Hello ST Community,I’m working with the STM32 Nucleo-N657 board and need a way to execute my application after flashing to external memory without manually toggling the BOOT1 jumper on the board.What I’m Doing Now:BOOT1 jumper is set to HIGH for deve...
Hi;In order to determine exactly the chip type I'd like to read the DBGMCU_IDCODE register. When I try to do this the bootloader hangs. RM0410 44.6.1 says "Only 32 bit access support". I guess the bootloader uses byte access.Is there a workaround?Rea...
Hi Folks,I'm working with an STM32G0B1MCT6. In my application I need to be able to react to pulses with a width of about 5 ns. It seems the only way I could pull this off is with the rising edge detection in the EXTI controller, or some additional ex...
Hi,I’m working on the STM32G491 series. In my current project, the STM32 is configured as an I2C slave and communicates with another processor over I2C.When entering bootloader mode for flashing, the STM32 responds with the slave address 0x5F, which ...
Hi,I’m currently implementing I2C in slave mode using the STM32G491 series. Due to pin constraints, we’re considering using SCL and SDA pins from different GPIO ports—for example, SCL from port PA and SDA from port PC. Is it acceptable to assign I2C ...
Hi !I am evaluating the risks associated with STM32F3, where I am speculating a case where the voltage drops in VDD for few microseconds. For an example, let us assume the voltage drops from 3.3V to 3.0V for few microseconds. This occurs every x ms (...
Hello ST experts,I have bought a STM32H750IBT microcontroller. Could you please let me know how I can find whether it is V revision or Y revision device?
Recently i bought this STM32F103C8T6 Board along with ST Link V2 I was trying to upload a HEX(60KB) file using STlink software but i noticed something wierd, memory size in both pics is showing 256KB but this device only comes with 64KB flash memory ...
Hi all,I am Struggling with STM32L432 CAN Bus communication from one STM32L432 to another STM32L432 using MCP2551.* I have checked loopback works.*I am using HSE Clock (After soldering SB17) - * I have also tried putting Oscilloscope at TX pins betw...
Hello,I’m currently working with I3C communication using STM32H7S3L8 and encountered a case where the controller (master) sends a read request, but the target either does not respond or sends no data. This section explains: How to distinguish a NACK ...
