Posted on March 05, 2014 at 12:53Hi,Is there a way to downgrade the revision of the ST-Link/V2 firmware, let's say from V2.J19.S0 to V2.J17.S0 on the Discovery kit?Regards,Fahmi #st-link/v2-firmware #st-link-utility-3.0.0-v2.j17.s0
Posted on November 22, 2015 at 03:23I prepared the circuit in the attached image and planned to remove the ST-Link part of the board to finish my project. Before doing this (because I messed it up last time) I checked that I could externally power ...
Posted on May 14, 2014 at 17:57I have both an STM32 Nucleo and STM32F429I-DISCO discovery board. On the Nucleo the ST-LINK is version 2-1 which creates a virtual COM port on Windows that is connected to USART1 of the target MCU. This is very handy f...
Posted on November 06, 2015 at 06:41I'm using Keil uvision(on windows 7 as well as windows 8.1) to implement ADC & DAC functions on STM32F4-Discovery board. After my last trial, ''ST-Link Connection Error'' occurred and ever since, I need to do a ''...
Posted on October 06, 2015 at 13:32Hello all,I'm using two Nucleo-F401RE boards which do some cross communication and timing monitoring. Initally I used boards with revision C-01 and HSI as clock source. This worked fine when doing individual clock-...
Posted on October 17, 2015 at 18:49Hi Community, I was using a NetDuino 2 Board which is just an STM32F205. Since I couldn't get the USB HID device to work correctly I thought I would take a shot at making my own firmware for the board. I created a ...
Posted on October 06, 2015 at 06:12I have a new STM32F401 discovery board, but the on-board ST-LINK stops responding only after a few programming. It shows ''internal command error''. I have to press the reset button when I want to program/debug the...
Posted on September 21, 2015 at 10:45Is the ST-Link/V2 able to supply power to the target?The UM1075 User Manual is not at all clear on this.AIUI, 'VAPP' (pins 1 & 2 on the 20-pin JTAG/SWD connector) provides the supply voltage from the target; ie, ...
Posted on September 16, 2015 at 00:04Hi.I have just upgraded one of our boards from using the STM32F030C8T6 to the more or less pin-compatible STM32F030CCT6.The only change that had to be made was to supply the one extra power supply rail to pin 35 ...
