I have a 3rd party SOM (seeed studio Odyssey). When I edit the .dts file in the tf-a-stm32mp1/fdts directory and add: &pwr_regulators { system_suspend_supported_soc_modes = < STM32_PM_CSLEEP_RUN STM32_PM_CSTOP_...
I have tried the following on my DK2 dev board:Connect VBAT (verify that RTC is working as well)Set rtc alarm (30s into future or so)Power off via long press of "sleep" buttonWait for alarm to wake RTC...I have verified that the RTC is using the LSE ...
It isn't clear to me from this article (https://wiki.st.com/stm32mpu/wiki/Clock_device_tree_configuration_-_Bootloader_specific#cite_note-st.2Cstm32mp1-rcc.txt-1) if I can set operating points for my stm32mp157c part. If not am I stuck setting PLL1 ...
From my understanding of the documentation, my steps to lowest power (VBAT mode) on the STM32MP1-DK2 kit would be: Connect Battery to VBATSet BREN in TF-ADisable wake sources other than from PMIC and RTCenter sleep via: "echo mem > /sys/power/state"I...
If I put the system to sleep via the "echo mem > /sys/power/state" mechanism, how can I execute code/script on wakeup event?Thanks,Ben
