Hello,We are building a board with with the STM32H753XI (TFBGA240+25 package).The assembly house for the PCB has notified us that the land pattern suggested in the datasheet is not complaint with IPC standards.I was unable to find any assembly recomm...
Usually with STM32 development boards I am able to see a virtual com port/serial port when I hook the board up to a computer via USB. This board, the F0308-DISCO, seems to have the TX/RX pair for UART communication between the target MCU and the ST-L...
Hello,I am trying to debug STM32F072 chip using ST-LINK on mb1076 Discovery board. STM32F072 is on custom board. It is powered from 3.3V except Vddio2 pin which is powered from 1.8V. I am able to program chip but when I try to debug it I get output R...
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...
