Usage for upgrade_tool

Command Line Mode

upgrade_tool is used in command line mode similar to rkdeveloptool.

In command line mode, upgrade_tool does not support the selection of a Maskrom device, nor can it select the storage media to be written to.

If you need to select a specific one from multiple devices, use interactive mode.

View connected Maskrom devices

./upgrade_tool ld

Write file

tip

upgrade_tool does not automatically decompress compressed files when writing to them.

First extract the used files and specify the extracted files in upgrade_tool.

sudo ./upgrade_tool db <loader>
sudo ./upgrade_tool wl 0 <image>

Download links for the required Loader and Image files can be found below.

Reboot device

sudo ./upgrade_tool rd

Interactive Mode

If upgrade_tool is executed without any arguments, it will automatically enter interactive mode.

This mode will first ask to select the device to be written to:

$ sudo ./upgrade_tool
Using /home/rock/Linux_Upgrade_Tool/config.ini
Program Log will save in the /root/upgrade_tool/log/

Parallel Write

Since upgrade_tool blocks the current terminal when writing to a device, if you need to write to multiple devices at the same time, you need to execute upgrade_tool multiple times to create multiple interactive mode sessions.
