Hello We brought new St-Link/V2, Now I tested with STM32CubeProgrammer , In this we unable to read serial number of this St Link (some time it shows '@' symbol) . please check the attached the .png file Same issue we found in working ST-Link pre...
i got schematics for a board that i should work on. it's stm32 L0 based. they did put SWO also on CS of a SPI EEPROM. I'm not a hardware designer / debug protocol specialist but i could imagine debug scenarios where toggling the chip select of an EEP...
Hello,I have been stuck trying to connect my ST-Link V2 to my custom PCB. I am confident that each of the connections made on the schematic are correct and that the solder joints are ok. I have tested everything with a multimeter. I have tried updati...
I have a STLINK-V3SET that no longer can be connected to by any IDE/Debuggers. This includes STMCube, ST-Link Utility, and IAR Workbench. When I plug it in it shows up in the device manager as a COM port labeled "STMicroelectronics STLink Virtual COM...
I have been struggling to get USB CDC device to work for the Nucleo without any additional USB peripherals. USB CDC works perfectly fine when I use the DISCO-board connected through the USB-micro, with the same MCU as the NUCLEO. I have connected a c...
Hi everbody. I've developed a project for STM32H7A3IIK6 [BGA package] and i've mounted the bypass capacitor on the same side of the MCU [not on the opposite side as suggested by STM Application Note] because of problems related to my production proce...
We connect STLINK/V2 to STM32G071 with 3 wires : SWDIO, SWCLK and GND. It always failed to connect. However, we can connect by using JLINK. We notice that STM32G071 combines the boot0 with SWCLK. Does this make STLINK/V2 failed to connect ? How can w...
Hi All,I am going to use STM32L471xx. So I am wondering what is the Eval board for that family. I searched for one and couldn't find any eval boards.Note: I only found STM32L476G-EVAL for STM32L476ZGT3, but we are interested in the STM32L471xx family...
Nucleo STM32F411RE, two VL53L0X, a DRV8833 driver and 2 6v motors. Power is from 2 x 3.7v18650 batteries (7.4v) on the VIN power input.5v regulator powers the 2 sensors.The batteries power the regulator, the VIN of the board and the motor driver.I do...
