Hellonewbie question As I know I have to implement pull-up and pull-down on SWDIO/SWDCLK pins and also enter the boot mode by pulling down/up the BOOT0 and BOOT1 pins.However I cannot exactly find all this information on datasheet and I am afraid I'm...
Hi all, I made a PCB board with STM32F407VGT6 (MCU) + STM32F103CBT6 (Debugger). I get the message ''Usb device not recognizable'' when I try to connect it to my computer via USB. I include the pics of my schematic. I followed the schematic of STM32F...
We use the schematic attached to convert a 230 VAC signal to the STM32 level (low cost product). Maximum input high level is about 3.9 V. In worst case 5.4 V. This should not be a problem for the FTf pin because specification is VDDIO+4V = 7.3 V.But ...
Hello Team,I am using System Workbench for coding of STM32f30xx series micro-controller.I m getting some error on regarding St-link match frequency , that is below:-Open On-Chip Debugger 0.10.0+dev-00021-g524e8c8 (2019-04-12-08:48)Licensed under GNU ...
I had a problem with STMF334R8, I loaded the same program on several boards with some STLINK V-2, via CubeIDE and then when I tried to conect the MCU's again to the computer i had an error: failed to initialize GDB server, and in the console it appea...
Hello,the STLink V3 are nice, capable boards and could be a nice playground if it would be possible to load own user programs via the bootloader. Are there any chances we get such a bootloader?Thanks
DISCO board for the new 'L4Pxx is out:https://www.st.com/en/evaluation-tools/stm32l4p5g-dk.html?icmp=tt14426_gl_****_mar2020#Remarks:yet another naming scheme, with -DK suffix - bad idea, DISCO was a good keyword to search these at the distributorsno...
Hello, Please correct if I am wrong. I have a nucleo-H743ZI2, with on board ST-Link debugger, which firmware has been update to V3 when plugged in.My goal is to use vscode IDE under linux, although creating the basic sources files using the STMcubeMX...
Hi, We have a product based on a STM32F412CGU6 MCU that is currently going through certification. Are there any known ESD issues or knwn reasons why the MCU would tend to latch up? We are seeing this behaviour and can't get to the bottom of it.Thanks...
Hello guysI am developing my own PCB where I want to use a STM32F767 MCU. I went ahead and figure out how to load binary and all but there is one thing that confuses meso from the schematics (datasheet) my MCU has more than one VDD and VSS (ground) I...
