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/LinuxSimpleGuideToCompiling
The 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?
