Referring to FIG. 2, the main memory programming board includes: a power supply unit 110 for supplying power, a code memory 160 storing instructions for operating the programming board, and a command loaded in the code memory 160. CPU 150 for controlling a main memory programming operation, a source memory 170 storing a program stored in a flash memory for main memory programming, and a command loaded in the code memory 160 while the board is operating. Auxiliary memory 180 for storing variables and temporarily storing the downloaded program for upgrading, Target memory unit 190 for mounting a flash memory to produce a main memory device, and visual and auditory operation of the board Intermediate in charge of the communication interface for downloading a file from the outside for an upgrade and the status display unit 120 is not shown It is characterized in that it comprises a face unit 140 and a reset unit 120 that can reset the system as a whole.

The power supply unit 110 supplies a connector 111 for receiving external power at 5V DC and a transformer 112 for converting and supplying 5V DC power input from the connector 111 to 3.3V DC at which the board operates. It is configured to include.

In addition, the state display unit 120 includes eleven LEDs 1 to 11 that visually indicate a work state, and a buzzer 112 for audibly indicating a work state.

The target memory unit 190 is equipped with a target memory (191 ~ 195), which is a plurality of flash memory to be able to produce or upgrade the main memory at a time.

In particular, the auxiliary memory 180 includes a first memory unit 181 which is a temporary storage unit for storing a variable according to a board operation, and a second memory unit 182 which serves as a buffer which is a temporary storage location of a download file for upgrading. The first memory unit 181 may be allocated as much as necessary to store the variable according to the board operation, and the second memory unit 182 may occupy the remaining size of the auxiliary memory 180. It is common to set it.

If the size of the SRAM of the auxiliary memory 180 according to the embodiment of the present invention is 2 Mbytes, the first memory unit 181 may be set to 1 Mbyte, and the second memory unit 182 serving as the download buffer may be set to be 1 Mbyte. Can be.

The operation of the main memory programming board configured as described above operates in a console mode for main memory production and a download mode for upgrading.

3 is a flowchart illustrating an operation procedure of a main memory programming board according to an exemplary embodiment of the present invention.

Referring to FIG. 3, when the connector 111 applies a power of 5V DC from an external power supply (S101), the transformer 112 converts a voltage to 3.3V DC where the board can operate and supplies the voltage to the board (S102). ), The board starts to operate according to the power supply (S103).

When the board operates for the first time, the registers in the CPU 150 are initialized (S104), and the product information of the main memory is grasped (S105). In this case, the main memory is generally a flash memory, and in order to read and write the main memory, it is necessary to know the manufacturer and the product information. To use the products of all companies, the CFI (common flash memory interface) method may be used.

The CFI refers to the contents negotiated by flash memory manufacturers to use flash memory of different companies.

This is because the instructions to read and write in the memory is different according to each manufacturer and product type, it is necessary to read the instructions to read and write the product information from the code memory 160. If the command in the code memory 160 does not support the command according to the product information of the main memory, further operation becomes difficult.

It is assumed that the code memory 160 has instructions according to various manufacturers and product types, and after determining the product information of the main memory, it is checked whether the source memory 170 exists (S106).

The presence or absence of the source memory 170 allows the operation of the board to operate as a main memory production or upgrade.

If there is the source memory 170, the board operates in a console mode for producing a main memory (S107), and if there is no source memory 170, the board operates in a download mode for upgrading a main memory (S108).

Operations in the console mode and the download mode are the same as in FIGS. 4 and 5.

4 is a flowchart illustrating an operation procedure according to the console mode in FIG. 3, and FIG. 5 is a flowchart illustrating an operation procedure according to the upgrade mode in FIG. 3.

Referring first to the operation of the console mode with reference to Figure 4, it is checked whether there is a target memory (S201), if there is a target memory to determine whether it is normal from the first target memory 1 (191) (S202, S203), the target memory If 1 191 is normal, the contents of the target memory 1 191 are deleted (S204). At this time, if the target memory 1 191 is not normal, an error of the target memory 1 191 is notified by using the LEDs 1 to 11 121 and the buzzer 122 of the status display unit 120 (S212). If the next target memory 2 192 is present, it is checked whether the next target memory 2 192 is normal (S203).

