this threat is reagarding to port rockbox to the meizu. the rockbox website is maybe a better place to post feature requests like this.

the devs are doing a great work, and it's definitly not the time to talk about such functionality. i guess most people don't know how much effort it costs to implement all the necassary drivers. the most important thing currently is to get something drawn on the display. and this is not easy, and the only way to get debug information ist to toggle the backlight.
i think we are all glad to get some news about the progress from time to time, so please don't bother them with things like this at this time.
