Detailed Description

Decoded representation of the server manifest.

The manifest the server returns is JSON; ra8_ota decodes the relevant fields here. The struct is also used as the input to ra8_ota_download_to_inactive_bank and ra8_ota_verify_signature.

Invariant

image_size_bytes <= k_ra8_ota_max_image_bytes.

signature_len <= k_ra8_ota_signature_max_bytes.
