I am currently working on a HIL Setup. I want to flash my Target Software on a STM F3 via SWD. Only the SWD Pins pins are free, all other Pins are already used and can't be used for flashing the device. I have a STM H7 on the simulator of the HIL. I ...
Hi guys,I'm working in a project with a STM32L412RBT6. Due to a misunderstanding, the company i'm working with, bought a big stock of STM32L412RBT6P. I just discovered the meaning of that final "P" in the code and i'm trying to figure out how big the...
I have recently purchase ST-LINK V3 MODSI am trying to connect it using SWD protocol using STM32CUBE PROGRAMMER software but it gives error DEV_TARGET_CMD_ERR if i use STLINK V2 then it works fine.how can i solve this?is there any connection problem?...
Hello, I designed and assembled a simple circuit around the STM32G0B1KET and after connecting my ST-link it does not seem to "boot". My circuit looks like this: Additionally, there is a red LED through a 330Ohm resistor connected to 3.3vI am poweri...
Hi everyone, I need to power my F401RE with a 3.3V external power source. I read in the datasheet I need to connect the power source to the CN7 pin 12 or CN7 pin 16. Where do I connect GND signal apart from 3.3V signal?Also, from what I understood, I...
Hi all,I've tried every example I can find to send data to a terminal using UART on my Nucleo 144. Every time the code builds fine but there is never anything on the terminal, and the code doesn't get stuck anywhere it runs fine.
A PC app sends a reset command via USB. In the main app I use HAL_NVIC_SystemReset() to reset the board. If I use HAL_NVIC_SystemReset, windows loses USB com port and does not re-enumerate port unless I plug out and plug in USB cable. The PC app talk...
