Dear Alan, I am switching back to normal nsh.
But I want to update a bit. I got ttyACM1 after building using the latest Nuttx. ttyACM0 is from STLINK. But nsh> shell doesn't appear. After hitting <Enter> a few times, the serial terminal is freezed. I have another board, STM32F429i-Disco. I didn't face this problem in F429i Board. stm32F407G-disc1 mini USB is at FS USB mode. TM32F429i-Disco's mini usb is at HS USB mode. I am not sure it could be the problem in usbnsh configuration. @Berennan, STLINK chip on stm32F407G-disc1 does not connect to any UART port. That's why STLINK port cannot use as a console as well. It is very special case. Thank you.
