6.1 Firmware updates

nRF7002 supports device firmware updates for bug fixes, security fixes, or additional functionality.

The updates are performed by patching the firmware. The firmware patches are downloaded from the

host to the device for patching the ROM-based firmware. The patch download is fully automatic and

handled by the Wi-Fi driver software running on the host device.

Patches are downloaded to the nRF7002 device when powering up the device. Patches are downloaded

into the patch memory, which is retained during sleep. The maximum patch size is 128 KB.

Patches are linked to a Wi-Fi driver version and delivered as a byte array included in the Wi-Fi driver.
