It is also worth checking here are you connecting to both USB ports on the board? That configuration will expose a CDC/ACM device on the non-debug USB port on the board.
It is also worth noting that they made a slight change to the design around the debugger in that version so you can also get the UART via ST-Link port and (I believe) be able to just use that with the NSH (non usb) configuration to get the console. --Brennan On Wed, Dec 2, 2020 at 9:41 AM Alan Carvalho de Assis <acas...@gmail.com> wrote: > > Hi Thiha, > > I don't know what you mean "does not work". > > It is like someone calling the Help Desk and saying: "My computer > doesn't work" Hehehe > > You need to describe what exactly is not working based on the steps > you are doing. > > After flashing the firmware and resetting the board, does the dmesg > command on Linux shows that a CDC/ACM ttyUSB0 device was detected? > > Just a dump question: > > Did you hit <ENTER> three times after opening /dev/ttyUSB0 on minicom? > > BR, > > Alan > > On 12/2/20, Thiha Kyaw <thiha....@gmail.com> wrote: > > Dear Nuttx, > > > > USBNSH console does not work in stm32F407G-disc1 Board. > > > > stm32F407G-disc1 is upgraded version of stm32f4discovery board. > > > > I only see the serial port from STLINK. > > > > How can I get nuttx serial port from USB? > > > > I use Ubuntu 18.04 > > > > Thanks. > > > > -- > > Yours Sincerely, > > Thiha Kyaw > >
