HelloI have created a prototype board using STM32L476RE.Then I did "Target" > "Connect" in ST-LINK utility, but I got the error as shown in the picture.I do not know the cause and solution. I did a lot of research on this site and checked the followi...
I'm using a Nucleo-F746ZG with timer 2 as a quadrature encoder input. I'm feeding it quadrature signals from 2 GPIOs at 250Hz (each phase is 1mS).The CDR value is 0, so FDTS should be CLK_INT (36MHz for APB1). With both inputs' filter set to 8, the...
My team has built up a complex test setup with about 72 ECUs of which all have an ST Link V2 connected to update all the controllers automatically.With the help of an USB extension board they are all actively connected to the PC. The issue is now, th...
Hi all,I build a prototype board based on STM32G431KBT6 which need Virtual COM port and DFU firmware upload. In previous version of the prototype everything worked fine.Windows detected the board, I was able to send/receive commands over VCP and also...
Can desoldering and soldering to replace a capacitor which is part of an RC filter of an I/O pin cause that pin to develop an internal short to VCC? This problem has now happened on 14 PCBAs. Any insight would be gratly appreciated. Regardsik
Hello ,recently I upgraded to ST Link V3 and it works fine so far. Only one thing is annoying: I always get a double reset when uploading a new firmware from Cube IDE to my target. Console output is this:STMicroelectronics ST-LINK GDB server. Version...
Hi all:I have problems understanding the pull up/down situation with regards to 5V tolerance.I must admit that I have limited hardware knowledge, so please be gentle. I have searched and read a lot, but couldn't find a definitive answer yet.Say that ...
