PS225 User Guide Quick Start Guide

NOTE: Ensure that there is connectivity with the host (follow the PS225 Quick Start Guide in Table 1 for additional details).

a. On the host, download the Ubuntu image with the following commands:

byang@byang-PowerEdge-2950:~$ wget http://cloud-images.ubuntu.com/releases/16.04/release/ubuntu-

16.04-server-cloudimg-arm64-root.tar.xz

b. Ensure connectivity between host and PS225 with the following commands (see the PS225 Quick Start Guide in

Table 1):

byang@byang-PowerEdge-2950:~$ sudo insmod ~/temp/bnxt_en-1.8.29/bnxt_en.ko

byang@byang-PowerEdge-2950:~$ sudo ifconfig enp8s0f0 192.168.1.20 up ; ping 192.168.1.10

Pinging 192.168.1.10 with 32 bytes of data:

Reply from 192.168.1.10: bytes=32 time=1ms TTL=128

Ping statistics for 192.168.1.10:

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:

Minimum = 1ms, Maximum = 1ms, Average = 1ms

c. On the PS225, scp the Ubuntu image with the following command:

root@bcm958802a8048c:~# scp byang@192.168.1.20:~/ubuntu-16.04-server-cloudimg-arm64-root.tar.xz.

d. Set the correct date with the following commands so that tar accepts the future time.

root@bcm958802a8048c:~# date -s "14 MAR 2018 20:00:00"

root@bcm958802a8048c:~# cd /mnt/ubuntu

root@bcm958802a8048c:/mnt/ubuntu# tar --numeric-owner -xf /mnt/ubuntu/ubuntu-16.04-server-

cloudimg-arm64-root.tar.xz

8. The new rootfs is extracted in the specified partition (in the example above /dev/mmcblk0p5). chroot to the device

to set up several items before the kernel boots that rootfs for the first time. This step is important, otherwise the Ubuntu

OS does not boot properly. See the following commands:

a. Copy the bnxt* modules from the yocto filesystem to the ubuntu rootfs with the following command:

root@bcm958802a8048c:/mnt/ubuntu# cp -r /lib/modules/$(uname -r) lib/modules

b. Switch to Ubuntu's filesystem through chroot with the following command:

root@bcm958802a8048c:/mnt/ubuntu# chroot /mnt/ubuntu

c. Remove cloud init from this prebuilt image (since it interferes with normal boot) with the following command:

\u@\h:\w$ dpkg --purge cloud-init

d. Add getty for ttyS0 with the following commands:

\u@\h:\w$ cp /etc/init/ttyAMA0.conf /etc/init/ttyS0.conf
