Abstract: Methods and apparatuses for memory device mode selection in a serial memory device are presented. Memory device configuration information may be retrieved in response to a memory device initialization condition, and a configuration register bit mask that is included in the memory device configuration information may then be written to a configuration register of the memory device. A write command that may also be included in the memory device configuration information may be used to write the configuration bit mask to the configuration register. The serial memory device may be a serial flash memory. The configuration register bit mask may include an I/O mode bit setting that indicates enabling the memory to operate in a quad-bit I/O mode or other multi-bit serial I/O mode instead of a single-bit serial I/O mode.

Abstract: Methods of upgrading a mesh network device reduce the amount of memory required on such devices. A network device may identify a neighbor network device in response to receiving a request to perform an upgrade, and send a message configured to cause the neighbor network device to function as a recovery node. The network device may then perform the upgrade without retaining a backup image in memory. If the neighbor network device determines that the upgrade failed based on messages not received from the mesh network device being upgraded, the neighbor network device may recover the network device being upgraded by providing a file corresponding to the upgrade. The neighbor network device may determine that the upgrade failed if no response is received to a challenge message or if no indication of success is received after a time expires.
