HIWe have purchased few STM32H757 Eval board for initial evaluation. We received the boardsWe have generated code using STM32CubeMX and added just GPIO configs.(PK3,PK4,PK5 as outputs) and flashed code. it was working. we disconnected powersupply and...
Hello, NUCLEO-F411RE JP5 in E5V reset When my F411RE board is powered with 5V, I have to press the reset button to start it. Why doesn't it start? Thank you for your help.
Hi, I am working on the STM32N6570-DK board using the Load & Run boot mode.XSPI2 is used to interface the external flash (boot device).XSPI1 is used to interface an external PSRAM.The FSBL is loaded by BootROM and runs from internal SRAM.The FSBL ini...
I am currently working on a new hardware design using the STM32U575VIT6 (LQFP64, 10 × 10 mm) microcontroller.I would like to request:Reference schematics and layout guidelines for STM32U575 in LQFP64 packageRecommended power supply and decoupling cap...
Hi ST, I'm looking for STM32 boards that are permitted for end-product usage. In particular, I find Nucleo wonderful but my understanding is they are not to be distributed in the product. Does ST offer any comparable SBCs to Nucleo that can be essent...
I have an STM32L4R on a custom PCB. I am able to flash firmware using CubeProgrammer/CubeIDE to it via an ST-LINK SWD connection as well as a DFU Bootloader via a USB D connector. I have a makeshift connection between the USB D connector to a USB C c...
I have configured WWDG Timer in CM7 of Stm32H747I-Disco and configured WW1RSC=0 in RCC global control register (RCC_GCR) for CM7 Reset only instead of system reset.Issue:HAL_WWDG_EarlyWakeupCallback is getting called before watchdog Reset. but afrer ...

Hi, Please suggest STM32L562 UFBGA-132 Fanout guidelines.I looked into STM32L562E-DK design files for fanout, in which signals are routed in top and S1 layer but there is not via details for layer transition from top to S1. Here attached the fanout f...
Hi everyone, I’m trying to use the STLINK-V3MODS Bridge GPIOs (GPIO0–GPIO3) as digital outputs, but none of them show any voltage change at the pins — not even in Open-Drain mode with an external pull-up. All API calls (InitGPIO / SetResetGPIO / Read...
