STM32 MCUs Boards and hardware tools

Help with OpenOCD and STM32L082

I'm using JetBrains CLion as a development environment, with OpenOCD and GDB as the flash/debug toolchain.I have a custom board with STM32L082CZ, similar to the B-LR072-LRWAN1 board.I have previously been using STM32CubeIDE and its integrated flash/d...

Proper option for programming/debugging connector

HelloI just got my ST-LinkV3 programmer and noticed there's many other ways to connect and program these STM32 series.I am asking for common chips like L152, F4XX, G030 and alike, for hobby but also possible professional designs.ARM website itself pr...

I want to remotely reset and start a STM32H753 eval board.The board is connected to a PC through STLink and on this PC I run STLink-gdb-server in persistent mode.ST-LINK_gdbserver.exe -d -e -v -p 61234 -a 400000000 -b 200 -i *** -cp "***"On my develo...

STLINK-V3MINI programmer alternatives

Hello,I have my STLINK-V3MINI just broken. I could not find any more on web. I have also an ST Link V2 available. May I use it for my STM32L4R9ZIT6? Any tools available from JTAG20 to STDC14?Eventually, do you suggests any alternative programmer?Than...

NRST pin characteristics of STM32F2xxx

STM32F20x datasheet talkes about TNRST_OUT, but Figure 40 shows NRST pin as input. Which is right?In view of point NRST can be behaved as OD output, then it will expand the external reset pulse is expanded by 20us?e.g.In other words, external periphe...

STM32F103 chips from different origins cannot program

We purchased the STM32F103 MCU chip in the China, and it can be seen from the silk screen that there are two origins, one is Malaysia and the other is Taiwan. For the same HEX program, MCUs made in Malaysia can be programmed and erased normally throu...

Hi everyone, when I try to debug my STM32L452RET6P microcontroller, it's showing an 'Error in initializing ST-Link device. Reason: No Target Found on Target'. How can I solve this problem? Note: I have already tried full erase chip but it didn't work.
