The alternate BMC chip +can also be used to store images. This is determined by "BMC_RO_MTD". Using both +the alternate BMC chip and the BMC chip allows for multiple BMC images to be +stored. By default, only the BMC chip is used. To use both, set "BMC_RO_MTD" to +"alt-bmc+bmc". + ### Implementation More information about the implementation of the UBI code update can be found at |
