Flash is not erased when uploading hexfile

[ghost]

Using the Platformio IDE integrated in Atom, when performing "Upload" the command line output shows that the "-D" flags is used with the avrdude tool.

This disables auto erase for flash. However, it is essential that the flash is erased before uploading new code into it. I am using a bare Atmega48 (no Arduino). I did not find a way to remove this flag anywhere in the platformio config files..

Use program instead upload. See http://docs.platformio.org/en/latest/platforms/atmelavr.html#upload-using-programmer

program is bare target and you can customize it manually using upload_flags.

Great! Is it possible to have this integrated in the left toolbar? Otherwise I need to select "PlatformIO: Upload using programmer" either via left bottom option or via F7.

Em.... Very interesting question 👍 There are a lot of solutions to do it 😄

How about to create extra_script and override with custom upload command?

See my example here platformio/platformio-core#247 (comment)

Thanks for the fast reply. Honestly I want to avoid tinkering with scripts. So I will use the available option then.

Another option is to use targets. In this case, "Build" button will have "program" behaviour.

For example,

[env:my]
targets = program
