Abstract

PROBLEM TO BE SOLVED: To remarkably shorten a write-in time by inputting a command from a console, simultaneously erasing/writing a memory board mounting a flash memory and preserving the data from the memory board to a built-in floppy disk. SOLUTION: The command is inputted by the console 18 output means, and a source program file to be written is selected, and the data are transferred from an FD device 9 to a memory 15. A CPU: 14 writes the erase command of the flash memory of the board 13, and simultaneously, power to the memory board 13 is supplied, and an LED: 10 is turned on. The CPU: 14 confirms one by one whether or to the erase of the flash memory of the memory board 13 is completed. The data from the FD device 9 downloaded to the memory 15 are written simultaneously in plural sheets of the flash memory of the memory board 13, and after confirming it, write-in is finished.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a writing device for a memory board on which a flash memory is mounted.

[0002]

2. Description of the Related Art Conventionally, a flash memory writer of a QFP memory downloads a source program to be written from a personal computer, inserts the memory into a QFP socket built in the flash memory writer, and performs writing. It was implemented later.

[0003]

However, in the conventional method, a personal computer or a CRT terminal is absolutely necessary, and it is necessary to rewrite the flash memory by changing the source program in a place where the personal computer or the CRT terminal is not provided due to a business trip. It is very inconvenient when you want to save the memory data suddenly,
Furthermore, it takes a considerable amount of time to write data one by one during mass production. SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and aims to solve these disadvantages and to provide a floppy disk drive to this device when traveling.
With the built-in disk unit, connect a console to this unit, insert the floppy disk containing the source program you want to write into the floppy disk unit built in this unit, and enter commands from the console By doing so, writing to the flash memory can be performed, and the flash memory or SR
The data can be saved from the memory board on which the AM is mounted to the floppy disk by the built-in floppy disk device, and the write time is reduced in consideration of the production lot at the time of mass production. It is intended to provide a flash memory writer device capable of performing such operations.

[0004]

Means for achieving the object is to connect a CRT terminal to a communication cable to download and write a source program from a built-in floppy disk. In the memory writer device: a) console output means for inputting a command from a console; b) erasing means for providing a console in place of the CRT terminal and simultaneously erasing a memory board on which a flash memory is mounted; c) flash Writing means for simultaneously writing data on a memory board on which a memory is mounted; d) a floppy disk from a memory board on which a flash memory or an SRAM is mounted by using a floppy disk device incorporating the data; Keep And a storage means. Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0005]

FIG. 1 is a block diagram showing an embodiment of the present invention, FIG. 2 is a flowchart of a command A, and FIG. The apparatus comprises: a) console output means for inputting a command from a console; b) erasing means for providing a console in place of the CRT terminal and simultaneously erasing a memory board on which a flash memory is mounted; c) flash Writing means for simultaneously writing data on a memory board on which a memory is mounted; d) a floppy disk from a memory board on which a flash memory or an SRAM is mounted by using a floppy disk device incorporating the data; And storage means for storing data in the storage device.

Next, the function of the present apparatus will be described with reference to FIG. Console 18 for communication with console
, And when the power switch 11 is turned on, the LED 10 is turned on. Further, a floppy disk containing a program source to be written is inserted into the floppy disk device 9. A memory board 13 on which a flash memory is mounted is inserted into the apparatus.

First, in FIG. 2, a command A is input by the console 18 output means (step 101), a source program file to be written is selected, and data is transferred from the floppy disk device 9 to the memory 15. When transferring this data, the total value A of the data
Get it. (Hereafter the sum is called sum)
(Step 102) Next, the CPU 14 flashes the memory board 13
A memory erase command is written (hereinafter, erase is referred to as erase). At this time, power is supplied to the memory board 13 and the LED 10 is turned on. This LED1
While 0 is lit, the removal and insertion of the memory board 13 is prohibited. Next, the CPU 14 checks one by one whether the erasing of the flash memory on the memory board 13 is completed. (Step 103)

Next, the data downloaded from the floppy disk drive 9 to the memory 15 is stored in the memory board 1.
A plurality of flash memories are simultaneously written into the flash memory No. 3. At the time of data transfer from the memory 15 to the flash memory of the memory board 13, the data sum value B
Is obtained and compared with the previously obtained sum value A. If the sum is not correct, an error is displayed on the console 18 and the processing ends. (Steps 104, 105, 110)

After the writing is completed, the CPU 14
It is checked one by one whether the data No. 5 and the data in the flash memory of the memory board 13 match. If not correct, an error is displayed on the console 18 and the processing ends.
(Steps 106 and 111) If correct, the data in the memory 15 and the memory board 13
In the comparison with the data in the flash memory, the sum value C of the acquired data is compared with the previously acquired sum value B, and if incorrect, an error is displayed on the console 18 and the processing is terminated. (Steps 107, 108, 112) If the sum is correct, the sum C is written into the flash memory of the memory board 13, and the process is completed. (Step 10
9)

In FIG. 3, once data is transferred from the floppy disk device 9 to the memory 15, the data and the sum value A of the data remain in the memory 15 unless the power switch 11 is turned off. This eliminates the need to download the source program from the floppy disk drive 9 every time data is written to the flash memory of the memory board 13. By starting the command B after replacing the memory board 13 on which the flash memory is mounted, it is possible to greatly reduce the time required for writing. Note that the same operation as that using the console 18 can be performed even by using the personal computer 17 or the CRT terminal. In addition, the present apparatus has a built-in floppy disk device 9 and, by inputting a command from the console 18, makes it possible to save data on the memory board 13 on which the flash memory is mounted to a floppy disk. .

[0011]

As described above, according to the present invention, a flash memory writer is provided with a floppy disk device and communication by a console is added, so that a flash can be performed by a console without using a personal computer or a CRT terminal. A memory write operation, and a floppy that incorporates the data from a memory board on which a flash memory or an SRAM is mounted.
The disk unit has made it possible to save data to floppy disks. Also, multiple flash
Since writing to a memory board on which a memory is mounted is possible, the writing time during mass production can be significantly reduced, and is extremely useful in practical use.
