Abstract

The embodiment of the invention discloses an information sending and firmware upgrading method, device, terminal and equipment and a storage medium. The firmware upgrading method includes the steps that a bootloader receives forced updated signals and judges whether the forced updated signals are effective or not, when the terminal detects damage of application firmware operation, a signal transmitting device is controlled to send signals namely the forced updating signals; if yes, the bootloader receives the command that the application firmware skips to the bootloader, and whether the request of updating the application firmware is received or not is detected; if yes, the bootloader receives the updating package of the application firmware, and updates the application firmware according to the updating package. The embodiment can solve the problem that the application firmware cannot be upgraded due to damage.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to information sending and firmware upgrading methods, devices, terminals, equipment and storage media. Background technique [0002] Firmware (Firmware) is a program stored in Eraseable Read Only Memory (EROM for short) or Erasable Programmable Read Only Memory (EPROM for short). The popular understanding is " hardened software". Firmware acts as the software for the most basic and bottom-level work of a system. In hardware devices, firmware is the soul of hardware devices, because some hardware devices have no other software components except firmware, so firmware also determines the function and performance of hardware devices. Wherein, firmware may also be referred to as application firmware. [0003] Firmware upgrade, sometimes called firmware refresh, shoe flashing, rewriting, burning or flashing, refers to the process of writing new firmware into the erasable p...
