MT6589 暗码更改开机LOGO
一。lk logo 修改
1. kernel\kernel\power\main.c （创建节点，控制logo切换状态）
#if 1//HIGUA
// for set_env() by MTK
#include <mach/env.h>
#endif
...
#if 1// HIGUA
ssize_t custom_changelogo_show(struct kobject *kobj,
struct kobj_attribute *attr,
char *buf)
{
char *val = NULL;
if(NULL != get_env("changelogo")){
val = get_env("changelogo");
}
return sprintf(buf, "%s\n", val);
}
/*---------------------------------------------------------------------------*/
ssize_t custom_changelogo_store(struct kobject *kobj, struct kobj_attribute *attr,
const char *buf, size_t n)
{
if(!strncmp(buf,"1",1))
{
set_env("changelogo", "1");
}
else if(!strncmp(buf,"0",1))
{
set_env("changelogo", "0");
}
return n;
}
static struct kobj_attribute custom_changelogo_attr = {
.attr = {
.name = "custom_changelogo",
.mode = 0777,
},
.show = custom_changelogo_show,
.store = custom_changelogo_store,
};
#endif
static struct attribute * g[] = {
...
#if 1// HIGUA
&custom_changelogo_attr.attr,
#endif
NULL,
}
2. MediaTek\platform\mt6589\lk\mt_logo.c （根据logo状态显示不同的logo）
//这里的 38 是 自定义logo的显示序号 在下面会介绍
void mt_disp_show_boot_logo(void)
{
...
#if 1//higua change logo
if(get_env("changelogo") != NULL && atoi(get_env("changelogo")) == 1){
show_logo(0);
}else{
show_logo(38);
}
#else
show_logo(0);
#endif
mt_disp_update(0, 0, CFG_DISPLAY_WIDTH, CFG_DISPLAY_HEIGHT);
...
}
3.mediatek\platform\mt6589\lk\platform.c (现在一进入recovey 就会设置 切换logo的属性，正常的应该是在恢复出厂设置的时候 )
void sw_env()
{
...
#if 1 // higua restore change logo
if(g_boot_mode == RECOVERY_BOOT){
set_env("changelogo","1");
}
#endif
#ifndef USER_BUILD
switch (g_boot_mode)
{
case META_BOOT:
...
}
4. mediatek\custom\common\lk\logo\rules.mk （添加 logo 图片）
上面用到的 38 序列号 就是 RESOURCE_OBJ_LIST 所有文件的顺序， 添加的logo 是第38个位置的图片
$(BOOT_LOGO_DIR)/$(BOOT_LOGO)/$(BOOT_LOGO)_bat_100.raw \
$(BOOT_LOGO_DIR)/$(BOOT_LOGO)/$(BOOT_LOGO)_normal_Uboot.raw \
$(BOOT_LOGO_DIR)/$(BOOT_LOGO)/$(BOOT_LOGO)_kernel.raw
还需要在 对应的 logo目录里添加一张BMP图片
例： 我们的工程是 cu_hd720 所以在 cu_hd720 文件夹下添加 一张 cu_hd720_normal_uboot.bmp 图片
mediatek\custom\common\lk\logo\cu_hd720\cu_hd720_normal_uboot.bmp
二。kernel logo 修改
1.mediatek\external\boot_logo_updater\boot_logo_updater.c （判断是否显示临时的logo文件）
int main(void)
{
...
// (3) open logo file
#if 1//higua
if ((fd = open("/data/mdl/local_boot_logo", O_RDONLY)) < 0) {
if ((fd = open(LOGO_PATH, O_RDONLY)) < 0) {
fprintf(stderr, "failed to open logo file: %s\n", LOGO_PATH);
goto done;
}
}
#else
if ((fd = open(LOGO_PATH, O_RDONLY)) < 0) {
fprintf(stderr, "failed to open logo file: %s\n", LOGO_PATH);
goto done;
}
#endif
// (4) map framebuffer
...
