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...
My company just purchased 10x new STLINKS in WINSOURCE.We are having trouble using them with newer versions of STCubeProgrammer(v.2.10.0),they work fine with the old STlinkUtility.I am also unable to upgrade the Fake STlink: The BOX seems legit: The...
I have a NUCLEO-L452RE-P, on the box and on the user manual (UM2206) it show that PD2 is on CN5.4 and PC5 is on CN6.6. But the STM32L452RET6P doesn't have those pins (PD2 and PC5). To what are connected CN5.4 and CN6.6 ?
