It is a figure which shows the example of data memorize | stored in ROM of a data processing part. It is a figure which shows the processing flow of information processing apparatus.

Hereinafter, an information processing apparatus according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a first block diagram showing the configuration of the information processing apparatus according to the embodiment.
In this figure, reference numeral 1 denotes an information processing apparatus. The information processing apparatus 1 can be applied to, for example, a mobile phone device, a smartphone, a game machine, a tablet PC, a notebook PC, and the like. The information processing apparatus 1 includes a control processing unit 110, an operation confirmation unit 111, and a control target 2. In the present embodiment, it is assumed that the control target 2 is a touch panel device. However, instead of the touch panel device, another input device, another processing unit, or the like may be configured as the control target 2.

Hereinafter, the control target 2 will be described as the touch panel device 2.

FIG. 2 is a second block diagram showing the configuration of the information processing apparatus 1 according to the embodiment.
Next, details of the functions of the information processing apparatus 1 will be described with reference to FIG.
As shown in FIG. 2, the information processing apparatus 1 includes a data processing unit 10 that performs various data processing, and a touch panel device 2 that detects contact of a living body such as a user's finger with a touch panel and a contact position in a detection range on the touch panel. The display device 3, which is stacked on the touch panel and controls display output of display information, the radio circuit / modem 5, the power source 6, and the input device 7 are configured as main functions.
The data processing unit 10 includes a processor 11, a RAM 12, and a ROM 13 (storage unit) configured to include the control processing unit 110 and the operation confirmation unit 111 described in FIG. 1.

The touch panel device 2 includes a touch panel 21, a CPU 22 that controls the touch panel 21, and a memory 23. Here, the memory 23 is assumed to be volatile. Touch panel firmware used for controlling the touch panel device 2 is stored in the ROM 13 in advance. The CPU 22 of the touch panel device 2 reads and executes the touch panel firmware via the bus 4 when the information processing apparatus 1 is activated.
The processor 11, the RAM 12, the ROM 13, the touch panel device 2, and the display device 3 constituting the data processing unit 10 are connected via a bus 4 that relays signals.

FIG. 3 is a diagram showing an example of data stored in the ROM 13 of the data processing unit.
As shown in this figure, the storage area of the ROM 13 stores an update process program area 131 that stores a program used for an update process of a predetermined program, and a program that realizes the functions of the information processing apparatus 1. The execution program area 132, the touch panel firmware area 133 storing the touch panel firmware (pre-update program) transferred to the touch panel device 2 at startup, and the update program (update program) temporarily when executing the program update An update program area 134 to be stored, a touch panel firmware area 135 to store touch panel firmware before update (program before update) at the time of update processing, and a data area 136 to store data for realizing the device function. It is assumed that an update flag indicating whether or not a predetermined program (touch panel firmware in this embodiment) is updated to an updated program is stored in the data area. More specifically, the update flag is set to “update” during the program update process, and otherwise holds a value indicating “normal”. When the update flag is a value indicating “update”, it indicates that the program is updated to the updated program.
The ROM 13 is a non-volatile memory, but is a device that can be erased and rewritten by following a predetermined procedure from the processor 11, such as a NAND flash memory.

FIG. 4 is a diagram illustrating a processing flow of the information processing apparatus 1.
Next, details of the processing of the information processing apparatus 1 according to the present embodiment will be described in order.
First, the information processing apparatus 1 is instructed to output power to the power supply 6 based on pressing of a start switch provided in the information processing apparatus 1. Then, the control processing unit 110 reads the update flag stored in the data area 136 of the ROM 13. Then, the control processing unit 110 determines the value indicated by the read update flag (step S101), and performs normal startup processing when the marching flag indicates “normal” (step S102).

  When performing the activation process, the control processing unit 110 initializes hardware and reads a program necessary for activation from the ROM 13. At this time, the control processing unit 110 reads the touch panel firmware from the touch panel firmware area 133 of the ROM 13 and transfers it to the touch panel device 2 via the bus 4 (step S103). When the CPU 22 of the touch panel device 2 inputs touch panel firmware, the touch panel firmware is stored in the memory 23. Then, the information processing apparatus 1 is activated by the process at the time of activation of the processor 11 (step S104).

  When the information processing apparatus 1 is activated, processing is performed based on a user operation and each program. Assume that the control processing unit 110 detects the start of the program update of the touch panel firmware at a certain timing. Then, the control processing unit 110 starts touch panel firmware program update processing (step S105). When the process of updating the touch panel firmware program is started, the control processing unit 110 first records the touch panel firmware stored in the touch panel firmware area 133 of the ROM 13 in the previous touch panel firmware area 135 in the ROM 13 and backs up the touch panel firmware. Is performed (step S106).

