102. Entering a bootloader program according to the starting state of the mainboard;
because the Bootloader is the first section of program executed by the embedded system after power-on, after the Bootloader completes the initialization of the CPU and the related hardware, the operating system image or the solidified embedded application program is loaded into the memory, and then the operating system jumps to the space where the operating system is located, and the operating system is started to run. Therefore, when the boot state of the mainboard is detected as boot, the bootloader program is entered and executed.
103. Acquiring an attribute value of the reliability write attribute of the eMMC by executing a verification function through a bootloader program, and judging whether the attribute value is equal to a preset value or not; if yes, go to step 104; if not, go to step 105;
