SD card partition #

In order to boot the CaaS Switch, you are supposed to have a micro SD card with >32GiB storage. Then use:

sudo apt-get install gparted
sudo gparted

Parition it into two partition below

• BOOT: store boot files from petalinux

  Free space preceding (MiB): 4

  New size (MiB): 500

  File system: fat32

  Label: BOOT

• ROOTFS: store debian system rootfs

  Free space preceding (MiB): 0

  Free space following (MiB): 0

  File system: ext4

  Label: ROOTFS

Copy files into SD card #

Mound SD card:

sudo mount /dev/sda1 /media/alinx/BOOT/
sudo mount /dev/sda2 /media/alinx/ROOTFS/

Remove original files:

sudo rm -rf /media/alinx/BOOT/* /media/alinx/ROOTFS/*

Copy files:

sudo cp BOOT.BIN boot.scr image.ub /media/alinx/BOOT

sudo tar -zxvf rootfs.tar.gz -C /media/alinx/ROOTFS
sudo cp -r ~/init_os.sh /media/alinx/ROOTFS/home/root/init_os.sh 
sync
sudo chown root:root /media/alinx/ROOTFS
sudo chmod 755 /media/alinx/ROOTFS

Launch the switch #

1. Launch the Board #

Plug the SD card into FPGA board, turn the switch to SD card boot mode.

2. Initialize PS #

Plug in SD card, setup AX7021 board to boot on SD, power on.

Connect a PC to the UART port of the board. We recommend using MobaXterm to connect the serial. Set up the Speed to 115200, Flow Control to None.

The default username and password are as follows:

username: "root"
password: "root"

Execute the initilization script to set up the linux environment.

sh init_os.sh

You can freely configure the host name, IP address, and MAC address, etc with the script, and can modify the script if needed.

3. Connect to Internet #

Connect the PC’s network port to the device’s PS network port (ETH0).

Set up PC’s corresponding port to be in the same subnet with the device (i.e., 192.168.137.x).

Afterwards, you can connect to the device through ssh and copy any Software files needed.

4. Run the Software #
