Posted on August 28, 2014 at 12:08Hi, I was uploading programs to Standard STM32F051R8 development board. While trying to upload the code, suddenly I have started getting an error message ''ST link No MCU Device found''. After I click on OK I got a...
Posted on November 07, 2012 at 20:24I'm trying to verify that I can program an STM32L on the Discovery board using an external ST-Link V2 debugger. As far as I know, I only need the SWDIO and SWCLK pins (7 and 9 respectively) and ground. The SWDIO l...
Posted on July 29, 2014 at 01:49Hi i'm new using ARM architecture i bought the STM32F4 Discovery Evaluation Card, it stop working after trying to load my first program, the demostration code no longer runs, the only thing is doing when i plug the US...
Posted on July 24, 2014 at 12:08 Hi, I'm trying to program http://andybrown.me.uk/wk/wp-content/images//awreflow/schematic.pdf with a stm32f0308-disco st-link but it only works if I power the board with the 3v from the disco board if I po...
Posted on June 24, 2014 at 08:36 I am downloading file to chip with stlink/V2, the command line tool works fine for me.However, if the chip is on protect statue, the command line tool failed with below log:>>> Erasing PROGRAM MEMORYThe device is pr...
Posted on June 12, 2014 at 06:50Hi,I am planning to use STM32 series microcontroller (http://www.st.com/web/catalog/mmc/FM141/SC1169/SS1031/LN1565/PF164476) in my project. Wondering if anyone has footprint library for LQFP48 package. I am designing ...
Posted on May 10, 2014 at 01:24I have no problem using Utility v3.1.0 and firmware V2.J17.S0 with a Discovery-F3. I'm having a problem with v3.3.0 (the latest) with firmware V2.J19.S0. Most everything works except that the MCU Core Panel dialog fail...
Posted on April 19, 2014 at 16:52Hi there, I've designed a board on stm32f407zgt6 earlier and succeeded to connect my board with st link. All SWD connections were directly taken out from controller with no external pull-ups or pull-downs. Now again ...
Posted on March 24, 2014 at 02:43Hi all, I am using the STM32's ITM to output log messages to my PC via SWO. However, I have run into issues with losing characters (as has been noted elsewhere; e.g., /5056d518). Apparently ST-LINK fw V2.J19.S0 imp...
Posted on June 18, 2012 at 20:59Hi to all STM guys here. Thank for all the great eval boards you do.We just had a sparks-generating discussion on a forum from where camse an idea that we miss an interaction with PC capability on the discovery boards...
