SSU Upgrade Operation Status Command

Remote BMC Firmware Upgrade
Image Upgrade on BMC
Upgrade of the BMC operational code is controlled by the SSUA running on the NPU,
that is, the NPU upgrade agent retrieves a new BMC firmware image from the image
repository and passes it to the BMC using the IPMI driver.
Next, the BMC operational image stores the received image in one of two locations on
its flash as shown in
image selection procedure is based on the image status word. The image status word
for the BMC is supported by the SSUA on the NPU, but its local flash copy must be
present on the BMC for image selection purposes during the BMC Initial Loader phase.
After every modification of this word by either BMC (both operational image and
loader) or the SSUA, it has to be transferred to the other side as soon as
communication between processors is established or possible. The SSUA on the NPU
requests the BMC to read or write the status word.
BMC image status word
After storing the new image, the BMC sends the status of the upgrade operation to the
SSUA on the NPU, and the SSUA passes this status to the SSUM.

Description
This bit is set by the SSUA to force the BMC Loader to load the second image in
safe mode.
If bit is set to 1, the BMC Loader clears this bit and loads the opposite image to
that specified by the “Image selector”.
This bit indicates that current BMC image is started in safe mode, used only as
an indication of boot status, and set by the BMC Loader immediately after
clearing bit 7.
This bit selects an active image to be loaded (either first or second copy). This
bit may be modified only by the SSUA on a control plane validation request.
