This loader is needed to use Rockbox on iBasso DX50/DX90 devices. It replaces
/system/bin/MangoPlayer.
It expects
- the original firmware MangoPlayer as /system/bin/MangoPlayer_original
- the chooser.bmp file as /system/chooser.bmp
- the rbmissing.bmp file as /system/rbmissing.bmp
- the usb.bmp file as /system/usb.bmp
- Rockbox in /mnt/sdcard/.rockbox/ (internal device storage accessable via USB)
On first boot or if the device is booted with the hold switch engaged (upper,
locked position) this loader will let the user choose between Rockbox and the
orginal firmware MangoPlayer. It remembers the last choice and will start the
choosen player an following boots.
In the chooser screen
- the device can be powered off with a power button long press.
- Rockbox can be startet with the "Next/Fast Forward" button or by touching the
right part of the touchscreen.
- the orginal firmware MangoPlayer can be startet with the "Previous/Rewind"
button or by touching the left part of the touchscreen.
If Rockbox can not be found/executed than a "Rockbox is missing" screen will be
shown and the orginal firmware MangoPlayer will be started after 30 seconds.
This loader will (try to) restart Rockbox or the orginal firmware MangoPlayer if
something unexpected happens.
This loader can be installed via a customized firmware image (update.img) or
manually via the Android Debug Bridge (if you get adbd started on the device).
This is a rewrite and code clean up of the original submission, eliminating the
need for a custom Android Vold. This loader "knows", when Rockbox has exited due
to a USB mass storage connection remounting /mnt/sdcard and acts accordingly,
displaying a "USB connection" screen while waiting to restart Rockbox.

The port to for this two targets has been entirely developped by Ilia Sergachev (alias Il or xzcc). His source
can be found at https://bitbucket.org/isergachev/rockbox . The few necesary modifications for the DX90 port
was done by headwhacker form head-fi.org. Unfortunately i could not try out the final state of the DX90 port.
The port is hosted on android (without java) as standalone app. The official Firmware is required to run this port.
Ilia did modify the source files for the "android" target in the rockbox source to make the DX port work. The work I did
was to separate the code for DX50 (&DX90) from the android target.
On this Target Ilia used source from tinyalsa from AOSP. I did not touch that part of the code because I do not understand it.
What else I changed from Ilias sources besides the separation from the target "android":
* removed a dirty hack to keep backlight off
* changed value battery meter to voltage battery meter
* made all plugins compile (named target as "standalone") and added keymaps
* i added the graphics for the manual but did not do anything else for the manual yet
* minor optimizations
known bugs:
* timers are slowed donw when playback is active (tinyalsa related?)
* some minor bugs
Things to do:
* The main prolem will be how to install the app correctly. A guy called DOC2008 added a CWM (by androtab.info) to the
official firmware and Ilia made a CWM installation script and a dualboot selector (rbutils/ibassoboot, build with
ndk-build). We will have to find a way to install rockbox in a proper way without breaking any copyrights.
Maybe ADB is an option but it is not enable with OF by default. Patching the OF is probably the way to go.
* All the wiki and manual
to build:
needed: android ndk installed, android sdk installed with additional build-tools 19.1.0 installed
./tools/configure
select iBasso DX50 or iBasso DX90
make -j apk
the content of rockbox.zip/.rockbox needs to be copied to /system/rockbox/app_rockbox/rockbox/ (rockbox app not needed)
the content of libs/armeabi to /system/rockbox/lib/ (rockbox app needed)
The boot selector is needed as /system/bin/MangoPlayer and the iBasso app as /system/bin/MangoPlayer_original. There
is also the "vold" file. The one from OF does not work with DX50 rockbox (DX90 works!?), the one from Ilia is necessary.
Until we have found a proper way to install it, it can only be installed following the instructions of Ilia on his
bitbucket page, using the CWM-OF and his installation script package.
