Hello,I have created my own board in zephyr (using STM32U575).Now I would like to configure the power mode pins (CSLEEP, CDSTOP, SRDSTOP ) in the devicetree of the board.I have therefore implemented the configuration for the pins in the .dts file: &p...

Hello,In the example projects for LPBAM from ST, it is necessary to switch the RAM address to the SRAM region. This is because LPDMA has in Stop2-Mode only access to SRAM4.If I also want to use the RAM, which part of LPBAM (or maybe other parts) must...

Hello,I am using STM32U575 and would like toimplement a PWM output. This should also work in Stop2-Mode.Clock for the LPTIM is LSE. It works with LPTIM1 and 3 without any problems.To generate a PWM in Stop2-mode, I use the LPBAM with LPDMA. Now I wou...

How can I do this?Are any changes necessary in the soc driver?

Hello,In this document there is the following statement:To do so, In the STM32CubeIDE, in Project Explorer > Debug, go to the STM32U575ZITXQ_FLASH.ld and configure the RAM ORIGIN = 0x28000000 and the LENGTH = 16 Kbytes The consequence of this is that...

In the first table of your post, LPTIM1/2/4 are named for autonomous mode in Stop 2 mode.Shouldn't that be LPTIM 1/3/4? In the second table at LPTIM4 there is no autonomous mode available?In relation to the table above, this would be a different stat...

Is there an error in the reference manual (RM0456, page 2465) or how is the line "Autonomous mode" to be understood?