In addition, as described above, variables generated according to a board operation according to a command of the code memory 160 while the console mode is operating are temporarily stored in the first memory unit 181 allocated to the auxiliary memory 180 to operate. Done.

When the deletion of the target memory 1 191 is normally terminated, the contents of the source memory 170 are copied to the target memory 1 191, but the copy of the target memory 1 191 is not performed properly. In step 120, the next target memory is checked and the process is repeated from step S203.

In addition, when copying is normally completed (S27), the end of the copy operation of the target memory 1 191 is notified (S208), and the next target memory 2 209 is searched to repeat the delete and copy operations.

After programming of all target memories mounted on the target memory unit 190 is finished, the status display unit 120 notifies all administrators of the end of the work.

As described above, by mounting a plurality of target memories in the target memory unit 190 and checking the errors in turn, by copying the contents of the source memory, the LED or the buzzer while the administrator sees other tasks with the effect of producing several main memory devices at once. You can tell the work progress by sound.

In addition, the administrator monitor of the system may display the target memory and the work progress state in progress in more detail, so that the administrator can easily understand the state.

On the other hand, in the upgrade mode without the source memory 170 is shown in FIG.

Referring to FIG. 5, the board must first set up a communication interface for program download, depending on whether it is LAN communication or serial communication (S301), and when using the LAN communication interface unit 141, set an IP address (S303). In order to use serial communication through the serial communication port 142, a baud rate and a port are set (S302). At this time, the serial communication port may use a general RS323 port.

When the communication preparation is completed as described above, it is checked whether the state of the first target memory 1 is normal among the plurality of target memories (S304). If the state is normal, the contents of the target memory 1 191 are deleted, and the state is normal. If not, an error is notified (S305) and the next target memory 2 (192) to check the status to work.

When the deletion operation of the target memory 1 191 is normally completed, the download is started. In an embodiment of the present invention, the Z-modem protocol, which is most used as a file transfer protocol, is operated to ensure the speed and stability of the download. In operation S308, when 1 Mbyte set in the second memory unit 182 allocated to the auxiliary memory 180 is received (S310), an Xoff signal, which is a signal for requesting to stop transmission, is transmitted to the data transmitting side (S310). In operation S311, 1 Mbyte of data received in the target memory 191 is stored.

After the data storage is completed in the target memory 191, it is checked whether all data to be received are received (S312). If the data reception is completed, the upgrade of the target memory 191 is completed through the status display unit 120. Notify the manager (S313), and if the data reception is not completed, and transmits the Xon message to continue transmitting the next data (S314).

After receiving the Xon message, the transmitter continuously transmits the next data. When receiving 1 Mbyte, the board transmits the Xoff message again (S310), and repeats the operation of storing the data in the target memory 191.

When the upgrade operation is completed in one target memory, the board searches for the next target memory and repeats the download operation to complete the upgrade of all the target memories and informs the manager through the status display unit 120 (S318).

In addition, the notification of the error or the completion of the operation in more detail in the management monitor in addition to the method of notifying the administrator visually and audibly in the status display unit 120 including the LED (1-11) 121 and the buzzer (122). Downloading status and error status are displayed so that the administrator can easily grasp the status.

As described above, in the main memory programming board and the program method according to the present invention, the production or upgrade of the main memory using the existing main memory programming board is performed by mounting the flash memory one by one, and the administrator continues the state. In order to be able to proceed with the production or upgrade work by installing a large number of flash memory at a time, and to notify the administrator visually and aurally about the flash memory error and operation error and progress of work status. It makes the management easier, and when upgrading, it is possible to simply download and upgrade the program by using universal communication method such as serial communication or LAN communication. It is more effective to ensure easy to manage work.
