Class

FwupdPluginCfiDevice

Description [src]

class FwupdPlugin.CfiDevice : FwupdPlugin.Device
{
  /* 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: 0x100
SectorSize: 0x1000
BlockSize: 0x10000
