From d64e626387e21dc6a7ab374f17dec1e902cd9779 Mon Sep 17 00:00:00 2001 From: Dave Chapman Date: Sun, 14 Jan 2007 13:48:09 +0000 Subject: Start of work on a port to the Archos 'AV300' (AV320/340/380) - a working UI simulator (but with a dummy background image for now) and the beginnings of the target-specific firmare code. Port is temporarily using a 2bpp LCD buffer format - the AV300 has a 320x240 colour (YCbCr-based) LCD which will need a new framebuffer format and drawing routines, but the LCD is also capable of various paletted bitmap modes, one of which has an identical framebuffer format to the greyscale ipods. Buttons (and hence the button mappings) are identical to the Archos Recorder, with the exception that the PLAY button on the Recorder is replaced by pressing the joystick on the AV300 (which I call BUTTON_SELECT). The initial port will begin by being strictly HWCODEC, but will evolve to be a hybrid SWCODEC/HWCODEC platform - it has a MAS3587F but also a main CPU (54MHz arm7tdmi plus DSP) capable of software decoding of at least some formats. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12008 a1c6a512-1295-4272-9138-f99709370657 --- firmware/target/arm/archos/av300/ata-av300.c | 56 ++++++++++++++ firmware/target/arm/archos/av300/ata-target.h | 62 +++++++++++++++ firmware/target/arm/archos/av300/button-target.h | 49 ++++++++++++ firmware/target/arm/archos/av300/power-av300.c | 97 ++++++++++++++++++++++++ 4 files changed, 264 insertions(+) create mode 100644 firmware/target/arm/archos/av300/ata-av300.c create mode 100644 firmware/target/arm/archos/av300/ata-target.h create mode 100644 firmware/target/arm/archos/av300/button-target.h create mode 100644 firmware/target/arm/archos/av300/power-av300.c (limited to 'firmware/target/arm/archos') diff --git a/firmware/target/arm/archos/av300/ata-av300.c b/firmware/target/arm/archos/av300/ata-av300.c new file mode 100644 index 0000000000..ae7b955632 --- /dev/null +++ b/firmware/target/arm/archos/av300/ata-av300.c @@ -0,0 +1,56 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id: ata-pp5020.c 10521 2006-08-11 08:35:27Z bger $ + * + * Target-specific ATA functions for AV3xx (TMS320DSC25) + * + * Based on code from the ArchOpen project - http://www.archopen.org + * Adapted for Rockbox in January 2007 + * + * Original file: + * lib/target/arch_AV3XX/ata.c + * + * AvLo - linav project + * Copyright (c) 2005 by Christophe THOMAS (oxygen77 at free.fr) + * + * All files in this archive are subject to the GNU General Public License. + * See the file COPYING in the source tree root for full license agreement. + * + * This software is distributed on an "AS IS" basis, WITHOUT WARRANTY OF ANY + * KIND, either express or implied. + * + ****************************************************************************/ + +#include +#include "system.h" +#include "ata-target.h" + +void ata_reset() +{ + /* arch_ata_reset_HD(void) */ + cpld_set_port_2(CPLD_HD_RESET);
