Why I did it Requirements from Microsoft for fwutil update all state that all firmwares which support this upgrade flow must support upgrade within a single boot cycle. This conflicted with a number of Mellanox upgrade flows which have been revised to safely meet this requirement. How I did it Added --no-power-cycle flags to SSD and ONIE firmware scripts Modified Platform API to call firmware upgrade flows with this new flag during fwutil update all Added a script to our reboot plugin to handle installing firmwares in the correct order with prior to reboot How to verify it Populate platform_components.json with firmware for CPLD / BIOS / ONIE / SSD Execute fwutil update all fw --boot cold CPLD will burn / ONIE and BIOS images will stage / SSD will schedule for reboot Reboot the switch SSD will install / CPLD will refresh / switch will power cycle into ONIE ONIE installer will upgrade ONIE and BIOS / switch will reboot back into SONiC In SONiC run fwutil show status to check that all firmware upgrades were successful
