Problems solved by technology
However, the upgrade module is also a software code, so it is inevitable that various problems or defects will occur. When using a solidified upgrade module, if there is a problem with the upgrade module, the only way to update the upgrade module is to return the oscilloscope to the factory for update, and the subsequent firmware will be upgraded. have a very serious impact
Especially when the bootloader is used to upgrade the firmware, when there is a problem with the bootloader, if you want to upgrade, you can only return the instrument to the factory, which brings a very high cost to the subsequent maintenance of the instrument
When it is necessary to upgrade the firmware, it is necessary to return the upgrade module to the factory for upgrade first, and then use the upgrade module to upgrade the firmware. This requires two upgrades to upgrade to the latest firmware version, which is unacceptable to users.

Embodiment Construction
[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
[0025] The inventor considers that since the upgrade module is a software code, if the upgrade module is made flexible instead of fixed or difficult to upgrade, the independence and update of the upgrade module can be realized. Therefore, in the embodiment of the present invention, it is considered to use an upgrade script to realize the upgrade module, realize the separation of the upgrade module and the firmware, and realize the upgrade of the firmware dynamically by the upgrade script. Since the upgrade script is editable, it is easy to modify and maintain, and the...

The invention discloses a firmware upgrade method and device for a measurement instrument. The method comprises the steps that a firmware upgrade package of the measurement instrument is read, whereinthe firmware upgrade package comprises an upgrade script and upgrade package content; and the upgrade script is loaded, and the upgrade script is executed in the mode that description information ofold firmware is acquired, and description information of new firmware is acquired from the upgrade script; an upgrade strategy is selected according to the description information of the old firmwareand the description information of the new firmware; the upgrade package content is analyzed from the firmware upgrade package; and the corresponding upgrade package content is selected and upgraded according to the upgrade strategy, and the old firmware is upgraded to be the new firmware. Through the firmware upgrade method and device, the upgrade script can be utilized to realize firmware upgrade of the measurement instrument; and since the upgrade script is text-editable, modification and maintenance are both easy, and firmware upgrade can be flexibly realized without returning the measurement instrument to a factory.
Description
technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a firmware upgrading method and device for measuring instruments. Background technique [0002] As the firmware of oscilloscopes becomes more and more complex, the firmware upgrades become more and more frequent, especially for newly released oscilloscope products, the firmware upgrades are relatively more frequent, and the common way to upgrade firmware is to read through non-volatile memory The new firmware upgrade package, and then the upgrade module parses the upgrade package to upgrade the firmware. The upgrade module here is either integrated on the firmware before the upgrade, or solidified on the bootloader inside the oscilloscope. However, the upgrade module is also a software code, so it is inevitable that various problems or defects will occur. When using a solidified upgrade module, if there is a problem with the upgrade module, the only way to update t...
