Connecting to this COM port using a terminal we can capture this string.Well, with modifying the setup to SD1 and an extra USB-USART(cp2102) attached, I got hello world with minicom.
Stlink Virtual Com Port Install System WorkbenchAnd, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4. Stlink Virtual Com Port Download Two ShortYou can get more information from the ac6-tools website and download two short videos (registration required) highlighting. Stlink Virtual Com Port Pdf Which ToldI think I have read some pdf which told that st-links vcp pins were not connected to any of the usarts of stm32f4. This virtual serial over stlink usb is possible as far as i know only with stlink v2.1. From it two lines, VCPRX and VCPTX come out and are connected to the. Before I answered to HugoARA telling to check if from the STLINK block. After that the device needs to be power cycled in order for VCOM to work. Connected devices with VCOM functionality will be listed under Ports (COM LPT). This leads to the Rx pin receiving the sent data meaning that VCOM is active and working. Use the letter U (01010101 in binary) to create a regular square-wave signal. The speed VCOM is operating at can also be determined with an oscilloscope, e.g. This daemon by default opens a connection to a CDC-ACM device (like a J-Link VCOM) as soon as the device has enumerated and starts sending AT commands over the device to the other side (usually a target MCU connected to J-Link). Depending on the target application, this may create problems because the target now receives unexpected data via VCOM. Fortunately, the ModemManager can be disabled for specific USB devices (filtered by VID and PID) via the Linux rules system (rules files). Bus 002 Device 005: ID 0bda:0411 Realtek Semiconductor Corp.
