Hello,I'm working with the STM32MP15 and have found a problem with USART1 during the boot process on a secure boot enabled (TZEN) hardware. The system freezes when U-Boot tries to reset USART1.The problem is with the RCC_APB5RSTSETR register (0x188)....
Dears,I use STM32MP151FAD3 together with STPMIC1. Nowdays I monitored the voltage of vddcore and found it's not stable shown as below.Mostly it's around 1.2v while sometimes it's up to 1.33v .Referring to documentation, I guess it's casued by dynamic...
Hello,I need to change the SD card interface voltage on stm32mp157f-evl board.As per my understanding we can control this via uSD_LDO_SEL, it can be 2.9volts or 1.8 volts.I need to change to 1.8 volts, how can one control this one via software?Warm r...
On STM32F4 has this and it is very easy to use. Does STM32MP15 -M4 MCU have same one?
Hi, we make custom board base on STM32MP15 and without PMIC and have problem with power off command.Does anyone know any document or hint about this? All research we have found always include PMIC.
Hello, i'm currently working on the stm32mp135f-dk with the kirkstone yocto version for layers provided by st. I'm trying to double all fs partitions (rootfs bootfs and userfs) to implement a software update mechanism with an active set of partitions...
hi experts i am not sure this is a right place to use and not good at English please be generousi am not good at linux , i read a wiki "STM32MP15 RAM mapping" and googled some informationi use kernel and u-boot from developerPackagei have no pl...
Hi there, I am working on an OSD32MP157F custom board inspired by STM32MP157F-DK and Octavo Red boards. The pinout is very similar to the stm32mp157f-dk with the main difference that the Murata LBEE5kL1BX-883 is connected to sdmmc3 instead of sdmmc2 ...
Hi, we need a buffer about 200KB on CM4 MCU (STM32MP153)We change the linker file as below, that allow 256KB heap (combine SRAM2 and SRAM3)But every time the buffer has more than 0x30000 (192KB) then it is failed, seem we can't combine SRAM2 and SRAM...
I would like to use the Murata Wi-Fi/BT combo module 2BC on STM32MP1.Is it possible?If it is possible, I would like to know how to integrate 2BC on STM32MP1. I understand following.- Murata 1DX are mounted on STM32MP1 evaluation board.- Murata has th...
