SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.

STM32H7 LPTIM5 not waking from stop mode

Hi Forum,

I am using the stm32H743 and trying to keep the power consumption as low as possible by entering sleep or stop mode. I am then using a lptimer to wake the device. Eventually, I will also use the timer to determine how long the device is asleep for.

When I use LPTIM1 this all works fine and the device is woken from sleep or stop mode.

However, I have tried to move across to LPTIM5 and the device will wake from sleep mode, but will not wake from stop mode.

From what I can see in the RM all the LPTIMERS can wake the device from stop mode, but just want to check that I haven’t missed something.
Any ideas are more than welcome!
