As the title says, the STM32G47 PA9 pin appears to be set high in boot mode opposed to pulled high though a resistor which is states in AN2606. This is becoming a problem because it introduces negative behaviors in our design when we try to reprogram...
Hello guys.I designed a custom board around the STM32F411CEU6. On this board, I have a switch and a screw terminal header, both of which are intended to be used has GPIO inputs. However, with both I've had a struggle working with GPIO inputs and inte...
I have been struggling with this chip for a few days now. I have code up for the STM32F072, and the STM32F100 series chips, but the GPDMA in the STM32U535 is baffling me. And no, I am not a big fan of the product notes for the GPDMA, while I've gon...
The codebase is generated by CubeMX and now I'm facing issues during debug.debug method is SWD using ST-LINK V2.In debug mode, after resume fron HAL_Init(); , the code will crashed into system memory zone and have no debug information.Break at addres...
Hi, I'm seeking some advice on using a STM32U5A5 in USB device only via a USBC connection.Any previous USB "device only" designs I've worked on only required connections to D+, D- and ground to communicate. These designs have been USB2x.The U5A5 has ...
Dear ST Support Team,I am developing a USB-based device using the STM32H755 microcontroller.In order to ensure proper identification of the device on host systems, I would like to requestthe allocation of a unique USB Product ID (PID) under STMicroel...
Hi,I am using STM32H7B0Since it has only 128KB flash, I will need to use an external flash to run code. There will be a "host" mcu to control this (with BOOT0 / NRST pin control).I am wondering is it possible to use the built-in ROM bootloader (in sy...
Hi, I'm trying to communicate two microcontrollers (STM32H503CBT6 and a NUCLEO-H503RB) via FDCAN but the STM32H503CBT6 is not sending any messages.Both have the same configuration, but the NUCLEO-H503RB can send (I have checked it with an oscilloscop...
Split from this thread. thanks to @Ozone @Karl Yamashita, this afternoon I have tried to extend can2.0 to canfd with my project of stm32g474vet6. I found some strange things, I think there may be a bug of stm32g474vet6 fdcan module. I modifed the FD...
HelloI am using NUCLEO-G474RE board to sample voltages from the the Battery management board. In the PCB board, I have opamp voltage divider to step down voltages around 24Volts to 2.5V level to be read from the STM. Please refer to the voltage divid...
