I just can't enter DFU mode anymore (and flash to newer version of Betaflight).Īfter I use "BL" CLI command in Betaflight or use the physical bootloader button on FC, it doesn't show "DFU" in port selection in BF configurator anymore. Same problem here with my CLRacing F4 FC. This is a nightmare and I have never seen anything that compares to that in a life long IT career! If they go on like that they have to re-learn what it means to work for their living and not only crooking hobby enthusiast for their money by YouTube hypes.

And there are hundreds of similar threads and posts throughout the forum world ith th sam contends I cannot get rid of the impression that these people have forgotten what serious development work means! Tons of jerk and nerd features but no will to solve any basic issues lasting for quite a long time despite that they have been informed by numerous people about these facts for quite a while now. I am completely fed up with that crap, that costed me thousands of $ and i'll check out KISS or abandon the hobby.

STM32 VIRTUAL COMPORT IN FS MODE DRIVER DRIVER

No Zadig works and no ImpulseRC Driver Fixer! Nothing

STM32 VIRTUAL COMPORT IN FS MODE DRIVER MANUAL

No re-installing nor manual driver fixing, nor any de- and re-installation solved the problem nor did any hack. I tried it on several samples of each type. However when I try to connect I get a device busy Im using an STM32F407ZGT and MAC.Since the latest updates of Windows - no matter whether W7 or W10 - there is no way to get into the bootloaders of any Betaflight or Butterflight based FC (JB4, Heliospring, CLRacing F4 or Betaflight F4). I looked inside the sources and I can say my board did not try to connect to Windows host. You can get the data pointer and data length from arguments of this function.

STM32 VIRTUAL COMPORT IN FS MODE DRIVER DRIVERS

I dont even have it under com ports, just unknown USB device.Īfter that, if the Windows Virtual com-port drivers are correct you should change the electrical connection between the board and PC. In file usbdcdc.c, change the define CDCDATAHSMAXPACKETSIZE from 512 to 256.īut let me advice you to grow the next values in to 64: USER CODE BEGIN PRIVATEDEFINES Define size for the receive and transmit buffer over CDC Its up to user to redefine andor remove those define define APPRXDATASIZE 64 define APPTXDATASIZE 64. In file usbdcdcif.c, change define USBHSMAXPACKETSIZE from 512 to 256. Generate the source code with no other changes needed to any USB settings. The COM port was not accessible with a terminal appliaction (PUTTY).

STM32 VIRTUAL COMPORT IN FS MODE DRIVER SERIAL

In order to receive the data we can use any serial port monitor utility.Īfter installing the STM virtual COM port driver, Windows Device Manager showed a STMicroelectronics Virtual COM Port, but with a yellow warning mark.

Stm32 Virtual Comport Serial Port Monitor In this project we have no need to change any of them, so its time to generate the new project In contrast to previous posts lets compile the project without any changes.Īfter that lets program the MCU and connect the board to the PC.Īll necessary functions for data exchange via USB Virtual COM Port are located in the file usbdcdcif.c.įor the delay implementation HALDelay() function can be used.ĭelay value in milliseconds should be passed into this function. The final clock settings for this project are shown in the picture.Ī new configuration window will be shown, where different USB properties, such as VID and PID, can be set. This can be done by setting the mode of the USBOTGFS module at the Pinout tab. This process is quite clear, because weve done it a lot of times in previous posts. Some time ago we worked with the USB Mass Storage mode please dont miss this article.
