HiWe are using SEEED studio 102110318 module which uses STM32MP157CAC3 processor. We want to know if there is any way we can keep processor pin PD13 pin to low state in suspend state. We want the pin to maintain low state while in sleep mode. We have...
Hi,we are using a coin cell to supply the internal RTC of an STM32MP157 when our system is unpowered.This works as expected - as long as the external supply is off. As soon as the system is powered on, the battery is discharged with >20µA.Observing t...
Hi Everybody,I would like to completely boot kernel 5.10-dunfell (last year) from a 64MB dataflash (nor0). No mmc0 or nand0. Compiled the correct DTS with TF-A, U-Boot and kernel, I would like to use the following TSV for STM32CubeProgrammer:#Opt ...
Custom PCB, STM32MP157C chip. Linux 5.7.10. Buildroot build. No issues - Linux boots to console prompt without trouble, no errors. I can view device registers and all memory regions using Segger Jlink via SWD in both SPL and UBoot. Once Linux starts ...
Hallo in our company we use for a large Project a STM32 MP153a microprocessor. Currently I'm trying to write a Device Driver for the TDK ICM42688P Mems Gyro. We have connected the Gyro trough I2C with the Cortex M4 core within the MPU. Both devices a...
Hi @Community member , Is there any common Linux image available for accelerating STM32MP1 based SoM, irrespective of eMMC (JEDEC Version 5.0/5.1 Complying) & DDR3 manufacturer.

hi, i'm stuck starting usbh_hs2 from u-booti can already start usbh_hs1 at boot, in order to load kernel and fs from an usb mass storage. i wish to do the same with usb_hs2, is that possible? is one configuration from DTS or from U-boot source code? ...
Hello All,forgive me if this as an obvious mistake but I'm completely new to TouchGFX. I'm using STM32 MPU, with Cube, FreeRTOS and TouchGFXI have created a page in TouchGFX using the digital clock object, I have created a TickEvent to update the clo...
