I want to make some changes to apps/keymaps/keymap-e200.c so I can use UP and Down buttons to scroll. I followed this
http://www.rockbox.org/wiki/LinuxSimpleGuideToCompilingThe process was completed but my changes didn't work and looks like I will need some trials to get it working.
This one step in the document above:Now, type
cd rockbox/tools. Type
chmod +x rockboxdev.sh, then type
sudo ./rockboxdev.sh. You will be asked to choose the platform you want to compile for. If you are unsure, type s m a e i. This will prepare your computer to be able to build for all Rockbox targets. However, this will take much longer to prepare than a single platform, so if you know your target, just type the corresponding letter and continue.
Now my question is:
Do I have to follow the above step everytime after I make changes to keymap-e200.c or that is just needed once and then upon subsequent changes, I simply need to compile again and make zip?
I believe I just need to compile but want to double check. And what exactly the above step does?
