All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first", "second", and the like in the present invention are used for distinguishing different objects, not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The power management chip of the mobile terminal such as the smart phone can integrate a battery in-place detection function, after the mobile terminal is connected with the charging device, when the mobile terminal detects that the battery is in place, the power management chip controls the charging device to supply power to the mobile terminal to a first current value, and when the mobile terminal detects that the battery is not in place, the power management chip controls the charging device to supply power to the mobile terminal to a second current value, wherein the first current value is larger than the second current value.
The mobile terminal comprises a terminal main body and a battery, wherein the battery is in place, namely the battery is connected with the terminal main body, and the battery is not in place, namely the battery is not connected with the terminal main body.
Through the mode, the charging equipment can supply power to the mobile terminal by using smaller current when the battery is not in place, and the mobile terminal is supplied by using larger current when the battery is in place, so that the safety of a user when the user uses the mobile terminal can be ensured.
In a development and test stage of the mobile terminal, for example, when a main board of the mobile terminal is tested, a battery of the mobile terminal cannot be connected with a terminal main body, that is, the battery is usually in a state of not being in place, however, a power management chip on the main board still can detect whether the battery is in place, so that the power management chip can detect that the battery is not in place in the development and test stage, when a firmware is downloaded by a main board connected with an upper computer, the current for supplying power to the main board by the upper computer is set to be a second current value, and the relatively small second current value is not enough for the main board to complete the firmware downloading from the upper computer, which generally causes downloading failure, and brings great inconvenience to development and test work.
According to the embodiment of the invention, the power supply current provided by the upper computer to the mobile terminal is set as the first current value before the mobile terminal downloads the firmware from the upper computer, so that the smooth burning of the firmware in the development and test stage of the mobile terminal can be ensured.
According to the embodiment of the invention, after the mobile terminal finishes downloading the firmware from the upper computer, the power supply current provided by the upper computer to the mobile terminal is set to be the first current value or the second current value according to the second judgment strategy, so that the use safety of the mobile terminal can be ensured.
See in particular the detailed description in the examples below.
Referring to fig. 1, fig. 1 is a flowchart illustrating a current setting method of a mobile terminal according to a first embodiment of the present invention. In this embodiment, the current setting method of the mobile terminal may include the steps of:
step 11: before the mobile terminal downloads the firmware from the upper computer, the power supply current provided by the upper computer to the mobile terminal is set to be a first current value.
In step 11, for example, in a development and test phase of the mobile terminal, a main board of the mobile terminal establishes a power supply connection and a communication connection with the upper computer. After the power supply connection and the communication connection are established, in a time period before the downloading of the firmware is started, the current for supplying power to the mobile terminal by the upper computer is set to be a first current value.
The upper computer may be a PC (personal computer). The main board of the mobile terminal and the upper computer may be connected through a USB (Universal Serial Bus) interface for establishing power supply connection and communication connection. After the main board establishes the USB connection with the upper computer, the first boot program may be triggered to run, and then the first boot program calls the second boot program, and then the second boot program is executed to execute the downloading of the firmware from the upper computer.
The step of setting the power supply current provided by the upper computer to the mobile terminal to the first current value may be completed during the execution of the first boot program.
Alternatively, a step of setting the supply current provided by the upper computer to the mobile terminal to the first current value may be added to the first boot program by modifying the first boot program.
The first Boot program may be a PBL (Primary Boot Loader) and the second Boot program may be a firmware download Boot program.
Optionally, the setting of the power supply current provided by the upper computer to the mobile terminal as the first current value may specifically be: and judging whether the battery of the mobile terminal is in place or not, and setting the power supply current as a first current value when the battery is judged to be in place or not.
Optionally, determining whether the battery is in place may include: judging the state value of a battery state bit pin of a power management chip of the mobile terminal; if the state value is the first state value, the battery is in place; and if the state value is the second state value, the battery is not in place.
For example, a pull-down resistor is connected to a status bit detection pin of the power management chip, i.e., the status bit detection pin is grounded through the pull-down resistor.
When the battery is in place, the state bit pin of the battery is connected with the state bit detection pin, and the state value of the state bit detection pin is pulled down to a low level at the moment, namely, if the detected state value is the low level, the battery is in place.
When the battery is not in place, the state bit pin of the battery is suspended, and the state value of the state bit detection pin is at a high level at the moment, namely if the state value is detected to be at the high level, the battery is not in place.
The above is merely an example, and in other embodiments, the design of the hardware circuit may be changed to indicate that the battery is not in place when a low level is detected and to indicate that the battery is in place when a high level is detected.
In the beginning, namely after the power supply connection and the communication connection are established between the mobile terminal and the upper computer and in a time period before the firmware starts to be downloaded, no matter whether the battery is in place or not is detected by the status bit detection pin of the power management chip, the power management chip sets the power supply current of the upper computer serving as the mobile terminal to be the first current value.
Step 12: after the mobile terminal finishes downloading the firmware from the upper computer, setting the power supply current provided for the mobile terminal by the upper computer to be a first current value or a second current value according to a preset judgment strategy, wherein the first current value is larger than the second current value.
In step 12, as mentioned earlier, for example, after the execution of the second boot program is finished, the power supply current provided by the upper computer to the mobile terminal is set to the first current value or the second current value according to the preset judgment policy.
