S13: and executing corresponding reading operation on the USB flash disk assembly according to the upgrading state, so that the indicator lamp in the USB flash disk assembly displays the display state corresponding to the reading operation.
In a specific embodiment, after the upgrade status is determined by the embedded system, an operation of reading data in the usb disk assembly corresponding to the upgrade status is determined according to a preset corresponding relationship, and then the data reading operation is performed on the usb disk assembly, so that an indicator light in the usb disk assembly can display a display status corresponding to the reading operation.
The application is not limited, and the indicator lamp can be set according to the needs of users.
Fig. 2 is a block diagram corresponding to the fault state prompting method of the embedded system according to the embodiment of the present application, where an upgrade program is imported from a U disc component (Udisk) into a DDR of an embedded System (SOC) to run, upgrade firmware in an eMMC device, and use an indicator lamp to quickly output an indication for the upgrade state of the embedded device, as shown in the figure.
The application provides an embedded system upgrade state prompting method, which comprises the following steps: establishing a communication link with the USB flash disk assembly; receiving an upgrade program in the USB flash disk assembly through a communication link so as to upgrade through the upgrade program; determining a corresponding upgrading state according to the upgrading process; and executing corresponding reading operation on the USB flash disk assembly according to the upgrading state, so that the indicator lamp in the USB flash disk assembly displays the display state corresponding to the reading operation. The application adopts the USB flash disk assembly to connect with the embedded system, transmits the upgrade program, has simple software realization, avoids the requirement of WiFi upgrade on the hardware of the embedded system, determines the operation of reading data by different USB flash disk assemblies according to the corresponding upgrade state, further realizes the flashing of the indicator lamp under different upgrade states, has low cost, does not need to be independently provided with a display for the upgrade of the embedded system, simultaneously can be used for upgrading by multiple people, each person can know the upgrade result state by using one USB flash disk assembly, and the equipment upgrade work of multiple areas can be simultaneously carried out.
On the basis of the above embodiment, as a preferred embodiment, before receiving the upgrade program in the usb disk assembly through the communication link to perform the upgrade through the upgrade program, the method further includes:
executing a pre-reading operation on the USB flash disk assembly;
when the accumulated byte number of the pre-read data is larger than the preset byte number; and judging that the current pre-reading operation is in a stable state, and triggering the step of receiving an upgrade program of the USB flash disk assembly through a communication link so as to upgrade the USB flash disk assembly through the upgrade program.
Wherein the pre-read operation includes:
reading the capacity of the USB flash disk assembly;

In a specific embodiment, when the embedded system performs data reading and writing operation on the USB flash disk assembly, the corresponding indicator lamps in the USB flash disk assembly flash prompts; when the data reading and writing operation is not performed on the USB flash disk assembly, the indicator lamp in the USB flash disk assembly is in a (full-on or full-off) state. That is, when the data read and write operations are small, the indicator light may flash unstably, may flash steadily for a while, may be on or off for a while, and so on. Therefore, before receiving the upgrade program in the usb disk assembly through the communication link, as a preference, the embedded system performs a pre-read operation to the usb disk assembly, where a specific flow of the pre-read operation includes: and executing a pre-reading operation on the U disk assembly, opening the U disk assembly, reading the capacity of the U disk assembly, calculating the maximum LBA address MAX-LBA in the U disk assembly, randomly selecting 1 LBA sector address between [ 0-MAX-LBA-1 ], judging whether the accumulated reading number exceeds 2Mbytes or not, if yes, completing the pre-reading operation, and if not, reproducing and returning to the previous step.

The embedded system reads and writes data of the USB flash disk assembly, and the corresponding indicator lights flash prompts; when the data reading and writing operation is not performed on the USB flash disk assembly, the corresponding indicator lamp is in a (full-on or full-off) state and is only one mode which can be realized, but the application is not limited and can be set by the user according to the needs of the user.
Before receiving an upgrade program imported by the USB flash disk assembly, the embedded system continuously and stably executes the pre-reading operation on the USB flash disk assembly for ensuring the stability of the reading operation and the corresponding flickering stability of the indicator lamp, and after the size of bytes of data to be read meets a certain condition, the pre-reading operation and the corresponding flickering stability of the indicator lamp are judged, so that a foundation is laid for the subsequent upgrade state information importing and displaying.
On the basis of the foregoing embodiment, as a preferred embodiment, a corresponding reading operation is performed on the usb disk assembly according to the upgrade status, so that the indicator light in the usb disk assembly displays a display status corresponding to the reading operation, including:
when the upgrade state is the first upgrade state;

Similarly, on the basis of the above embodiment, as a preferred embodiment, when the upgrade state is the third upgrade state;
and executing corresponding third reading operation on the USB flash disk assembly so that the indicator lamp in the USB flash disk assembly intermittently flashes according to the target time interval.
In a specific embodiment, a corresponding read operation is performed on the usb disk assembly according to the upgrade status, that is, the embedded system continuously reads the random LBA sector address from the usb disk assembly, where the number of bytes of the LBA sector address is 512 bytes. As shown in the table one, the upgrade states of the embedded device are classified into three types, the first type is upgrade success, the second type is non-execution upgrade behavior, the third type is upgrade failure, and the upgrade states corresponding to the upgrade failure are classified into a first upgrade state, a second state upgrade and a third upgrade state; the first upgrade state corresponds to a first reading operation, namely continuous reading, and the first indicator lamp control instruction corresponding to the first reading operation continuously flashes according to the target flashing frequency, namely continuous high-frequency flashing, so that the first upgrade state (successful upgrade) is displayed; the second reading operation corresponding to the second upgrading state, namely, not reading and writing, wherein the second indicator lamp control instruction corresponding to the second reading operation is continuously normally on or normally off according to the normally on or normally off requirement of the target, so that the second upgrading state is displayed (upgrading behavior is not executed); and the third reading operation corresponding to the third upgrading state, namely intermittent reading, and the third indicator lamp control instruction corresponding to the third reading operation is intermittently flashing according to the target time interval, so that the third upgrading state (upgrading failure) is displayed.
