Ethos v1.5.7 and X18, X20 series User Manual
Logs/
Data logs are stored here.
models/
The radio stores model files here. These files cannot be edited by the user, but may be
backed up or shared from here. Initially models were simply named from model01.bin
onwards, but from Ethos v1.2.11 the model name is used, for example a model named
‘Extra’ will have a filename of ‘Extra.bin’. If there is more than one ‘Extra’, the additional
models will be named ‘Extra01.bin’ etc.
When editing the model names in the ‘Edit model’ screen the model filename (.bin) will
be changed too. The model filename will be in all lower case (the actual model name with
upper and lower case is saved inside the bin). Not all characters are supported for the
model file bin name so it might not match the model name exactly.
Starting with v1.1.0 Alpha 17 there are Sub Folders for each user created model category
folder.
screenshots/
Screenshots created by the Screenshot special function are stored here. Refer to the
Model / Special Functions section.
scripts/
This folder is used to store Lua scripts. Scripts may be organized into individual folders.
Please note that Lua scripts increase the startup time of the radio. If they are
implemented correctly the delay should not be noticeable, but if it is not the case, then
the delay may be almost indefinite.
scripts for external modules
Each third-party external module has its own individual Lua file, and should be stored
in its own folder.
scripts/multi
scripts/elrs
scripts/ghost
scripts/crossfire
Please refer to the Third-Party External Modules post on the X20 and Ethos thread on
rcgroups for more information.
radio.bin
This file is in the root folder and is created by the radio system when it initializes and
holds the system settings. It should be backed up together with the models folder above
before updating the firmware, to allow downgrading to the earlier version if required.
The firmware update file firmware.bin should be saved here in the root folder of the SD
card or eMMC when doing a radio firmware update. After saving the new firmware.bin
file, the update will automatically be flashed into the radio when it is disconnected from
the PC. (Please note that you also may need to update the SD card or eMMC and radio
flash drive contents at the same time.)
