15" causes the failure?
2. I have measured the wakeup latencies of MCU Only and Deep Sleep mode, which are more than 300ms and are much higher than 133.9ms shown in the link you provided. What may be the main reason?

Hi Chunfu,

It looks like the DM Firmware mask the PMIC_LPM_EN signal rather than changing the signal from high to low. This causes the PMIC to think the SoC is in a different state.
which are more than 300ms and are much higher than 133.9ms shown in the link you provided. What may be the main reason?
The default Linux SDK doesn't optimize the wake up latency. Additionally, each printk statement the kernel makes increases the latency.
