Posted on August 01, 2016 at 19:03Hi,I am trying to program the OTP flash on a L4 via STLink V2, however, it gives the error: The elf loader file is not accessible.Writing 0x00000006 at 0x1FFF73F8...Error!I have tried using the CLI with the command ...
after the firmware upgrade(V2.J31.S7) my st-linkv2's gives usb connection errors ST-LINK error (DEV_USB_COMM_ERR) sometimes stm32cubeProgrammer does not see the programmer at all and both cases it does not see the microcontroller. i dont have any iss...
Posted on April 24, 2018 at 09:24Hello there is an missing explanation on user manual at page 12. Because there is no ground (GND) connection on pin 4 of the CN3. We have also STLink v2. We connected same pins to STLink v2 ISOL for SWD (we are using...
Posted on April 12, 2017 at 12:03Hi,we are using the CLI of the st-link utility to flash some STM32-controller in the production. Now I had to install a newer version (CLI v2.0.0 vs. CLI v3.0.0) to support the STM32F413.With this new version the be...
Posted on July 13, 2018 at 10:13Hi, i'm using STM32F407VG discovery board for a project.I have this problem, when i power up the board it outputs some random signals for 3 to 4 seconds before it starts executing my code.I did the ST-link update and ...
Posted on July 12, 2018 at 22:27I am trying to connect to my running application and read some variable values from RAM. I am using ST-Link CLI with HOTPLUG option, but the core gets Halted after connect and the RAM content is invalid. The programme...
Posted on July 09, 2018 at 13:52Hello guys!I'm trying to build an automation that involves flashing and reseting an STM32F407 MCU.I'm using ST-LINK CLI V3.2.0.0 in order to do so.My problem is, that when I try to reset the MCU using -Rst -Run the ST...
Posted on June 28, 2018 at 12:48Hello there,Does anyone uses the external loader of the ST-Link tool for the STM32L073xx micro-controller (MC)?What we would like to do:We have a board based on the STM32L073rz. On this board, we have an EEPROM conn...
Posted on June 25, 2018 at 13:31The stm32f4 discovery board I am using has read out protection enabled, and I can't deactivate it.First of all, it is impossible for me to set read out protection, as the attached screenshot shows, the apply button fo...
Posted on June 26, 2018 at 09:00In STM32F411 Discovery board, The STlink was not able to program the on board STM32f411, so i have usedSTLink /v2 external module to load the program into MCU. I have also applied the target voltage 3.3V to the board ...
