Posted on June 21, 2017 at 18:03I have a custom board with STM32L051 on it. I am using an example from ST (I-Cube_lrwan). For some reason, once I load the firmware I cannot access the MCU anymore using ST-Link Utility and ST-Link/V2. It always throw...
Posted on June 25, 2017 at 14:00I am designing a PCB which uses the STM32F446 MCU. I have the first revision done and working. But I am wondering if all the pull-up and -down resistors on the board can be excluded and use the internals instead?The b...
Posted on June 09, 2017 at 12:57Hi all,I designed a electronic board with two microcontrollers (STM32F401 and STM32F407), for my project.At the moment, I am using an external ST-link and the SWD to program them in the prototype. Every MCU has a SWD ...
Posted on June 01, 2017 at 08:58Hi,I want to use the ST-Link Utility command-line tool for production: flash a BootLoader and the current applicationdo production testsif all is OK - flash the production data (serial-number, timestamp, etc., ~50 by...
Posted on June 08, 2017 at 17:33hi, fellows!I have some questions about ST-Link, especially those on Nucleo boards.First, I often use the on board st-link link to debug/program some other custom boards, it works fine.But someday, I'd noticed that t...
Posted on May 29, 2017 at 14:01hi,I'm working on a project, on a stm32F101.The product is a proprietary boot-loader and application (which can be updated later on, via the BL).I'll need to hold some production-data, serial-number, etc, less than 256...
Posted on May 30, 2017 at 09:42 Hello all, I am trying to use an STM32F4103T6U7A in an application where an USB CDC stack would be used. I am using the STM32 Workbench, an original STLink V2. If I generate my project with Disabled USB cl...
Posted on May 19, 2017 at 17:25Hi!When I flash a .hex or .bin file with a ST-LINK V2 device on my STM32F4 microcontroller (with ST-LINK utility), the program only works if both the ST-LINK V2 and my MCU board stay connected to the computer (through ...
Posted on May 18, 2017 at 11:26Hi everyone, I'm struggling with a flashing problem for ST MCU (STM32F070CB). I'm using the STM32 ST-LINK CLI v3.0.0.0 from http://www.st.com/content/st_com/en/products/embedded-software/development-tool-software/stsw-...
Posted on May 12, 2017 at 11:02I've noticed this behaviour in Atollic TrueStudio 7.0.1 and 7.1.2, using the ST-Link V2 debugger (several variants, including the regular ST-Link V2 and the ISOL version). When I place a breakpoint in the code, the exe...
