List of Checksum_Gen Tool errors & their solutions

Below is a list of Checksum_Gen Tool errors and how to resolve them

Checksum gen tool seems to be taking forever

Meaning: The checksum_gen tool is an old version, lacks the ability to process very large firmware files

Solution:

• Use a different version of checksum_gen tool @ (v5.1724 or above is recommended)

There are 2 files with filter "recovery.img"

Meaning: The checksum_gen tool has detected two files having similar filenames containing "recovery.img"

Solution:

• Remove the file ramdisk-recovery.img from within your firmware folder then re-generate checksum

Error 1017

Message: S_FILEPATH_NOT_SPECIFIED_YET(1017)!

Meaning: The checksum_gen tool is unable to find the file(s) specified within the scatter file

Solution:

• Ensure that you place all firmware files in the same folder as the scatter file

Error 1018

Message: S_UNKNOWN_TARGET_BBCHIP(1018)!

Meaning: The checksum_gen tool is not aware of the chipset of the scatter file

Solution:

• Retry using the latest version of checksum gen tool
• Edit the scatter file using any text editor such as Notepad++ then change the value for platform to the value below then save and generate checksum. Note that you will need to undo the change you made to the scatter file after successfully generating the checksum.ini file e.g if your scatter file was originally MT6765 then you must change MT6739 back to MT6765 after successfully generating checksum.ini
  platform: MT6739

Error 5078

Message: S_DL_BL_SIG_TYPE_UNSUPPORTED(5078)!

Meaning: The checksum_gen tool doesn't support the chipset of the scatter file. It must be a relatively new chipset type

Solution:

• Retry using the latest version of checksum gen tool
• Edit the scatter file using any text editor such as Notepad++ then change the value for platform to the value below then save and generate checksum. Note that you will need to undo the change you made to the scatter file after successfully generating the checksum.ini file e.g if your scatter file was originally MT6765 then you must change MT6739 back to MT6765 after successfully generating checksum.ini
  platform: MT6739

Error 5079

Message: S_DL_SCAT_VERSION_UNSUPPORTED(5079)!

Meaning: The checksum_gen tool doesn't support the scatter file's version

Solution:

• Edit the scatter file using any text editor such as Notepad++ then change the value for config_version to the value below then save and generate checksum. It's not compulsory to undo the change to scatter file as SP flash tool is able to work with scatter file v1.1.2 (you can undo the change to scatter file if you wish)
  config_version: V1.1.2
