Hi,I'm using STLink-V3 MiniE tu flash STM32L432CCU6 on custom board.The signal mapped are SWDIO & SWCLK. I connect T_VCC to 3V3.The connexions are correct has I was able to flash the target.I'm using STM32CubeProgrammer CLI, and control the target po...
HelloI have a custom designed circuit with bluenrg232 soc. There is a capacitor connected to Vin. Our problem is that the circuit works at the first start but when I turn off the power and wait for 10 or 20 seconds, I start it but now the circuit doe...
I had a working STM32G0316-DISCO board, but after programming the STM31G031 I cannot connect to the MCU anymore using ST-LINK. This is because I set pin 7 and 8 to a digital input whereas pin 7 and 8 are SWDIO and SWCLK respectively as well. This mes...
I'm trying to redesign the STM32F100RBT6B without ST-LINK. something I did from the STM32VLDISCOVERY schematic file. but the redesigned hardware was not working with STM32 ST-LINKER UTILITY. For your reference, I have attached a schematic file showi...
i have a blue EVAL board (STM32H735G-DK) that I think stopped working.There is a ST-com LED that starts green but changes to RED and stays that way. The driver shows up on COM 3 in device manger. The STM32CubeIDE that I use does this at time but this...
Hi fellow engineers, I have followed the steps in the manual and also in the 'Cellular X-CUBE-CELLULAR How To'. But after 30minutes still no connection. I uploaded the bin-file from --> ...\Projects\B-L462E-CELL1\Demonstrations\CellularIoT\..in short...
Hello.I'm having problems to program an STM32G474-NUCLEO Board with an external STLINK programmer. I'm using the STDC14 on-board connector and following the instructions given in the the board user manual. However, I get the error: "Error in initiali...
I have this board (revision C-04) with ST-LINK removed (PCB cut off), so the power 3V3 is supplied from CN7. It works fine, but the red power led (LD3) also works. LD3 is, I think, connected to the 5V net, and 5V to 3V3 regulator should not be workin...
