Dear STMicroelectronics Support Team,I am working with the STM32MP257F-DK board and using OpenSTLinux. In my setup, I am only using the Cortex-A35 (MPU) without any firmware running on the Cortex-M33 (MCU). I am trying to enable USB OTG functionality...
Hello STMicroelectronics Community:I would like to ask how to burn the system without using STM32CubeProgrammer. My chip is stm32mp135-AAE3. Thanks,Ivy7
My board (STM32MP135D) useTIM2 to count the external clock.PE15 cannot work properly, but PA15 works normally. // ok tim2_pins_mx: tim2_mx-0 { pins { pinmux = <STM32_PINMUX('A', 15, AF1)>; /* TIM2_ETR */ }; }; // not work tim2_pins_mx: tim...
Hello STM32 Community,I’m currently working with the STM32MP135D-FK (Boyard) board and trying to build a Weston image using a custom machine configuration. I’m following the official guide: :link: https://wiki.stmicroelectronics.cn/stm32mpu/wiki/How_...
Dear STMicroelectronics Support Team,I am currently working with the STM32MP257F-EV1 evaluation board and have encountered a discrepancy in the user manual (UM3359, Rev 2, October 2024) concerning the GPIO mapping of the USER2 button.In Table 8 of th...
Hi,I've lost the power brick for my STM32MP15X-EVAL board. It's a 5v-3a barrel connector, but I don't know the polarity and it's not written on the board or anywhere.Does anyone know where I can find a replacement, or the exact spec of the power bric...
