Disclosed in some examples are methods, systems, devices, memory controllers, memory dies, memory devices, and machine-readable mediums that allow for efficient updating of software instructions of the memory die. In some examples, the controller of the memory device may cause the software instructions of one or more memory dies to be updated by causing the page buffers of the one or more memory dies to be loaded with updated software instructions and subsequently issuing a command to the memory die to update the software instructions from the page buffer.

A programmable memory device includes a read only memory (ROM) block to store instructions associated with functionality of the programmable memory device. The device includes a memory array having a set of reserved pages to store updates to be performed on the ROM block. The device includes a controller coupled to the ROM block and the memory array. The controller is to execute the instructions to: execute a set features command; program, in execution of the set features command, a set of sub-feature parameters to a specified feature address of the set of reserved pages, wherein the set of sub-feature parameters are to trigger operation within a ROM-emulated memory (REM) profile mode; and program a REM-profiled page of the set of reserved pages with REM data received from a host system.

Systems and methods are described for adapting a second user input device to resemble a first user input device while preserving new functionalities not available in the first user input device. The systems and methods may identify, based on identifiers of the first and second user input devices, a first and second set of device functionalities provided by the devices. The systems and methods may compare the sets of device functionalities to determine a set of common device functionalities and, in response, modify the display of an input of the second user input device to correspond to visual attributes of an input of the first user input device.

Disclosed embodiments relate to performing updates to Electronic Control Unit (ECU) software while an ECU of a vehicle is operating. Operations may include receiving, at the vehicle while the ECU of the vehicle is operating, a software update file for the ECU software; writing, while the ECU is operating, the software update file into a first memory location in a memory of the ECU while simultaneously executing a code segment of existing code in a second memory location in the memory of the ECU; and updating a plurality of memory addresses associated with the memory of the ECU based on the software update file and without interrupting the execution of the code segment currently being executed in the second memory location in the memory of the ECU.

An embodiment of the present application discloses a method for patching a chip and a chip. The chip includes a first program, and the method includes: when a function that needs to be replaced in the first program is run, executing an interrupt service routine according to a pre-stored correspondence relationship between an address of the function that needs to be replaced and an interrupt instruction, where the interrupt service routine is a service routine scheduled by an interrupt instruction corresponding to the function that needs to be replaced, and a return address of the interrupt service routine is an address of a patch function of the function that needs to be replaced; and running the patch function according to the address of the patch function, to perform patch processing on the first program.

A patching method includes generating an original image through compilation for a plurality of files. If a first file in the plurality of files changes, a new index mode of the first file or new data of the first file may be appended to an end of an original image to update the first file to obtain a new image.

A method includes storing, on immutable memory, a first separately compiled portion of an OS, the first separately compiled portion having a first OS section including a patch hook having a patch lookup table address and associated with a first index value, and a second OS section including the patch hook associated with a second index value, storing, on mutable memory, a second separately compiled portion of the operating system, the second separately compiled portion including a patch lookup table at the patch lookup table address. The first and the second separately compiled portion are linked to form the OS. A determination is made that a change is required in the first OS section of the first separately compiled portion, resulting in updating the second separately compiled portion to include a first patch for the first OS section at a first patch address, and updating the patch lookup table.

An updating system includes a plurality of electronic control units and an updating management device. The updating management device is configured to request that the electronic control units respectively update programs and store update results of the programs transmitted from the electronic control units. The electronic control unit has a first storage region and a second storage region, and is configured to store an updated program in the second storage region and notify the updating management device of the update results according to a request from the updating management device, and is configured to start a predetermined control using the updated program stored in the second storage region when the update results stored in the updating management device indicate that the updating of the programs in the electronic control units is completed.

A vehicle control apparatus including: a storage portion configured to store therein a vehicle control software for controlling a vehicle; an updating portion configured to update the vehicle control software stored in the storage portion, to an update software, and an operation check portion configured, when the update software is stored in the storage portion, to make an operation check as to whether the vehicle operates normally or not, by executing processing of the update software on condition that the vehicle is in a vehicle stopped state in which the vehicle is suppressed from being moved in forward and reverse directions. When it is checked by the operation check portion that the vehicle operates normally with the processing of the update software, the updating portion is configured to update the vehicle control software to the update software.

A method for method of setting up a processing system includes determining availability of user-provided platform information indicative of a first memory platform out of a plurality of memory platforms. In response to determining that the user-provided platform information is available at the first memory platform, a boot loader code is read from the first memory platform. In response to determining that the user-provided platform information is not available, test availability of the boot loader code in another memory platform of the plurality of memory platforms, and read the boot loader code from the another memory platform upon testing the availability of the boot loader code in the another memory platform.
