From 954b73265404075ec4d379ddea14e626113a8677 Mon Sep 17 00:00:00 2001 From: Miika Pekkarinen Date: Sat, 5 Aug 2006 20:19:10 +0000 Subject: [PATCH] Initial support and use for EEPROM memory on H120 & H140 players when Rockbox firmware has been flashed over original firmware (not yet possible to do). Dircache & tagcache serialization for fast bootup without the need to scan disk when Rockbox is in flash. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@10464 a1c6a512-1295-4272-9138-f99709370657 --- apps/debug_menu.c | 18 +++++ apps/main.c | 46 +++++++----- apps/misc.c | 25 ++++--- apps/tagcache.c | 109 +++++++++++++++++++++++++++- apps/tagcache.h | 2 + apps/tree.c | 9 ++- firmware/SOURCES | 4 ++ firmware/common/crc32.c | 4 +- firmware/common/dircache.c | 32 ++++++--- firmware/drivers/eeprom_24cxx.c | 6 +- firmware/eeprom_settings.c | 116 ++++++++++++++++++++++++++++++ firmware/export/config-h100.h | 6 +- firmware/export/config-h120.h | 10 ++- firmware/export/eeprom_settings.h | 48 +++++++++++++ firmware/export/system.h | 8 +++ firmware/include/crc32.h | 2 +- firmware/powermgmt.c | 4 +- firmware/system.c | 21 ++++++ 18 files changed, 422 insertions(+), 48 deletions(-) create mode 100644 firmware/eeprom_settings.c create mode 100644 firmware/export/eeprom_settings.h diff --git a/apps/debug_menu.c b/apps/debug_menu.c index 724bab90ab..ce3140be63 100644 --- a/apps/debug_menu.c +++ b/apps/debug_menu.c @@ -53,6 +53,8 @@ #include "tagcache.h" #include "lcd-remote.h" #include "crc32.h" +#include "eeprom_24cxx.h" +#include "logf.h" #ifdef HAVE_LCD_BITMAP #include "widgets.h" @@ -1952,6 +1954,22 @@ bool dbg_save_roms(void) close(fd); } system_memory_guard(oldmode); + +#ifdef HAVE_EEPROM + fd = creat("/internal_eeprom.bin", O_WRONLY); + if (fd >= 0) + { + char buf[EEPROM_SIZE]; + + if (!eeprom_24cxx_read(0, buf, sizeof buf)) + gui_syncsplash(HZ*3, true, "Eeprom read failure!"); + else + write(fd, buf, sizeof buf); + + close(fd); + } +#endif + return false; } #endif /* CPU */ diff --git a/apps/main.c b/apps/main.c index b725d0252f..907e1126cf 100644 --- a/apps/main.c +++ b/apps/main.c @@ -65,6 +65,7 @@ #include "lang.h" #include "string.h" #include "splash.h" +#include "eeprom_settings.h" #if (CONFIG_CODEC == SWCODEC) #include "playback.h" @@ -108,35 +109,30 @@ void app_main(void) browse_root(); } -#ifdef HAVE_DIRCACHE -void init_dircache(void) +int init_dircache(void) { - int result; - bool clear = false; +#ifdef HAVE_DIRCACHE + int result = 0; dircache_init(); if (global_settings.dircache) { - if (global_settings.dircache_size == 0) +# ifdef HAVE_EEPROM + if (firmware_settings.initialized && firmware_settings.disk_clean) { - gui_syncsplash(0, true, str(LANG_DIRCACHE_BUILDING)); - clear = true; + if (dircache_load(DIRCACHE_FILE) == 0) + return 0; } +# endif result = dircache_build(global_settings.dircache_size); - if (result < 0) - gui_syncsplash(0, true, "Failed!
