Description
Technical Field
The invention relates to a method for starting, upgrading and restoring ADI-DSP firmware with high efficiency and reliability.
Background
At present, with the popularization of ADI-DSP in China, the logic which can be processed by the processor in the equipment development is limited and has no function expansibility, and if a problem or a bug on firmware in the processor is found and the function of an existing product is newly added, the problem can be solved only by upgrading the firmware. At present, when firmware is generally upgraded, a USB flash disk and an SD card which store upgrading data are needed to be used for upgrading the firmware, even upgraded equipment needs to be disassembled, a JTAG simulation mode which is slow in use speed and unstable is used for upgrading the firmware, the traditional firmware uses a mode of single firmware, and the whole DSP firmware needs to be overwritten and burnt again when the firmware is updated every time. In the burning process, once the accidents such as power failure and the like occur to cause the burning failure, the self-recovery cannot be realized, and the maintenance can be carried out only in a simulator burning mode. It can be seen that the conventional maintenance method increases the maintenance cost of the equipment.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the defects of the prior art and provide a method.
In order to solve the technical problems, the invention provides an efficient and reliable ADI-DSP firmware starting, upgrading and restoring method, which comprises an LDR firmware area, and is characterized in that the LDR firmware area comprises Bootloader firmware, Backup firmware and APP firmware; the Bootloader firmware is used for configuring basic initialization of a system and selecting boot firmware, the Bootloader firmware starts the APP firmware firstly, and when the APP firmware cannot be started normally, the Backup firmware is started again.
Furthermore, when the Bootloader firmware normally starts the APP firmware, the USB DEVICE function is realized, the USB DEVICE is connected with a PC (personal computer) to perform data communication, and an upper computer is used for firmware upgrading.
Further, the data communication uses a USB2.0 interface, the USB2.0 DEVICE function is realized at the machine tool end, and the data communication of different domains is carried out by using two communication modes of Bulk and interrupt.
Furthermore, when the Bootloader firmware normally starts the APP firmware, after the system is started, the firmware version is read and compared with the local firmware version, whether the firmware needs to be upgraded or not is judged, or an administrator development tool is used for upgrading the firmware, and the version number does not need to be matched.
Furthermore, when the Bootloader firmware cannot normally start the APP firmware, the Bootloader firmware guides the Backup firmware to start, the Backup firmware realizes a USB DEVICE function, is connected with a PC (personal computer), uses an upper computer to upgrade the firmware, burns the normal firmware to the APP firmware position again, and after burning succeeds, the machine normally starts the APP firmware.
Further, in the system restoring mode, the service system judges that the product enters the restoring mode, and automatically performs firmware solidification and upgrade work, or performs firmware solidification by using an administrator development tool. The invention achieves the following beneficial effects:
1) the traditional single firmware is divided into three parts of firmware, and only APP firmware needs to be updated when the firmware of the occasions such as normal business upgrading, BUG repairing and the like is upgraded;
2) USB upgrading can be realized in the APP firmware, upgrading speed is increased, and burning steps are simplified;
3) the firmware is backed up on board, and the device never loses the firmware.

Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Referring to fig. 1, an efficient and reliable method for starting, upgrading and restoring an ADI-DSP firmware includes an LDR firmware area, and is characterized in that the LDR firmware area includes Bootloader firmware, Backup firmware and APP firmware; the Bootloader firmware is used for configuring basic initialization of a system and selecting boot firmware, the Bootloader firmware starts the APP firmware firstly, and when the APP firmware cannot be started normally, the Backup firmware is started again.
As shown in fig. 2, the Bootloader firmware normally starts the APP firmware, and this mode is a normal boot and start process of the product, and can implement normal business work and perform data communication with the PC terminal. The communication mode uses a USB2.0 interface, the USB2.0 DEVICE function is realized at the machine tool end, and simultaneously, Bulk and interrupt communication modes are used for data communication of different domains.
After the system is started, the firmware version is read. And compared to the local firmware version. And judging whether the upgrading is needed. Firmware upgrades can also be made using administrator development tools without matching version numbers.
And after the system selects the firmware to be upgraded, issuing a binary file of the new firmware to the machine tool end, and verifying the file. And after the file is successfully issued, the system issues a curing command. The machine tool end solidifies the program into the FLASH. And after the solidification is successful, the system is automatically restarted, and the new version firmware is operated to carry out business work.
The physical connection of the product and the PC end only needs one USB cable.
As shown in fig. 3, when the Bootloader firmware cannot normally start the APP firmware, the Bootloader firmware boots the Backup firmware to start, where this mode is a system restoring state of the product, and in this mode, it is not recommended to support normal business operation, but the USB DEVICE function is also implemented, and data communication can be performed with the PC terminal. In order to ensure the success rate and reliability of system restoration, the USB communication only supports the firmware upgrading function.
And under the system restoring mode, the service system judges that the product enters the restoring mode and automatically performs firmware solidification and upgrading work. Firmware curing may also be performed using an administrator development tool.
The system actively issues the binary file of the local firmware to the machine tool end and conducts file verification. And after the file is successfully issued, the system issues a curing command. The machine tool end solidifies the program into the FLASH. And after the solidification is successful, the system is automatically restarted, and the new version firmware is operated to carry out business work.
The physical connection of the product and the PC end only needs one USB cable.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
