Platform SDK Upgrade from Version < 1.19¶

This 2-step process is required when upgrading from a Platform SDK version earlier than 1.19. It prepares each SoC with the correct bootloader firmware before completing the upgrade.

Note

For fresh installs or upgrades from 1.19 or later, use the standard installation procedure instead.

Step 1: Install SDK without SBL Upgrade¶

Install the SDK while skipping the Secondary Bootloader (SBL) upgrade. This updates the runtime and drivers without touching the bootloader firmware.

sudo ./install.sh --no_auto_upgrade_sbl --ecc enable --setup_mdp all

Step 2: Update Firmware on Each SoC¶

Once the SDK is installed, update the bootloader firmware on each device individually before the new SBL takes effect.

# Wait for devices to initialize
sleep 10

# List all QIDs in the system
sudo /opt/qti-aic/tools/qaic-util -q | grep -e QID

# Update each QID (repeat for all QIDs)
sudo /opt/qti-aic/tools/qaic-firmware-updater -d <QID> -f

# Reset cards
sudo /opt/qti-aic/tools/qaic-util -s

Note

For flashless boot cards, use:

sudo ./install.sh --ecc enable
# For ESXi VMs:
sudo ./install.sh --datapath_polling --ecc enable

After completing both steps, continue to Post-Installation.