  Then, the control processing unit 110 downloads new touch panel firmware (step S107). For the download, a predetermined download server is accessed via the wireless circuit / modem 5 and a new touch panel firmware is downloaded from the download server. When the new touch panel firmware is downloaded, the control processing unit 110 stores the new touch panel firmware in the update program area 134 of the ROM 13. Then, the control processing unit 110 reads the new touch panel firmware from the update program area 134 and records it in the touch panel firmware area 133, thereby updating the stored original touch panel firmware to the new touch panel firmware ( Step S108).

  When the update in step S108 is completed, the control processing unit 110 rewrites the update flag stored in the data area 136 from “normal” to “update” (step S109). And the control process part 110 starts a restart process (step S110).

  The information processing apparatus 1 is restarted by the restart process. At the time of restart, the control processing unit 110 reads the update flag stored in the data area 136 of the ROM 13. Then, the control processing unit 110 proceeds to step S101, and determines the value indicated by the read update flag. Here, in step S109, the update flag is rewritten to “update”. Therefore, the update flag indicates “update”. When the update flag indicates “update”, the control processing unit 110 starts the activation process after updating the program (step S111).

  In the startup process after the program update, the control processing unit 110 first reads the new touch panel firmware after update stored in the touch panel firmware area 133 of the ROM 13 without performing the normal startup process. The new touch panel firmware is transferred to the touch panel device 2 via the bus 4 (step S112). When the CPU 22 of the touch panel device 2 inputs new touch panel firmware, the CPU 22 stores the new touch panel firmware in the memory 23. This completes the transfer of the new touch panel firmware. When the transfer of the touch panel firmware is completed, the control processing unit 110 instructs the operation check unit 111 to start the operation check process.

  Next, the operation check unit 111 that has received an instruction to start the operation check process reads the operation check time from the ROM 13. Then, the operation confirmation unit 111 starts an operation confirmation process (step S113), and counts down the operation confirmation time (step S114). At this time, the operation confirmation unit 111 controls the display device 3 to display the time from the countdown start to the countdown end (step S115). As a result, the display device 3 performs display in increments of 1 second from the time display of the countdown start (for example, 15 seconds) to the countdown end time (0 seconds). Then, the operation check unit 111 determines whether to input a signal from the touch panel device 2 or input a cancel signal from the input device 7 during the operation check time (step S116).

  Then, the operation check unit 111 does not input a signal from the touch panel device 2 during the operation check time or inputs a cancel signal from the input device 7 during the operation check time. It is determined that the operation of the touch panel device 2 is abnormal. The operation confirming unit 111 determines that it does not apply in any case when no signal is input from the touch panel device 2 during the operation confirmation time or when a cancel signal is input from the input device 7 during the operation confirmation time. In such a case, it is determined that the operation of the touch panel device 2 is normal.

  The control processing unit 110 inputs a signal indicating abnormal operation or normal operation of the touch panel device 2 from the operation confirmation unit 111. When the control processing unit 110 receives a signal indicating an operation abnormality from the operation confirmation unit 111, the control processing unit 110 reads the pre-update touch panel firmware stored in the front touch panel firmware area 135 in the ROM 13 (step S117). Then, the control processing unit 110 rewrites the updated new touch panel firmware stored in the touch panel firmware area 133 with the touch panel firmware before the update (step S118).

  Next, the control processing unit 110 reads the touch panel firmware before update stored in the touch panel firmware area 133 in the ROM 13 and transfers it to the touch panel device 2 via the bus 4 (step S119). When the CPU 22 of the touch panel device 2 inputs the touch panel firmware before update, the CPU 22 stores the touch panel firmware before update in the memory 23. That is, the CPU 22 of the touch panel device 2 rewrites the new touch panel firmware stored in the memory 23 to the touch panel firmware before update (step S120).

  Then, when the new touch panel firmware stored in the memory 23 of the touch panel device 2 is rewritten to the touch panel firmware before update, the control processing unit 110 next displays the update flag stored in the data area 136 in the ROM 13. Rewrite from "update" to "normal" (step S121). Note that the control processing unit 110 also updates the data stored in the data area 136 in the ROM 13 in the same manner as the processing in step S121, even when a signal indicating normal operation of the touch panel device 2 is input from the operation confirmation unit 111. Rewrite the flag from “update” to “normal”. And the control process part 110 performs the process similar to a normal starting process after that. As a result, the information processing apparatus 1 is activated (step S122).

As mentioned above, although embodiment of this invention was described, according to the above-mentioned process, when the program for controlling input devices, such as the touchscreen device 2 used as control object, was updated, it restarts, the said restart Before normal startup processing immediately after startup, it is determined whether or not the operation of the input device operates normally by the updated program. If the operation of the input device due to the post-update program is abnormal, the control is returned to the pre-update program and the input device is controlled.
As a result, it is possible to prevent a situation in which the input device cannot be controlled after normal startup, and any operation cannot be accepted due to program update.
