i have a question regarding to exit the Low Power Mode on CM4. Is it possible that i can exit the CStop or CStandby Mode via an Rx Messages of the CAN Bus, when the CAN Bus is assigned to the M4. Iam confused because almost every Bus is listed in https://wiki.st.com/stm32mpu/wiki/Coprocessor_power_management as Wake Up Source except the CAN Bus.
I confirm, the HW does not permit that.
See STM32MP15x Reference Manual, PWR section.
