Introduction

The Firmware upgrade will upgrade higher or lower version of the current image in RPI target with the help of Xconf server and Local TFTP server by using Rdk Services

System Services-Plugin via  updateFirmware curl command  .


Yocto Build Steps

Refer below link to build rdkv image

Yocto Build Instructions - RPi - RDK Video - 2020 - M12#196872666


Image Flash Procedure

Image Flash step

$ sudo dd if="Image Name" of="Device Name" bs=4M
 
Example:
sudo dd if=rdk-generic-hybrid-wpe-image_default_20201221142654.rootfs.rpi-sdimg of=/dev/sdb bs=4M


Firmware Upgrade Validation Procedure

TFTP Server Setup

STEP 1:

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

sudo apt-get install xinetd
sudo apt-get install tftpd-hpa


STEP 2:

Create checksum file for your upgrading image.
md5sum checksum creation

md5sum "<imagefile_name>.rootfs.rpi-sdimg" > imagefile_name.txt
 
for Ex:
upgrading image file is rdk-generic-hybrid-wpe-image_default_20201221142654.rootfs.rpi-sdimg
md5sum "rdk-generic-hybrid-wpe-image_default_20201221142654.rootfs.rpi-sdimg" > rdk-generic-hybrid-wpe-image_default_20201221142654.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 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
TFTP File Content

service tftp
{
protocol        = udp
port            = 69
socket_type     = dgram
wait            = yes
user            = nobody
server          = /usr/sbin/in.tftpd
server_args     = -c -v -s /home/xyz/tftphome ( Give upgrading file and checksum file maintained directory )
disable         = no
}


STEP 5:

Verify /etc/default/tftpd-hpa file content

vi /etc/default/tftpd-hpa
tftp-hpa File Content

# /etc/default/tftpd-hpa
 
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/home/xyz/tftphome" ( Give upgrading file and checksum file maintained directory )
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="--secure"


STEP 6:

Start tftp server and xinetd server

sudo service tftpd-hpa restart
sudo /etc/init.d/xinetd restart

XCONF Server Setup

Create Firmware Rule

STEP 1:

Select Firmware Rule option within common list to enter Firmware Rule page.

After entered Firmware Rule page press create button to add your device firmware Rule detail.


STEP 2:

After entered firmware Rule page you can see list of template.

Choose MAC_RULE in this list of Template to add your device MAC list in Firmware Configuration.


STEP 3:

After entered Firmware Rule page.If any estbmac if there under build condition then remove that estmac before add your device specific Firmware rules.


STEP 4:

Add your device specific eStbMac under build condition option.

Verify XConf server configuration

Verify that XConf Server configuration displays the Json response from the mentioned URL:

http://<Xconf Server IP:port no.>/xconf/swu/stb?eStbMac=<MAC address of Rpi board>

For Ex: http://35.155.171.121:9092/xconf/swu/stb?eStbMac=B8:27:EB:2E:72:2B



Activate the System Serivce Plugin in the  Controller UI

 http://<ip_address_pi_board>:9998

  For Example:http://192.168.1.2:9998





Provide the UpdateFirmware Curl command in the Rpi board

root@raspberrypi-rdk-hybrid:~# curl --data-binary '{"jsonrpc":"2.0","id":"3","method":"org.rdk.System.1.updateFirmware","params":{}}' -H 'cont
ent-type:text/plain;' http://localhost:9998/jsonrpc


RPI-Board

  1. Flash the RDKV image supported for Firmware upgrade feature in the Rpi and verify the 2 partitions(ex. mmcblk0p1, mmcblk0p2) present under dev folder (use command ls /dev)
  2. Verify System Service plugin is activated in controller UI as: http://<ip_address_pi_board>:9998
  3. Provide the updateFirmware curl command on the pi board ex: root@raspberrypi-rdk-hybrid:~# curl --data-binary '{"jsonrpc":"2.0","id":"3","method":"org.rdk.System.1.updateFirmware","params":{}}' -H 'content-type:text/plain;' http://localhost:9998/jsonrpc
  4. Device auto-reboots and verify there are 2 more additional partitions are created (ex. mmcblk0p3, mmcblk0p4).
  5. After the board gets auto-reboots for creation of 2 more additional partitions (ex. mmcblk0p3, mmcblk0p4).Again  activate the  System Service plugin  in controller UI as: http://<ip_address_pi_board>:9998
  6. Provide the updateFirmware curl command on the pi board ex: root@raspberrypi-rdk-hybrid:~# curl --data-binary '{"jsonrpc":"2.0","id":"3","method":"org.rdk.System.1.updateFirmware","params":{}}' -H 'content-type:text/plain;' http://localhost:9998/jsonrpc
  7. Open /etc/include.properties file and verify the CLOUDURL parameter where XConf Server URL is configured
  8. Verify the image version ( cat /version.txt) displays the flashed image version
  9. Open /opt/logs/swupdate.log to verify the communication from RPI board with XConf Server and the download status
  10. Verify the tftp download is happening by noticing the change of file size using below command: ls /extblock/tftpimage/imagedwnldls  -sh  (use this command frequently to verify the file size change)
  11. Once image download completed, the Rpi board will auto reboot and come up with downloaded image
  12.  Verify the version of booted image which shows the downloaded image version

Conclusion

Please find the summary on firmware upgrade explained above

  • Build the image RDK-V Image.
  • Ensure 8GB sd-card is available for flashing
  • Flash the build image to sd-card
  • Setup xconf server ready with rules and download location for RPI device
  • Place the upgrading image and checksum file in tftp server
  • Boot the flashed image
  • Activation of System Service plugin in controller UI before executing Curl command
  • Curl command need to be provide twice initiailly after the RPI board bootup ,curl command for the creation of 2 more additional partitions  (ex. mmcblk0p3, mmcblk0p4) in /dev folder.and again after the auto-reboot of the RPI board curl command for image download
