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...
I have an STMP157F-EV1 and I have followed the instructions here to download and program the starter package. Everything works as best I can tell except the remote console hangs just after the initial login messagestm32mp1 login: root (automatic log...
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/...
