Functions ¶
func ActivateHAB ¶
ActivateHAB issues the HAB command to the armored witness via HID.
Types ¶
type Target ¶
type Target struct {
sync.Mutex
// DeviceInfo allows callers to inspect details of the device (e.g. to differentiate
// between multiple units connected at once).
DeviceInfo hid.DeviceInfo
// contains filtered or unexported fields
}
Target represents a valid device to be SDP booted
func BootIntoRecovery ¶
func BootIntoRecovery(ctx context.Context, recoveryFirmware []byte, blockDeviceGlob string) (*Target, string, error)
BootIntoRecovery attempts to boot an armored witness device in SDP (Serial Boot) mode with the recovery firmware image, and then watches for a matching new block device to be presented to the host.
If no armored witness device is present, this function will wait until either a device is plugged in/rebooted into SDP mode by the user, or the context becomes done.
Returns the HID device and detected block device path, or an error.
