Radiolink AT9 AT9S firmware upgrade from Ubuntu - sevrugin/fx-61-inav GitHub Wiki

  1. Connect AT9S to computer via USB cable and switch on your AT9S $ lsusb | grep 0483:df12 if you see output like Bus 001 Device 065: ID 0483:df12 STMicroelectronics go next

  2. Install the dfu-util tools from github!

git clone git://git.code.sf.net/p/dfu-util/dfu-util dfu-util-dfu-util
cd dfu-util-dfu-util/
./autogen.sh
./configure
make

Next you can run $ sudo make install or use dfu-utils from the src directory. I prefer to use a local copy $ cd src

  1. Show list of DFU devices $ sudo ./dfu-util --list you should see next output
Found DFU: [0483:df12] ver=0200, devnum=65, cfg=1, intf=0, path="1-4", alt=1, name="@SPI Flash : M25P64/0x00000000/128*64Kg", serial="56FD636E3637"
Found DFU: [0483:df12] ver=0200, devnum=65, cfg=1, intf=0, path="1-4", alt=0, name="@Internal Flash  /0x08000000/12*001Ka,500*001Kg", serial="56FD636E3637"

  1. Now you can download a firmware from http://www.radiolink.com.cn/doce/at9upgrade.html

  2. Now we are able to download the new firmware sudo ./dfu-util -a 0 -D ../../AT9\(AT9S\)_RadioLink_DFU_V1_7_8\(AT12S\)_a36f.dfu success output should be like this
