Hi team,I have an STM32MP157 board with a Cortex-M4 processor. I have a simple task, which is to toggle the GPIO at maximum speed with accuracy, ensuring that the clock width does not vary.The maximum toggle speed we require is approximately 15ns bet...
Hi,We are working on developing a custom board that necessitates the immediate activation of a buzzer with a predefined frequency as soon as the board is powered up. We are exploring the feasibility of utilizing the PWM driver in U-Boot to achieve th...
I am trying to create a new board based on STM32MP135D.An error occurs while running u-boot on optee layer.The log below is the log where error occurs. Full log is attached as file. Hit any key to stop autoboot: 0 Boot over usb0! D/TC:? 0 tee_ta_in...
Hi! Is there a way to run unit tests automatically on the STM32MP157-DK2 board? I've managed to flash the device using the STM32 Programmer CLI, but after flashing, I need to manually switch the bootmode to boot from the SD-card.It would be great if ...
Sorry to bother you.I don't need the HDMI chip(sii9022) in my project. So, I first removed the HDMI chip on the STM32P157F-DK2. In fact, I manually removed it with a soldering iron. My SDK and development environment are based on "stm32mp1-openstlinu...
hi,st engineer I am required to conduct Ethernet debugging on an stm32mp157a-st-discovery development board running the RT-THREAD operating system. Within the stm32mp157 Processor Reference Manual, I've encountered such option as follow:10/100M Gigab...
I am using STM32CubeMx to generate device tree:I got these in uboot device tree:&rcc {st,clksrc=<CLK_MPU_PLL1PCLK_AXI_PLL2PCLK_MCU_PLL3PCLK_PLL12_HSECLK_PLL3_HSECLK_PLL4_HSECLK_RTC_LSECLK_MCO1_HSICLK_MCO2_DISABLED>; st,clkdiv = <1 /*MPU*/0 /*AXI*/0 /...
Hi,Currently i am looking for an easy way:to change the device tree, to assign peripherals to the M4 Coprocessor for quasi real time applications. i do have a STM32MP157F-DK2 board for testing and also a board with Debian, which i purchased from a di...
Hi everybody, I'm trying to configure the Wi-Fi module on my custom board (based on the STM32MP153, the Wi-Fi module already tested OK) in Access point mode, and I found the official guide to set hostapd tool to do that: https://wiki.st.com/stm32mpu/...
