It comes in 2/4/8/16GB sizes, and there is also a version with DAB digital radio. There is also an updated model known as the D2+, which features an updated case design and new firmware featuring BBE+ audio processing.

Hardware • CPU - Telechips TCC7801 - see • LCD module - Samsung - contains the S6F2002 LCD controller IC • Audio codec - Wolfson • RAM: Samsung K4M56323PG 32MB • NAND flash: Samsung (2GB) • PMU: Philips. • FM: Sanyo • Charger: Maxim • DAB: Telechips • Touchscreen Controller: Texas Instruments (newer D2+ revisions only) Disassembly and pictures at. Port Status The D2 port status is: unstable (see ) Most Rockbox functions are usable on the D2/D2+, including music playback and most plugins, but there are a number of shortcomings that prevent it from being a fully supported target: • An SD card is required to use many features, since the internal flash memory is read-only in Rockbox. • There is only basic touchscreen support. Rockbox runs on all D2 and D2+ variants (2 / 4 / 8 / 16GB, with or without DAB/DMB).

Using both USB and power adapter simultaneously may damage COWON D2+ - If you are using COWON D2+ for the first time or after using it for an extended period time, allow it to charge for sufficient amount of period.

NOTE: Newer D2+ hardware revisions use an updated power management chip, and some functionality is not yet implemented on these players (eg. Touchscreen support). The touchscreen can be used in two modes, either a 3x3 grid mode which divides the screen into areas to emulate a set of physical buttons (the default setting), or 'absolute point' mode where the touchscreen is used to point to items on the screen. Further work is required to make the UI more usable with a touchscreen in general. WARNING: The SD driver is still in development and may contain bugs. There have been reports of SD cards becoming unusable after being used with Rockbox on the D2.

Only using risk old, low-capacity SD cards until we are satisfied the driver is safe to use. You have been warned! Installation The Rockbox bootloader needs to be patched into an original Cowon firmware, which is then flashed to the D2 using the normal firmware upgrade process. This provides a dual-boot mechanism between Rockbox and the Cowon firmware (to boot Rockbox, set the HOLD switch immediately after power on). You will need a copy of your current Cowon firmware, ie.

The D2(N).bin file from the '1' folder in an official firmware update archive (these can be downloaded from ). NOTE: The filename depends on the firmware version as shown in the table below: D2 D2+ FW 1.xx / 4.xx D2.bin D2_P.bin FW 2.xx / 3.xx D2N.bin D2N _P.bin Automatic Installation The current release of Rockbox Installation Utility doesn't support the D2. Preliminary support is in SVN, and you can try binaries from SVN.

See for details. The utility should be able to detect and install Rockbox on your player. For more info visit the utility's. Manual Installation • Build or the bootloader binary (bootloader-cowond2.bin) • Patch this into your original Cowon firmware using mktccboot •./tools/mktccboot path_to_firmware/1/D2N.bin bootloader-cowond2.bin D2N-patched.bin • Build or download the main Rockbox build (rockbox.zip) • A pre-built 'bleeding edge' zip can be found. • Unzip rockbox.zip to the root of either an SD card or the internal memory • If an SD card is inserted at power on, Rockbox will boot from that card and use it as the primary drive for storing settings, etc. • If there is no SD card inserted, Rockbox will boot from the internal memory, and it will not be possible to save settings etc. The D2N-patched.bin can then either be uploaded to the player using tcctool (remember to set the HOLD switch as this is a dual-boot image), or flashed to the player using the usual firmware upgrade method.
