Class
FwupdPluginCfiDevice
Description [src]
class FwupdPlugin.CfiDevice : FwupdPlugin.Device
implements Fwupd.Codec {
/* No available fields */
}A chip conforming to the Common Flash Memory Interface, typically a SPI flash chip.
Where required, the quirks instance IDs will be added in ->setup().
The defaults are set as follows, and can be overridden in quirk files:
PageSize: 0x100SectorSize: 0x1000BlockSize: 0x10000
