We can backup the nand flash partitions on PC via the USB otg port with rkflashtool.

   sudo apt-get install libusb-1.0-0-dev
   git clone https://github.com/linux-rockchip/rkflashtool
   make

Put your device into Loader Mode and run the following command

   sudo ./rkflashtool p > parameter                   #fetch parameters

open parameter file and check out all the partitions. It's like this mtdparts=rk29xxnand:0x00008000@0x00002000(boot),-@0x0000A000(linuxroot)

   rkflashtool r boot > boot.img
   rkflashtool r linuxroot > linuxroot.ext4 # This will take a long time

Now you have the parameter and the image for all partitions.
