Running the code "MP13_BSP_BasicTemplates" in the DDR of the STM32MP135F-DK succeeds，But running the code "UART_Receive_Transmit_Console_A7" in the DDR of the STM32MP135F-DK fails（“USE_DDR” Macros added,Link text has been modified），Errors are as foll...
Hi,I am using a STM32MP151AAA3 and i need to control an RGB LED via PWM control (something like the WS2812B). I was looking into the PWM driver options for Linux side control and can't find options for PWM control for specific buffer sizes or anythin...
hello，my custom board use the same ddr as STM32MP135F-DK board. but when I debug the example DDR_Init_A7.erro occus when verify data in address 0xc0000000 + 0x80。as show in picture.pls help me
Hi!! I have STM31mp157C and I want to use the ADC. I am exploring the available GPIOs and have observed that some are present in both ADC1 and ADC2.For example, according to the datasheet, PA4 can be used with ADC1/ADC2.Is there any difference betwee...
Dear community,I need your help.I'm using a ES8388 Codec on a custom board with STM32MP157 MPU. ES8388 codec connected on i2c1 and sai2. In the codec driver, ES8388 is in salve mode and MPU is in master mode. mclk cannot be obtained.device tree:k...
Hi there, I'm using a custom STM32MP153 board with OpenSTLinux distribution (5.15.24) on it, and I have a problem with the Wake UP. I successfully set PWR gpio to wake up from low power modes. In fact, I can successfully wake from CSleep and CStop m...
Hello everyone, I was attempting to migrate my existing raspberry pi application for GPIO control to the STM32MP157 but I encountered a roadblock. I was using gpiod to drive the pins from the userspace app but the following guide:https://wiki.stmicro...
I have a stm32mp135F-DK and I am attempting to do some GPIO control. My question is where can I find the mapping of libgpiod chip/line mapping to physical pin. I am particularly interested in the mapping to the CN8 pins as I will be wanting to read...
I'm doing a project, that I need a rotary encoder working on cortex-a7 core of stm32mp157.I met problem, my rotary encoder can not work. This is what I have done:1. In kernel menuconfig I have config: use rotary encoder as a build-in module;2. Write...
I am using the SDMMC1 interface without an SD card, utilizing only the data lines. Therefore, the CMD line is not needed, and I have deactivated the CMD pin. However, the HAL_SDMMC library sends CMD data and expects a response from the SD card, causi...
