Hello @everyoneI have a OSD32MP1-BRK mpu board. I want to test maximum gpio toggle speed. Currently i used libgpio and using this code i achieved 4.1 us (microsecond) between rising and falling edge of pulses.This is too slow as per our requirement. ...
Hi all,Our product uses an STM32MP153 processor, booting its first and second stage bootloaders (TF-A and uboot respectively) from QUADSPI NOR FLASH. It boots Linux from eMMC. The NOR FLASH we have been using are either IS25LP016D-JNLE or AT25SF161B-...
Hello, I've just migrated from V4.1.0 dev package to V5.0.0 and the LCD SPI ilitek 9486 does not work anymore.Configuration: STM32MP157A-DK1 with 3.5 LCD SPI touchscreen. Starter Package loaded with stm32mp157c-dk2 config. Linux kernel recompiled wit...
Following this:https://wiki.st.com/stm32mpu/wiki/How_to_configure_U-Boot_for_your_board As the default config used stm32_defconfig.At the step make menuconfig disabled PMIC in device driver -> power and enabled regulator power .Though, this causes...

Hello everyone,I am trying to apply the hello world example from stm32MP1 workshop. everything works fine for me. However, when I try to run the application inside stm32mp1 it shows me this message. version `GLIBC_2.34' not found.I tried to install n...
Our board is using STM32MP15 and doesn't use PMIC, when we try poweroff command, it seems to work but after around 30 seconds, the board reset automatically.During this time, I see power consumption just goes down a little bit.Does anyone have same i...
Hello,I was wondering how hard is to convert the simple OpenAMP_TTY_echo (I have it installing the STM32Cube_FW_MP1_V1.6.0 package from STMicroelectronics' web site) to a Makefile driven project.I need it so, because the firmware auto building of my ...
Hello,I'm working on a STM32MP157D-DK1 demoboard and I want to manually start the coprocessor from u-boot.I'm tried to follow this tutorial: MANUAL START The steps that I maked are:1) I generated the code with STM32CubeMx (I selected the board STM32...
