Usage Guidelines

Usage Scenario

Boot Read-Only Memory (BootROM) is a set of programs added to the ROM chip of a device. BootROM saves the device's most important input and output programs, system settings, startup self-check program, and system automatic startup program.

When the system crashes and you cannot enter the command line interface, you can run this command in the BootROM menu. Then the system software is transmitted using the Xmodem protocol to recover or upgrade the system.


Ensure that the APP file is correct; otherwise, the device cannot start.
