We are using Murata LBEE5HY1MW WiFi/BT module with a STM32MP157F based custom board, running OSD32MP1 Debian SDK v3.0 (Linux Kernel v5.10-stm32mp)LBEE5HY1MW module is connected to STM32MP157F via sdmmc3 (WiFi) and usart2 (Bluetooth) interface.Due to...
I realize this is probably a pretty basic question but I haven't found a way to have the M4 portion of the firmware startup when the STM32MP1 is powered up. I'm currently using an STM32MP157D-DK1 board, if that helps. I was able to debug the code of...
Hi! I am working with stm32mp157c-dk2 and trying to establish communication between m4 and a7 cores. I analyze standard examples for this purpose, namely OpenAMP_TTY_echo. VIRT_UART initialization is presented here for m4 core: log_info("Virtual UAR...
Hello, I've tried measure period of GPS PPS which is very high accuracy. I'm using TIM5 input capture mode, reset slave mode. The TIM5 CCR1 gives value 208877646 that is wrong because I use high accurate generator for sys clock. The right value is a...
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...
