Getting the code

Note:

• The manifests repository is only available to RDK licensees.
• Opensource versions of the RDKB manifests are available from the rdkcmf/manifests repository rdkb-2025q2-kirkstone branch 

mkdir <workspace dir> 
cd <workspace dir>

# RPI 
repo init -u https://code.rdkcentral.com/r/rdkcmf/manifests -m rdkb-extsrc.xml -b rdkb-2025q2-kirkstone  

# BPI
repo init -u https://code.rdkcentral.com/r/rdkcmf/manifests -m rdkb-bpi-extsrc.xml -b rdkb-2025q2-kirkstone 

repo sync --no-clone-bundle --no-tags 

• The -m <manifest.xml> in the sequence above is important. If this is not specified, you will get an RDK-V tree by default.

  • For RPI builds use manifest: rdkb.xml

    repo init -u https://code.rdkcentral.com/r/rdkcmf/manifests -m rdkb-extsrc.xml -b rdkb-2025q2-kirkstone

• The -b rdkb-2025q2-kirkstone in the build sequence above specifies the branch to use.
• If you omit the -b rdkb-2025q2-kirkstone entirely, you will get the HEAD of each component

Testing

Sanity Testing

Automated RPI Sanity tests include:

• Services checks (OneWifi, ccsp processes)
• Network (WAN) connectivity 
• LAN client
• Wifi 2.4Ghz and 5Ghz hotspot testing.
• Login, menu navigation, parameter modification, e.g. Wifi SSID/password change and re-connection, changing admin password.

Manual Sanity Tests on RPI and BPI:

Known Issues

RDKBACCL-925 [TDK][AUTO][BPI][STABILITY]WiFi SSIDs are not broadcasting consistently in the long run - JIRA
RDKBACCL-965 [TDK][AUTO][BPI]6G capable clients unable to connected to BPI's 6G SSID - JIRA
 
 BPI Stability Issues:

1.BPI Wifi works fine in dev setups , but facing interference issues in QA setups where there may be more interference , resulting in  the TDK using the WiFi chamber for testing.

2.The fan unit have to kept as below to avoid overheating : 

     2.1  When we connect powersupply(white jack) to fan in the board, make sure jack is in proper contact with the pin. So we need to have the jack loosely connected with the pin (next to the fan you can find this pin that we are mentioning exactly top right position),

3. WiFi 6GHz is working with selected 6GHz capable STAs/clients like Apple iphone-16 pro as of now .

TDK & Automatics Testing

• TDK component, VRT, Cellular Manager and E2E tests were run against the release on both 32 bit and 64 bit builds
• TDK Manager used is TDK-B Release M138
• TDK-B Test Reports - rdkb-2025q2-kirkstone
