Hi, I need to control Stlink form python code.1) On some PC I am not able to connect with STLink to my MCU - I tried STM32CubeProg and ST-Link utility. The Error is UR connection mode is defined with the HWrst reset mode.But why on the same PC the S...
Hello Team,We are planning to use the MCU STM32L496QGI6 for one of our new projects.The MCU will be powered from a 1.8V source (since all external peripherals are working in 1.8V only).One of the SPI slaves is working in 3.3V, so we are planning to u...
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...
