OTA lets the dashboard push new firmware to a device. It’s off by default — enable it in Kconfig and use an OTA-capable partition table.

​
1. Enable in sdkconfig.defaults

CONFIG_HYPERWISOR_ENABLE_OTA=y
CONFIG_PARTITION_TABLE_CUSTOM=y
CONFIG_PARTITION_TABLE_CUSTOM_FILENAME="partitions_16mb_ota.csv"

​
2. Add a partition table

Copy the matching CSV from the component’s partitions/ folder into your project root. Variants are bundled for common flash sizes:
Flash sizeFile
4 MBpartitions_4mb_ota.csv
8 MBpartitions_8mb_ota.csv
16 MBpartitions_16mb_ota.csv

​
3. Build and flash

After building and flashing once, the dashboard’s Push Update button can deliver new firmware over the air via the OTA_UPDATE cloud command.

​
Security

Without Secure Boot V2, OTA is unauthenticated — anyone who can reach the device’s realtime session can push arbitrary firmware. Enable Secure Boot V2 + Flash Encryption for production deployments.
