We are using STM32MP13 with Linux for the A7 and using HAL (no OS) for the M4 Coprocessor. In Linux we configured in device tree the I2S (codec and sound are also configured in device tree). &i2s1 { clocks = <&rcc SPI1>, <&rcc SPI1_K>, <&rcc PLL3_Q>...
Hello,We are using STM32157AAA3 Processor in our custom board.we are trying to ping ethernet in RMII (100mbps)mode in uboot (2023.04) version.we are facing following issues :1. Invalid PHY Interface.2. eqos_probe_failed() -22 No ethernet found (as...

Hi,I encounter a performance issue on the qt5 application on STM32MP135. I build a simple application with three plaintextedit objects showing temperature with 1s period from ds18b20. Everything compiles well and works, but the refreshing temperature...
First I declare the buffer length/* USER CODE BEGIN PD */ #define ADC_BUF_LEN 10000Then I declare the buffer/* USER CODE BEGIN PV */ GPIO_InitTypeDef gpio_init_structure; VIRT_UART_HandleTypeDef huart0; VIRT_UART_HandleTypeDef huart1; uint16_t a...
Hello, i am using an stm32mp1-dk2 board. For using fw_printenv and other uboot tools from user space one must define a "/etc/fw_env.config" file. I can see that the "/uboot.env" file is driectly saved under the root "/" and so i defined the "fw_env.c...
I am not able to launch SPI activation outputs just using datasheet information. I have tried everything and the status outputs do not change. By making use of an oscilloscope, I have checked that the data bytes transmitted (0xAC01, that would entail...
Hi,we're using STM32MP1 for our project. we have connected super cap to VBAT.our expectation is to have VBAT supply power to RTC *alone*. we dont want RAM content to be retained. so that RTC shall remain powered for long time. currently the VBAT is s...
I have done the yocto build, and i used below bitbake command to generated distribution package.bitbake st-image-weston --runall=deploy_archivesBut i have updated the sources now how to clean and rebuild the archives.used board : STM32MP135FEco syste...
Hello, I have an interprocessor communication problem using the OpenAMP_TTY_echo example on the STM32MP157C-EV1 board.I am tring example OpenAMP_TTY_echo, to comunicate between M4 and A7 on the STM32MP157C-EV1 board.I can't find the solution, and I n...
