Hello,We are designing a custom board with the "STM32MP157FAC1" MPU.Would it be possible to get the die to BGA package pin delays for the DDR3 and the EMMC interfaces ?The AN5122 seems to only have track lengths. Our PCB track layout has some constra...
I have a system (built using yocto kirkstone) working with the bootchain TF-a -> sp_min -> uboot when loaded from the sdcard and from the emmcI have tried to boot into uboot by loading it directly into memory (as a precondition to the use it to flash...
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 We are using timer peripheral in STM32MP157 Cortex -A7 core 0 processor. In this, we enabled TIM2, TIM3, TIM4 in RCC APB1 peripheral enable for MPU set register, now we unable to use these timers (not getting interrupts) in Cortex -A7 core...

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...
