Card (v2.7.0 onward) Card (v2.7.0 onward)
The process for updating firmware is further simplified on ATevo chargers supplied with
firmware v2.7.0 onward. Improvements that are discussed below include:
• Firmware updates are supplied as a single firmware file rather than individual files.
• Firmware filename can be unique as opposed to a fixed name.
• Usability Improvements:
◦ Update screens no longer reappear after firmware update is complete, as they did in
prior firmware versions.
◦ Users are prompted to return jumper JP4 to "NORM" when the update is complete.

To learn about the enhanced features that firmware v2.7.0 has brought to the
ATevo, see Appendix topic, Firmware v2.7.0 Enhancements.
Update With a Single File Update With a Single File
Firmware updates are now supplied as a single file. In firmware prior to v2.7.0 there were 2
files, mainapp.bin and bruno.bin to update the main processor and ui processor respectively.
These files are now packed into a single file.
File Name Convention File Name Convention
Firmware update files can now have a unique name which makes it possible to store multiple
firmware update files on an SD card. Firmware files are named to indicate the firmware version
contained in the file. The output file is still in 8.3 format (not a long filename). Firmware files
distributed for release will employ a file name that uses the following convention:
xxMMNNBB.hpb xxMMNNBB.hpb
In this convention, xx is "ev" for ATevo. MMNNBB represents the version where MM is the major
version, NN the minor version and BB build (i.e., minor minor version). The version numbers
are padded with a leading 0 for consistency. The extension "hpb" is an acronym for Hindle
Power Binary.
Here are some firmware filename examples that use this convention:
