Firmware Upgrade Validation Procedure

TFTP Server Setup

STEP 1:

Add require SSID and PSK in /etc/wpa_supplicant.conf file in below format

network={

ssid="username"

psk="password"

Install xinetd and tftpd-hpa application in your local PC to setup tftp server by using below command

Code Block
languagebash
titleTFTP Server Installation Step
sudo apt-get install xinetd
sudo apt-get install tftpd-hpa


STEP 2:

Create checksum file for your upgrading image.}

Code Block
languagebash
titleConsole output
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1

network={
ssid="RDK"
psk="Comcast1"
}

STEP 2:

Reboot the Target

After Reboot don't do step 1 and 2.

Note : Step 1 & 2 is only applicable for fresh target boot-up with new image.

STEP 3:

Modify needed resolution in rms configuration file

Supported Resolution:

SD:

Width - 640 , Height - 480

Width - 720 , Height - 576

HD:

Width - 1280 , Height - 720

FULL HD  :

...

Modify resolution in below configuration file

cd /usr/local/rms/bin

vi rms.conf

Code Block
languagebash
titleConsole output
RRSIP=18.224.54.11
RRSPORT=81
ROOMID=rpi0
RRSSSL=0
WIDTH=1280
HEIGHT=72

After resolution modification need to reboot the target.

Note: This step is not necessary,it is depends on your resolution validation.

STEP 4:

WiFi connection is must needed for RMS validation.

Check WiFi connection by using below command.

ifconfig

md5sum checksum creation
md5sum "<imagefile_name>.rootfs.rpi-sdimg" > imagefile_name.txt

for Ex:
upgrading image file is rdk-generic-camera-image_default_20200329074421.rootfs.rpi-sdimg
md5sum "rdk-generic-camera-image_default_20200329074421.rootfs.rpi-sdimg" > rdk-generic-camera-image_default_20200329074421.txt


STEP 3:

Create new folder for example "tfphome" in your PC home direcotry to maintain checksum file and upgrading image file.

Keep upgrading image file and checksum file in your created folder for example "tftphome"

for Ex:

Keep rdk-generic-camera-image_default_20200329074421.rootfs.rpi-sdimg and rdk-generic-camera-image_default_20200329074421.txt files in your tftphome folder.


STEP 4:

Check tftp file is there or not in /etc/xinetd.d/ directory. if it is not there then create tftp file under this /etc/xinetd.d/ direcotry and add below content.

vi /etc/xinetd.d/tftp

Code Block
languagebash
