160x128 TFT LCD at a claimed 18bit depth. Appears to be the Renesas HD66789R?, as used in iriver h300 and other Rockbox-supported devices.
SDRAM - K4M28163PH?
NOTE: Port is not ready for everyday use
The iAudio7 uses the standard Telechips firmware format - see TelechipsInfo
LW052A? is used to switch between radio and audio. Radio seems to be connected to 1Y0, 2Y0. That means codec is connected to 1Y1, 2Y1 as B pin is always low, and GPIOD0 is connected to A. INH pin is grounded.
The iAudio7 has a USB boot mode, you can enter it by holding down the 'mode' button while plugging in the USB connector. The Vendor/Product id changes to a TCC specific pair (Vendor=140e ProdID=b021), it is then possible to upload code to the device via tcctool (source available in svn tree: http://svn.rockbox.org/viewvc.cgi/trunk/utils/tcctool/ ).
The OF does the flashing, so a bad flash will ruin the player until we figure out how to do the USB boot mode properly.
