Detailed Description
At present, in the process of upgrading program firmware in a chip, if the chip is powered off or disconnected, boot of the chip may be suspended, and a system kernel cannot be booted normally to load, that is, the chip becomes a brick. In the face of the problem of chip brick changing, the chip can be disassembled at present, so that the disassembled chip is subjected to short circuit to enter an upgrading mode again, but the mode not only easily causes the chip to be damaged, but also greatly increases the labor cost; or, a design mode that the chip is shorted to enable the chip to enter an emergency download mode is considered during chip design, but the design mode may cause a product structure to need redesign, and may also bring potential safety hazards to user data in the product.
In view of the foregoing problems, an embodiment of the present invention provides a method for downloading a program firmware of a chip.
Fig. 1 is a flowchart of a method for downloading program firmware of a chip according to an embodiment of the present invention. Referring to fig. 1, the method for downloading the program firmware of the chip may include the following steps S102 to S110.
Step S102: and receiving a downloading instruction of the program firmware.
Step S104: and enabling the chip to enter a downloading mode according to the downloading instruction.
Step S106: download the agent (programmer).
Step S108: the boot loader firmware (bootloader) stored in the storage medium in the chip is erased by the agent program. In this step, the storage medium may be a flash memory (flash), but of course, the storage medium may also be other types of storage media.
Step S110: the boot program firmware is downloaded to the storage medium in the chip through the agent program.
In this embodiment, it is predetermined that if the storage medium of the chip is empty, the download mode can be directly entered. The manner of determining that the storage medium is empty may include: if the storage medium is not detected to have the boot program firmware, determining that the storage medium is empty; or, performing integrity check on the boot program firmware in the storage medium, and if the check fails, determining that the storage medium is empty. Specifically, the above-mentioned manner of determining that the storage medium is empty may be implemented by a boot loader (Bootrom Provider). The method comprises the steps of receiving a downloading instruction of program firmware, enabling a chip to enter a downloading mode according to the downloading instruction, downloading an agent program, erasing the boot program firmware stored in a storage medium in the chip through the agent program, downloading the boot program firmware to the storage medium in the chip through the agent program, and reentering the downloading mode no matter which step the downloading is interrupted, so that the problem that the chip is changed into bricks is avoided.
In an embodiment of the present invention, after erasing the boot program firmware stored in the storage medium in the chip by the agent program, the method may further include: the non-boot program firmware stored in the storage medium in the chip is erased by the agent program.

In this embodiment, the sequence of erasing the boot loader program firmware, erasing the non-boot loader program firmware, downloading the non-boot loader program firmware, and downloading the boot loader program firmware is adopted, so that the downloading mode can be re-entered no matter which step is interrupted, and the phenomenon that the chip is changed into a brick is avoided. Erasing only the boot program firmware stored in the storage medium can be understood as partial erasing, which is more efficient. After the boot program firmware stored in the storage medium is erased, the non-boot program firmware stored in the storage medium is also erased, which can be understood as total erasure, and compared with partial erasure, the total erasure can ensure that the non-boot program firmware can be updated every time of downloading, which is beneficial to maintaining the consistency of the versions of the non-boot program firmware and the boot program firmware.
In one embodiment of the invention, the non-boot program firmware may include, and is not limited to, the following:
application processor program firmware (ap), baseband chip plus coprocessor program firmware (cp), trusted zone program firmware (tz), non-volatile data program firmware (nv), and user data program firmware (userdata).
In one embodiment of the present invention, before erasing the boot program firmware stored in the storage medium in the chip by the agent, the method may include:
and backing up the program firmware stored in the storage medium in the chip.
In this embodiment, before erasing the boot program firmware stored in the storage medium in the chip by the agent program, the program firmware stored in the storage medium in the chip is backed up, so that the original program firmware can be prevented from being lost, thereby being beneficial to restoring the original program firmware.
In one embodiment of the present invention, after downloading the boot program firmware to the storage medium in the chip through the agent, the method may include: and restarting the chip. By restarting the chip, the downloaded program firmware can be validated.

Step S204: and enabling the chip to enter a downloading mode according to the downloading instruction.
Step S206: and downloading the agent program.
Step S208: and backing up the program firmware stored in the storage medium in the chip. In this step, the program firmware stored in the storage medium in the chip may be backed up by the agent program.
Step S210: the boot program firmware stored in the storage medium in the chip is erased by the agent program.
Step S212: the non-boot program firmware stored in the storage medium in the chip is erased by the agent program.
Step S214: the non-boot program firmware is downloaded to the storage medium via the agent program.
Step S216: the boot program firmware is downloaded to the storage medium in the chip through the agent program.
Step S218: and restarting the chip.