Setting the supply current provided by the upper computer to the mobile terminal as the first current value or the second current value according to the preset judgment strategy may specifically be: judging whether a battery of the mobile terminal is in place; when the battery is judged to be in place, setting the power supply current as a first current value; and when the battery is judged not to be in place, setting the power supply current to be a second current value. For how to judge whether the battery is in place, see the above description, and it is not repeated here.
Referring to fig. 2, fig. 2 is a flowchart illustrating a current setting method of a mobile terminal according to a second embodiment of the present invention. In this embodiment, the current setting method of the mobile terminal may include the steps of:
step 21: and establishing communication and power supply connection with the upper computer.
In step 21, the upper computer may be a PC terminal, and may be a motherboard of the mobile terminal that establishes a USB connection with the PC terminal through a USB interface.
During connection, on one hand, the PC end can supply power for a mainboard of the mobile terminal through a VBUS pin of the USB interface, and on the other hand, the PC end can communicate with the mainboard through a data line positive electrode pin D + and a data line negative electrode pin D-of the USB interface in the subsequent downloading process.
Step 22: and setting the power supply current provided by the upper computer to the mobile terminal as a first current value while running the first bootstrap program.
In step 22, when the USB plug is plugged into the motherboard, a first boot program of the motherboard is triggered to run, where the first boot program may be a master boot program, as described above.
The power management chip is powered on and initialized through the operation of the first bootstrap program, and then hardware related to the downloaded firmware is initialized and powered on, so that the subsequent firmware downloading process is ensured to be carried out smoothly.
For example, the USB communication function is initialized, the memory is initialized and powered on, and a DDR (Double Data Rate) synchronous dynamic random access memory (DDR) is initialized and powered on by running the first boot program, so that the initialization of the USB communication function, the storage function of the memory, and the like required in the downloading process is completed, and the firmware can be downloaded to the memory through USB communication in the subsequent firmware downloading process.
And setting the power supply current provided by the upper computer to the mobile terminal as a first current value while the first boot program performs initialization and power-on of hardware related to downloading of firmware.
Optionally, setting the power supply current provided by the upper computer to the mobile terminal to the first current value may specifically be: and judging whether the battery of the mobile terminal is in place or not, and setting the power supply current as a first current value when the battery is judged to be in place or not.
Optionally, determining whether the battery is in place may include: judging the state value of a battery state bit pin of a power management chip of the mobile terminal; if the state value is the first state value, the battery is in place; and if the state value is the second state value, the battery is not in place.
For example, a pull-down resistor is connected to a status bit detection pin of the power management chip, i.e., the status bit detection pin is grounded through the pull-down resistor.
When the battery is in place, the state bit pin of the battery is connected with the state bit detection pin, and the state value of the state bit detection pin is pulled down to a low level at the moment, namely, if the detected state value is the low level, the battery is in place.
When the battery is not in place, the state bit pin of the battery is suspended, and the state value of the state bit detection pin is at a high level at the moment, namely if the state value is detected to be at the high level, the battery is not in place.
The above is merely an example, and in other embodiments, the design of the hardware circuit may be changed to indicate that the battery is not in place when a low level is detected and to indicate that the battery is in place when a high level is detected.
Step 23: and calling the second bootstrap program through the first bootstrap program to execute the downloading of the firmware from the upper computer.

Step 24: after the mobile terminal finishes downloading the firmware from the upper computer, setting the power supply current provided for the mobile terminal by the upper computer to be a first current value or a second current value according to a preset judgment strategy, wherein the first current value is larger than the second current value.
In step 24, as mentioned earlier, for example, after the execution of the second boot program is finished, the power supply current provided by the upper computer to the mobile terminal is set to the first current value or the second current value according to the preset judgment policy.
Setting the supply current provided by the upper computer to the mobile terminal as the first current value or the second current value according to the preset judgment strategy may specifically be: judging whether a battery of the mobile terminal is in place; when the battery is judged to be in place, setting the power supply current as a first current value; and when the battery is judged not to be in place, setting the power supply current to be a second current value.
After the second boot program is executed, a third boot program or other boot programs may be further executed, so as to complete power-on and initialization of each hardware (e.g., a baseband processing chip, an application processing chip, a radio frequency module, etc.) on the motherboard, start running the downloaded firmware after each boot program is executed, and perform each test of the motherboard.
Alternatively, the first current value may be 500mA and the second current value may be 100 mA.
In other embodiments, the current for supplying power to the mobile terminal by the upper computer may be set to the first current value in any time period within a time period before the start of downloading the firmware after the mobile terminal establishes the power supply connection and the communication connection with the upper computer, and is not limited to setting the current for supplying power to the mobile terminal by the upper computer to the first current value in the process of executing the first boot program, as long as the power supply current is set to the first current value before downloading the firmware, which is specifically referred to the description below.

Step 32: when a first control instruction of the upper computer is received, the power supply current provided for the mobile terminal by the upper computer is set to be a first current value.
In step 32, as mentioned above, the tester may input the first control instruction to the upper computer before the motherboard downloads the firmware, the upper computer sends the first control instruction to the power management chip, and when the power management chip receives the first control instruction, the power management chip sets the supply current of the power management chip, which is the mobile terminal, to the first current value regardless of whether the power management chip determines that the potential on the battery state detection pin of the power management chip is a high level or a low level.
