Yes, I meant to run it from the command line. You obviously need to make sure that you're in the right folder (i.e. the one containing the axf-file for the project you want to convert), and that the fromelf tool is actually located where it's supposed to be.

When you say it doesn't work, do you have any error messages or similar?

The nRF Loader can open files from other apps (e-mail, dropbox or similar) but only raw binary files, not hex files. To convert a hex or axf to binary, you can use for example the fromelf tool in C:\Keil\ARM\BIN40:


C:\Keil\ARM\BIN40\fromelf.exe ble_app_hrs.axf --output ble_app_hrs.bin --bin

After this, you can for example upload this binary file to your Dropbox or e-mail it to yourself, and then open the binary with nRF Loader to upload it to your development kit.
