Issue with running from SRAM

This is a new issue involved in running from SRAM. I recently posted an issue:https://community.st.com/s/question/0D50X0000BDnc5pSQB/stm32f7-uart5-issueand this is a second, possibly related issue.The software I am writing is a Built-in-Test and boot...

We are using PMIC of STPMIC1A, here Buck2 input is 5V and ouput is 1.1v (default value) as mentioned in datasheet. In LDO3 input is VDD_DDR i.e,1.1v and output is VTT_DDR i.e,1.8v(Default value). How is it possible when using LDO?

ST32MP157C-DK2 low power operation

I've been trying to reduce power consumption of the STM32MP157C-DK2 board and have a very low power linux platform. But the power consumption seems somewhat agnostic of power rails and clock rates. For example, I removed the LCD, I boot to u-boot, th...

Verify Voltage Level on FMC

I've spent some time looking over the STM32MP15x hardware manual but cannot confirm that the FMC levels (in SRAM mode) are 1.8v. Can this be confirmed or corrected please?

OpenAMP_TTY_echo_wakeup example prevents A7 processor from going into low power mode.

I'm trying to develop an application that puts the A7 into a low power mode and only uses the M4 to do some basic processing. I'm starting with the OpenAMP_TTY_echo_wakeup example. In the example it says to issue the following commands:echo "*delay" ...
