Disclosed are exemplary remote programming systems, software and methods for use in remotely programming field devices, such as engines, power generators, controllers, and data sensors, and the like. A (wired or wireless) communications link interconnects a processor and a remotely located server. The processor comprises a program memory and firmware that is loaded into the program memory. The processor is coupled to a nonvolatile memory device and apparatus for communicating over the communications link. The remotely located server contains a source code file comprising updated firmware for the processor. Software or a method is provided that initiates a process wherein the updated firmware is transferred from the server to the processor and the updated firmware is stored in the nonvolatile memory. Once transfer is complete, a checksum is calculated for the transferred file, and if it matches a known checksum value, the updated firmware is transferred from the nonvolatile memory device into program memory and the processor is rebooted.
Apparatus comprising:
A method for use with apparatus comprising a communications link, a processor comprising a nonvolatile code space memory and firmware that is loaded into the nonvolatile code space memory, which processor is coupled to a nonvolatile memory device and apparatus for communicating over the communications link, and a remotely located server configured to communicate with the processor over the communications link and that comprises a source code file comprising updated firmware for the processor, the method comprising:
Software embodied on a non-transitory computer readable medium for updating firmware in a processor that communicates with a remotely located server over a communications link, the processor comprising a nonvolatile code space memory, and being coupled to a nonvolatile memory device and a radio for communicating over the communications link, the software comprising:
