Embodiment 1
[0047] Such as figure 2 As shown, the firmware upgrade process of a compatible multi-model MCU according to an exemplary embodiment includes:
[0048] Step 202, after the smart TV is turned on, the CPU sends a version number query request to the MCU.
[0049] Step 204, in response to the version number query request, the CPU receives the current firmware version number fed back by the MCU.
[0050] In step 206, the CPU judges the model of the MCU according to the current firmware version number.
[0051] Specifically, different value ranges of version numbers are pre-configured for MCUs of different models. For example, for example, a smart TV manufacturer has purchased three types of MCU chips, namely MCU1, MCU2, and MCU3, where the value range of the version number corresponding to MCU1 is [1,100], and the value range of the version number corresponding to MCU2 is [ 101,200], the value interval of the version number corresponding to MCU3 is [201,300]. Among them, the ab...
Embodiment 2
[0061] Such as image 3 As shown, the firmware upgrade process of a compatible multi-model MCU according to another exemplary embodiment includes:
[0062] Step 302, when the smart TV is turned on for the first time, the CPU obtains the version number of the pre-burned firmware in the MCU.
[0063] Step 304, the CPU judges the chip model of the MCU according to the version number of the pre-programmed firmware. Specifically, the judgment method is similar to figure 2 Step 206 shown will not be repeated here.
[0064] In step 306, as an example, assuming that the chip model of the MCU is determined to be MCU2, the model is stored in the eMMC.
[0065] Step 308, similar to figure 2 In step 202 shown, after the smart TV is powered on for a certain time, the CPU initiates a version number query request to the MCU.
[0066] Step 310, if the MCU does not respond to the version number query request initiated by the CPU (specifically, such as within a predetermined time), obtai...

Abstract
The invention provides a firmware upgrading method and device of a chip. The firmware upgrading method includes the steps that a current firmware version number of the chip is acquired; a version number numerical value interval which the current firmware version number belongs to is determined; the model of the chip is judged according to the corresponding relation between a pre-configured version number numerical value interval and the model of the chip; a latest firmware version number corresponding to the model of the chip is inquired from a pre-configured firmware upgrading file storage path; when the firmware version corresponding to the latest firmware version number is higher than the firmware version corresponding to the current firmware version number, firmware upgrading operation to the chip is executed according to a firmware upgrading file corresponding to the latest firmware version number. According to the technical scheme, corresponding version number numerical value intervals are set for the chips of different models, the model of the current chip in equipment can be accurately recognized, and accordingly the firmware upgrading operation to the chip is achieved smoothly.
Description
technical field [0001] The invention relates to the technical field of computers, in particular to a chip firmware upgrading method and a firmware upgrading device. Background technique [0002] Firmware (firmware) is the software that often performs the most basic and lowest-level work, and is generally stored in the EEPROM (Electrically Erasable Programmable ROM) or FLASH chip in the chip. Even for chips used to perform the same function, when the manufacturers are different, the firmware upgrade methods and files of the corresponding chips are completely different. [0003] However, in the production process of the equipment, due to chip supply problems, the same type of equipment often uses multiple types of chips from multiple chip suppliers at the same time, but the related technology does not provide compatible support for multiple types of chips at the same time. Upgrade method. Contents of the invention [0004] In view of this, the present invention provides a ...
