v18.3.0

Migration Guide

This document lists recommended and required changes for those migrating from the previous v18.2.0 firmware release to the new v18.3.0 firmware release.

• Going forward, and following the more standard semantic versioning of firmware, the filename of the combined firmware bundles will be of the form

  • fw_pack-<major>.<minor>.<patch>.fwbundle for final releases, and

  • fw_pack-<major>.<minor>.<patch>-rc<N>.fwbundle for release candidates (pre-releases)

• The Board Management Controller (BMC) on Blackhole cards has been renamed to Device Management Controller (DMC) in order to reduce possible confusion around the standard industry Baseboard Management Controller (BMC) which is part of the Intelligent Platform Management Interface (IPMI) specification. Any automation or scripts that refer to that “cpu cluster” (in Zephyr terminology) or application (app/bmc) should be adjusted accordingly.

• SMC FW telemetry removes board input current reporting, and replaces it with board input power. Any tools using the telemetry entry TAG_INPUT_CURRENT (39) should be updated to use TAG_INPUT_POWER (54)
