Next, an offline burning apparatus provided by an embodiment of the present invention is described in detail. Fig. 1 is a schematic structural diagram of an offline burning device according to an embodiment of the present invention, where the offline burning device includes a main control chip 1 and a memory chip 2.
The main control chip 1 is provided with a first interface 11 for connecting with an erasable device; a second interface 12 for connection with a host.
In practical applications, the main control chip 1 may be connected to a host through the second interface 12, where the host may be a terminal device used by a manager, such as a PC.
When the second interface 12 of the main control chip 1 is connected with a host, a power supply can be provided to the main control chip 1 by the host. When the second interface 12 of the main control chip 1 is disconnected from the host, the offline burning device can be connected with a power supply through the second interface 12.
The voltage value provided by the host or the power supply is often different from the voltage value required by the main control chip 1, and therefore, a Low Drop Out (LDO) regulator may be disposed between the main control chip 1 and the second interface 12.
In the embodiment of the present invention, the main control chip 1 may adopt an MCU chip, the required voltage value is 3.3V, the voltage value input by the second interface 12 is generally 5V, and the LDO may convert the 5V supply voltage into a 3.3V supply voltage.
In order to realize connection with the erasable device, the first interface 11 may adopt a Joint Test Action Group (JTAG) based JTAG interface. The JTAG interface can be applied to most server models and has good universality. The JTAG interface includes a power supply terminal, JTAG _ TCK, JTAG _ TMS, JTAG _ TDO, JTAG _ TDI, and a ground terminal.
The second interface 12 may be a USB interface including a power supply terminal, D +, D-, and a ground terminal. Fig. 1 is a schematic diagram of a JTAG interface as a first interface 11 and a USB interface as a second interface 12.
The type of erasable Device can be various, for example, the erasable Device can be a Complex Programmable Logic Device (CPLD). The main control chip 1 can realize the connection with the CPLD through the JTAG interface.

When the erasable device needs to be burned, the erasable device can be connected with the first interface 11, and the second interface 12 of the off-line burning equipment can be connected with a power supply so as to ensure the normal work of the off-line burning equipment. When the main control chip 1 is powered normally and is successfully connected with the erasable device, the main control chip 1 can load the burning file stored in the storage chip 2 onto the erasable device to complete the burning work of the erasable device.
Taking version verification as an example, after the PC and the offline burning device are successfully connected, the administrator can select a verification file in the browsing frame on the right side of the version verification, click the version verification button, and send the verification file to the main control chip 1 of the offline burning device, and at this time, the main control chip 1 can store the verification file in the storage chip 2 and adjust the self mode to the verification mode.

When the erasable device needs to be verified, the erasable device can be connected with the first interface 11, and the second interface 12 of the offline burning device can be connected with a power supply, so that the offline burning device can work normally. When the power supply of the main control chip 1 is normal and the main control chip 1 is successfully connected with the erasable device, the main control chip 1 can read the burning file stored in the erasable device and verify the burning file by using the verification file.
The verification process may include detecting whether the version of the burning file is consistent with the version set in the verification file; and whether the parameter specification recorded in the burning file is matched with the parameter specification contained in the verification file or not.
After the master control chip 1 completes the verification of the burning file, the verification result can be recorded, and when the master control chip 1 is connected with the PC again, the verification result can be fed back to the PC.
Taking reverse reading as an example, after the PC and the offline burning device are successfully connected, the administrator can click the "reverse reading" button, and at this time, the main control chip 1 can adjust its own mode to the reading mode.
After the setting of the reading mode is finished, the connection between the PC and the off-line burning device can be disconnected. The off-line burning device can be connected with the erasable device through the first interface 11, and the second interface 12 of the off-line burning device can be connected with the power supply at the moment so as to ensure the normal work of the off-line burning device. When the main control chip 1 is powered normally and is successfully connected with the erasable device, the main control chip 1 can read the burning file stored in the erasable device and store the read burning file to the storage chip 2. When the main control chip 1 is connected with the PC again, the burning file stored in the storage chip 2 can be fed back to the PC, and the manager can store the burning file fed back by the main control chip 1 by clicking the 'file storage' option on the display interface of the PC.
