From 28f6ae49ec1b1d3464add2941eb015bab56f8016 Mon Sep 17 00:00:00 2001 From: Dave Chapman Date: Sun, 28 Oct 2007 11:08:10 +0000 Subject: Initial work on a port to the Logik DAX 1GB MP3/DAB player. The bootloader build compiles and runs (but only displays some debugging info), and the LCD and ADC drivers are working. Two different bootloader builds are possible: 1) The default build is just a test application for uploading to the device via tcctool; 2) Adding -DTCCBOOT to EXTRA_DEFINES in the build directory Makefile will compile the bootloader so that it can be appended to the end of the original firmware and installed on the device, dual-booting. This commit also includes some work by Hein-Pieter van Braam on a port to the iAudio 7, but that doesn't build yet. A large part of these ports will be generic to all TCC77x devices - see the TelechipsInfo wiki page for some other devices with this CPU. NOTE: Compiling these builds requires an arm-elf-gcc with armv5 support - the current version of rockboxdev.sh compiles such a gcc. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15339 a1c6a512-1295-4272-9138-f99709370657 --- firmware/FILES | 2 + firmware/SOURCES | 23 +- firmware/boot.lds | 57 ++++- firmware/export/config-logikdax.h | 107 +++++++++ firmware/export/config.h | 21 +- firmware/export/cpu.h | 3 + firmware/export/tcc77x.h | 81 +++++++ firmware/target/arm/tcc77x/adc-tcc77x.c | 71 ++++++ firmware/target/arm/tcc77x/ata-nand-tcc77x.c | 94 ++++++++ firmware/target/arm/tcc77x/ata-target.h | 22 ++ firmware/target/arm/tcc77x/crt0.S | 153 +++++++++++++ firmware/target/arm/tcc77x/logikdax/adc-target.h | 26 +++ .../target/arm/tcc77x/logikdax/backlight-target.h | 38 ++++ .../target/arm/tcc77x/logikdax/button-target.h | 70 ++++++ firmware/target/arm/tcc77x/logikdax/lcd-logikdax.c | 253 +++++++++++++++++++++ .../target/arm/tcc77x/logikdax/power-logikdax.c | 66 ++++++ firmware/target/arm/tcc77x/system-target.h | 35 +++ firmware/target/arm/tcc77x/system-tcc77x.c | 136 +++++++++++ firmware/thread.c | 5 + 19 files changed, 1260 insertions(+), 3 deletions(-) create mode 100644 firmware/export/config-logikdax.h create mode 100644 firmware/export/tcc77x.h create mode 100644 firmware/target/arm/tcc77x/adc-tcc77x.c create mode 100644 firmware/target/arm/tcc77x/ata-nand-tcc77x.c create mode 100644 firmware/target/arm/tcc77x/ata-target.h create mode 100644 firmware/target/arm/tcc77x/crt0.S create mode 100644 firmware/target/arm/tcc77x/logikdax/adc-target.h create mode 100644 firmware/target/arm/tcc77x/logikdax/backlight-target.h create mode 100644 firmware/target/arm/tcc77x/logikdax/button-target.h create mode 100644 firmware/target/arm/tcc77x/logikdax/lcd-logikdax.c create mode 100644 firmware/target/arm/tcc77x/logikdax/power-logikdax.c create mode 100644 firmware/target/arm/tcc77x/system-target.h create mode 100644 firmware/target/arm/tcc77x/system-tcc77x.c (limited to 'firmware') diff --git a/firmware/FILES b/firmware/FILES index a3cfc0c8c2..1882f3dd07 100644 --- a/firmware/FILES +++ b/firmware/FILES @@ -25,6 +25,8 @@ target/arm/archos/av300/*.[chS] target/arm/s3c2440/gigabeat-fx/*.[chS] target/arm/iriver/*.[chS] target/arm/iriver/h10/*.[chS] +target/arm/tcc77x/*.[chS] +target/arm/tcc77x/logikdax/*.[chS] target/arm/tms320dm320/*.[chS] target/arm/tms320dm320/mrobe-500/*.[chS] target/arm/pnx0101/*.[chS] diff --git a/firmware/SOURCES b/firmware/SOURCES index 9e501b661a..5061ac7370 100644 --- a/firmware/SOURCES +++ b/firmware/SOURCES @@ -111,7 +111,7 @@ drivers/ata_mmc.c #ifdef HAVE_FLASH_DISK drivers/ata_flash.c #else /* !HAVE_FLASH_DISK */ -#if !defined(SANSA_E200) && !defined(SANSA_C200) +#if !defined(SANSA_E200) && !defined(SANSA_C200) && !defined(LOGIK_DAX) && !defined(IAUDIO_7) drivers/ata.c #endif /* SANSA_E200 */ #endif /* HAVE_FLASH_DISK */ @@ -336,6 +336,8 @@ target/arm/crt0-pp.S target/arm/pnx0101/crt0-pnx0101.S #elif defined(OLYMPUS_MROBE_500) target/arm/tms320dm320/crt0.S +#elif defined(CPU_TCC77X) +target/arm/tcc77x/crt0.S #elif defined(CPU_ARM) target/arm/crt0.S #endif /* defined(CPU_*) */ @@ -814,3 +816,22 @@ target/arm/pnx0101/pcm-pnx0101.c #endif /* SIMULATOR */ #endif /* IRIVER_IFP7XX */ +#ifdef LOGIK_DAX +#ifndef SIMULATOR +target/arm/tcc77x/adc-tcc77x.c +target/arm/tcc77x/ata-nand-tcc77x.c +target/arm/tcc77x/system-tcc77x.c +target/arm/tcc77x/logikdax/lcd-logikdax.c +target/arm/tcc77x/logikdax/power-logikdax.c +#endif /* SIMULATOR */ +#endif /* LOGIK_DAX */ + +#ifdef IAUDIO_7 +#ifndef SIMULATOR +target/arm/tcc77x/adc-tcc77x.c +target/arm/tcc77x/ata-nand-tcc77x.c +target/arm/tcc77x/system-tcc77x.c +target/arm/tcc77x/iaudio7/lcd-iaudio7.c +target/arm/tcc77x/iaudio7/power-iaudio7.c +#endif /* SIMULATOR */ +#endif /* IAUDIO_7 */ diff --git a/firmware/boot.lds b/firmware/boot.lds index a8404134ae..d2ea10a30d 100644 --- a/firmware/boot.lds +++ b/firmware/boot.lds @@ -11,6 +11,8 @@ OUTPUT_ARCH(arm) INPUT(target/arm/crt0-pp-bl.o) #elif defined(OLYMPUS_MROBE_500) INPUT(target/arm/tms320dm320/crt0.o) +#elif defined(CPU_TCC77X) +INPUT(target/arm/tcc77x/crt0.o) #else INPUT(target/arm/crt0.o) #endif @@ -77,6 +79,12 @@ INPUT(target/sh/crt0.o) #define IRAMSIZE 16K #define FLASHORIG 0x0000000 #define FLASHSIZE 1M +#elif defined(CPU_TCC77X) +#define DRAMORIG 0x20000000 +#define IRAMORIG 0x00000000 +#define IRAMSIZE 64K +#define FLASHORIG 0x0000000 +#define FLASHSIZE 1M #else #define DRAMORIG 0x09000000 #define IRAMORIG 0x0f000000 @@ -85,7 +93,17 @@ INPUT(target/sh/crt0.o) #define FLASHSIZE 256K -
