From 4af2b4523b80ad63202aebb93b0b89d38e6a00dc Mon Sep 17 00:00:00 2001 From: jethead71 Date: Fri, 21 Jan 2011 07:05:51 +0000 Subject: [PATCH] Gigabeat S: Renovate bootloader a bit to show splash, implement verbose, shutdown on low battery, handle hold-switch-on and wait only so long for USB if a USB charger is inserted at boot instead of being connected to a host. 'Bootloader USB mode' display is just part of normal printf stream now. Move interrupt stacks into .bss area so they aren't loaded (for firmware too). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29099 a1c6a512-1295-4272-9138-f99709370657 --- bootloader/SOURCES | 1 + bootloader/common.c | 3 +- bootloader/gigabeat-s.c | 155 ++++++++++++++++++++------------------- firmware/target/arm/imx31/crt0.S | 10 ++- 4 files changed, 90 insertions(+), 79 deletions(-) diff --git a/bootloader/SOURCES b/bootloader/SOURCES index d16c51690..c56acb25b 100644 --- a/bootloader/SOURCES +++ b/bootloader/SOURCES @@ -8,6 +8,7 @@ ipod.c gigabeat.c #elif defined(GIGABEAT_S) gigabeat-s.c +show_logo.c ../firmware/target/arm/imx31/mmu-imx31.c #elif defined(IRIVER_H10) || defined(IRIVER_H10_5GB) || \ defined(SANSA_E200) || defined(SANSA_C200) || \ diff --git a/bootloader/common.c b/bootloader/common.c index 8c587edf5..8fb7cdef3 100644 --- a/bootloader/common.c +++ b/bootloader/common.c @@ -45,7 +45,8 @@ || defined(SAMSUNG_YH925) || defined(SAMSUNG_YH920) \ || defined(SAMSUNG_YH820) || defined(PHILIPS_SA9200) \ || defined(PHILIPS_HDD1630) || defined(PHILIPS_HDD6330) \ - || defined(ONDA_VX747) || defined(PBELL_VIBE500) + || defined(ONDA_VX747) || defined(PBELL_VIBE500) \ + || defined(TOSHIBA_GIGABEAT_S) bool verbose = false; #else bool verbose = true; diff --git a/bootloader/gigabeat-s.c b/bootloader/gigabeat-s.c index 77887f5d4..06f675644 100644 --- a/bootloader/gigabeat-s.c +++ b/bootloader/gigabeat-s.c @@ -30,6 +30,7 @@ #include "dir.h" #include "disk.h" #include "common.h" +#include "power.h" #include "backlight.h" #include "usb.h" #include "button.h" @@ -38,6 +39,9 @@ #include "usb-target.h" #include "version.h" +/* Show the Rockbox logo - in show_logo.c */ +extern int show_logo(void); + #define TAR_CHUNK 512 #define TAR_HEADER_SIZE 157 @@ -51,67 +55,44 @@ static void * const load_buf = 0x00000000; static const size_t load_buf_size = 0x20000000 - 0x100000; static const void * const start_addr = 0x00000000; -static void show_splash(int timeout, const char *msg) +/* Show a message + "Shutting down...", then power off the device */ +static void display_message_and_power_off(int timeout, const char *msg) { - backlight_on(); - reset_screen(); - lcd_putsxy( (LCD_WIDTH - (SYSFONT_WIDTH * strlen(msg))) / 2, - (LCD_HEIGHT - SYSFONT_HEIGHT) / 2, msg); - lcd_update(); - + verbose = true; + printf(msg); + printf("Shutting down..."); sleep(timeout); + power_off(); } -static bool pause_if_button_pressed(bool pre_usb) +static void check_battery_safe(void) { - while (1) - { - int button = button_read_device(); - - if (pre_usb && !usb_plugged()) - return false; - - /* Exit if no button or only select buttons that have other - * functions */ - switch (button) - { - case USB_BL_INSTALL_MODE_BTN: - if (!pre_usb) - break; /* Only before USB detect */ - case BUTTON_MENU: /* Settings reset */ - case BUTTON_NONE: /* Nothing pressed */ - return true; - } - - sleep(HZ/5); + if (battery_level_safe()) + return; - /* If the disk powers off, the firmware will lock at startup */ - storage_spin(); - } + display_message_and_power_off(HZ, "Battery low"); } /* TODO: Handle charging while connected */ -static void handle_usb(void) +static void handle_usb(int connect_timeout) { + long end_tick = 0; int button; - /* Check if plugged and pause to look at messages.
