MG35Tool
MG35Tool (mg35tool) is a tool for splitting and combining .upgrade files for the MG-35 media player.
Version: 1.3
Status: Done
Description
mg35tool automatically removes all header information when splitting files and automatically recalculates it again when joining files.
This tool works on both Windows and Linux and this file contains both executables and source code.
Usage
mg35tool <split | join > [-v version] [-t model] [-b boot_file] [-k kernel_file] [-c cramfs_file] <upgrade_file>
Options:
-b boot_file
Specifies name of boot loader file. Default when splitting
is boot.rom. When joining, the BOOT section of the update
file is only included if this option is specified.
-k kernel_file
Specify a compressed kernel file. Default is |linux.gz|
-c cramfs_file
Specify a compressed filing system file. Default is |cramfs.img|.
-v
Specify the version of the .upgrade file in the format major.minor.patch
This information will be built into the upgrade file's header when
joining. This option has no effect when splitting.
-t { MG25 | MG35 | MG350HD | MG350SHD | AUTO }
Specify the Mediagate hardware model. Default is MG35 for join, AUTO for split.
Examples
mg35tool split MG35_1.4.3.upgrade
This will split the upgrade file and produce three files: boot.rom, linux.gz and cramfs.img
mg35tool join -k kernel.gz -c test.img MG35-test.upgrade
This will take kernel.gz and test.img and produce an upgrade file with a ROFS section but no BOOT section. All sizes and checksums will be calculated automatically as will the offset to the CramFS that is required to directly precede the kernel.
Note: .upgrade files without boot sections work very well on the MG-35 and are highly recommended!
