Those have different component properties due to its different physical implementation:
7.3.1 FPGA Firmware Upgrade
The HPM1 component FPGA is implemented with tow SPI Flashes, one active and one backup. The IPMC is always writing to the
backup Flash. There is no automatic rollback implemented. The command "Activate Firmware" does not reboot the FPGA
unconditionally.
A payload cold reset is not enough to execute a new FPGA component. In this particular case a power cycle is required.
