A xv6 port on D1.
Currently I run on Nezha.
Unbuntu:
- USB-UART driver:
sudo apt install libusb-1.0-0-dev - build xfel
- COM GUI: [cutecom]:
sudo apt install cutecom
lsusb
Bus 001 Device 004: ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC Bus 001 Device 005: ID 1f3a:efe8 Allwinner Technology sunxi SoC OTG connector in FEL/flashing mode
sudo adduser <user> dialout
sudo xfel version
AWUSBFEX ID=0x00185900(D1/F133) dflag=0x44 dlength=0x08 scratchpad=0x00045000
npm install --global xpm@latest
xpm install
./dev build
Now open a Serial session in Cutecom GUI, select serial device "/dev/ttyUSB0", baud rate is 115200bps
Run ./dev start
See UTART output in Cutecom.
WSL:
- build xfel
- USB-UART driver:
sudo apt-get install libusb-1.0-0-dev
Windows:
- xfel (we don't use xfel in Windows actually)
- Driver for FTDI USB-UART converter
- FEL Driver for Allwinner Technology sunxi SoC OTG, this one is for FEL mode
Both: usbipd

In Windows:
usbipd wsl list
# find the bus_id of vid 1f3a:efe8
usbipd wsl -a -b 1-8
Now open a Serial session in Mobxterm, select serial device "COM3 (USB Serial Port (COM3))", baud rate is 115200bps
In WSL Ubuntu:
lsusb
# an additional usb device
# Bus 001 Device 004: ID 1f3a:efe8 Allwinner Technology sunxi SoC OTG connector in FEL/flashing mode
npm install --global xpm@latest
xpm install
./dev build
./dev start
check the serial port output in the above Mobxterm session tab.
