Abstract

A method, apparatus, device, and a storage medium for upgrading a vehicle-mounted Tbox, which relate to the technical field of vehicle-mounted Tbox. The method comprises: when using a BOOTLOADER1 module that is used to store a power-on initial code for power-on startup, a vehicle-mounted Tbox determines whether version upgrading needs to be carried out (S401); and when it is determined that version upgrading needs to be carried out, the vehicle-mounted Tbox sequentially carries out version upgrading on a BOOTLOADER2 module for storing control logic and a diagnostic protocol stack code and app module (S402).

First claim

The invention claimed is:

1. A method for upgrading a vehicle-mounted Tbox, comprising:
determining, by the vehicle-mounted Tbox, when using a BOOTLOADER 1 module that is used to store a power-on initial code for power-on startup, whether version upgrading needs to be carried out;
carrying out, by the vehicle-mounted Tbox, when it is determined that version upgrading needs to be carried out, sequentially version upgrading on a BOOTLOADER2 module for storing control logic and a diagnostic protocol stack code and an APP module, wherein the Tbox refers to a telematics box; and then
detecting, by the vehicle-mounted Tbox, when it is detected that upgrading fails, a position where upgrading fails and performing upgrading failure repairing according to the position where upgrading fails, comprising;
determining, by the vehicle-mounted Tbox, by reading a state of GPIO1 and GPIO2, whether the position where upgrading fails is located in the BOOTLOADER2 module or the APP module;
carrying out, by the vehicle-mounted Tbox, when it is determined that the position where upgrading fails is located in the BOOTLOADER2 module, sequentially version upgrading on the BOOTLOADER2 module and the APP module; and
carrying out, by the vehicle-mounted Tbox, when it is determined that the position where upgrading fails is located in the APP module, version upgrading on the APP module,
wherein the GPIO1 refers to general purpose input/output 1, and the GPIO2 refers to general purpose input/output 2.

2. The method according to claim 1 , wherein after carrying out, by the vehicle-mounted Tbox, version upgrading on the BOOTLOADER 2 module and the APP module, the method further comprises:
detecting, by the vehicle-mounted Tbox, whether upgrading succeeds.

3. The method according to claim 1 , wherein determining, by the vehicle-mounted Tbox, by reading a state of GPIO1 and GPIO2, whether the position where upgrading fails is located in the BOOTLOADER2 module or the APP module comprises:
determining, by the vehicle-mounted Tbox, when the state of the GPIO1 and the GPIO2 is (0, 1), that the position where upgrading fails is located in the BOOTLOADER 2 module, and determining, by the vehicle-mounted Tbox, when the state of the GPIO1 and the GPIO2 is (1, 0), that the position where upgrading fails is located in the APP module; or
determining, by the vehicle-mounted Tbox, when the state of the GPIO1 and the GPIO2 is (1, 0), that the position where upgrading fails is located in the BOOTLOADER2 module, and determining, by the vehicle-mounted Tbox, when the state of the GPIO1 and the GPIO2 is (0, 1), that the position where upgrading fails is located in the APP module.

4. An apparatus for upgrading a vehicle-mounted Tbox, comprising:
a determining module, for determining whether version upgrading needs to be carried out when a BOOTLOADER1 module that is used to store a power-on initial code is used for power-on startup;
an upgrading module, for sequentially carrying out version upgrading on a BOOTLOADER2 module for storing control logic and a diagnostic protocol stack code and an APP module when it is determined that version upgrading needs to be carried out,
wherein the Tbox refers to a telematics box.; and
an upgrading failure repairing module for detecting a position where upgrading fails and performing upgrading failure repairing according to the position where upgrading fails when it is detected that upgrading fails, wherein the upgrading failure repairing module comprises;
a determining unit for determining, by reading a state of GPIO1 and GPIO2, whether the position where upgrading fails is located in the BOOTLOADER2 module or the APP module; and
an upgrading failure repairing unit for sequentially carrying out version upgrading on the BOOTLOADER2 module and the APP module when it is determined that the position where upgrading fails is located in the BOOTLOADER2 module, and carrying out version upgrading on the APP module when it is determined that the position where upgrading fails is located in the APP module,
wherein the GPIO1 refers to general purpose input/output 1, and the GPIO2 refers to general purpose input/output 2.

5. The apparatus according to claim 4 , wherein the upgrading failure repairing module detects whether upgrading succeeds.

6. The apparatus according to claim 4 , wherein the determining unit is used to determine that the position where upgrading fails is located in the BOOTLOADER2 module when the state of the GPIO1 and the GPIO2 is (0, 1), and the vehicle-mounted Tbox determines that the position where upgrading fails is located in the APP module when the state of the GPIO1 and the GPIO2 is (1, 0); or the determining unit is used to determine that the position where upgrading fails is located in the BOOTLOADER2 module when the state of the GPIO1 and the GPIO2 is (1, 0), and the vehicle-mounted Tbox determines that the position where upgrading fails is located in the APP module when the state of the GPIO1 and the GPIO2 is (0, 1).

7. A device for upgrading a vehicle-mounted Tbox, wherein the device comprises a processor and a memory coupled to the processor, wherein the memory stores programs for upgrading a vehicle-mounted Tbox that can be run on the processor, and the programs for upgrading a vehicle-mounted Tbox, when executed by the processor, implement steps of the method for upgrading a vehicle-mounted Tbox according to claim 1 .
