After the upgrade is completed, set the attribute of the hyper terminal to its initial settings.
Then, power off and reboot the router. Confirm whether the bootloader program is normally
upgraded through the xxx information of Bootloader 1.13 PR020_29 (Feb 22 2017 - 23:27:08)
In upgrading the bootloader program, ensure that the rate of the
HyperTerminal is the same as the rate of the device Console port.
In upgrading the bootloader program, the transmission speed is
recommended to be set to 115200 bps. In this way, the upgrade
transmission time is shorter.
If the default rate of the Console port has been modified in upgrading the
bootloader program, in loading the image program package, the rate of the
device Console port automatically resumes to 9600 bps. At this time, the
rate of the HyperTerminal needs to be modified synchronously.
It is recommended that you upgrade the bootloader program in TFTP/FTP
mode. The Console port is used to upgrade the monitor program only when
the upgrade conditions of the first upgrade mode fail to be satisfied.
During the upgrade process, the device must not be powered off or
restarted. Otherwise, the system may fail to start, or the monitor file of the
device may be damaged.