}
三。开机动画 修改
1.Frameworks\base\cmds\bootanimation\BootAnimation.cpp
status_t BootAnimation::readyToRun() {
...
if (bBootOrShutDown) {
status_t err = mZip.open("/data/local/bootanimation.zip");
XLOGD("[BootAnimation %s %d]err=%d,%s,/data/local/bootanimation.zip",__FUNCTION__,__LINE__,err,strerror(-err));
#if 1//higua
if (err != NO_ERROR) {
err = mZip.open("/data/mdl/bootanimation.zip");
XLOGD("[BootAnimation %s %d]err=%d,%s,/data/mdl/bootanimation.zip",__FUNCTION__,__LINE__,err,strerror(-err));
}
#endif
if (err != NO_ERROR) {
err = mZip.open("/system/media/bootanimation.zip");
XLOGD("[BootAnimation %s %d]err=%d,%s,/system/media/bootanimation.zip",__FUNCTION__,__LINE__,err,strerror(-err));
if (err != NO_ERROR) {
mAndroidAnimation = true;
}
}
} else {
if (!bShutRotate) {
status_t err = mZip.open("/data/local/shutanimation.zip");
XLOGD("[BootAnimation %s %d]err=%d,%s,/data/local/shutanimation.zip",__FUNCTION__,__LINE__,err,strerror(-err));
#if 1//higua
if (err != NO_ERROR) {
err = mZip.open("/data/mdl/shutanimation.zip");
XLOGD("[BootAnimation %s %d]err=%d,%s,/data/mdl/shutanimation.zip",__FUNCTION__,__LINE__,err,strerror(-err));
}
#endif
if (err != NO_ERROR) {
err = mZip.open("/system/media/shutanimation.zip");
XLOGD("[BootAnimation %s %d]err=%d,%s,/system/media/shutanimation.zip",__FUNCTION__,__LINE__,err,strerror(-err));
if (err != NO_ERROR) {
mAndroidAnimation = true;
}
}
} else {
status_t err = mZip.open("/data/local/shutrotate.zip");
...
}
四。快速开机修改
1.mediatek\external\ipod\bootlogo.cpp (之前没改到这里，启动快速开机 的时候 lk，kernel 都没生效，今天才解决这问题）
void mt65xx_boot_logo_updater_init(void)
{
...
// (3) open logo file
#if 1//higua
if ((fd = open("/data/mdl/local_boot_logo", O_RDONLY)) < 0) {
if ((fd = open(LOGO_PATH, O_RDONLY)) < 0) {
fprintf(stderr, "[ChargingAnimation]failed to open logo file: %s\n", LOGO_PATH);
goto done;
}
}
#else
if ((fd = open(LOGO_PATH, O_RDONLY)) < 0) {
fprintf(stderr, "[ChargingAnimation]failed to open logo file: %s\n", LOGO_PATH);
goto done;
}
#endif
// (5) copy the 2nd logo to surface info
...
}
...
#if 1//higua
static int custom_show_local_logo(void)
{
int fd = -1;
if ((fd = open("/data/mdl/local_boot_logo", O_RDONLY)) >= 0){
close(fd);
return 1;
}
return 0;
}
#endif
void mt65xx_disp_show_boot_logo(void)
{
XLOGD("[ChargingAnimation %s %d]index = 0 ,x_virtual=%d, vinfo.yres=%d \n",__FUNCTION__,__LINE__,x_virtual, vinfo.yres);
Region region(Rect(0, 0, x_virtual, vinfo.yres));
status_t lockResult = surface->lock(&info, ®ion);
XLOGD("[ChargingAnimation %s %d]info.bits = 0x%08x\n",__FUNCTION__,__LINE__, info.bits);
XLOGD("[ChargingAnimation %s %d]surface->lock return = 0x%08x, %d\n",__FUNCTION__,__LINE__,lockResult,lockResult);
if (0 == lockResult)
{
#if 1//higua
if(1 == custom_show_local_logo()){
show_logo_surface(38);
} else {
show_logo_surface(0);
}
#else
show_logo_surface(0);
#endif
surface->unlockAndPost();
}
return;
}
...
五。APP 见附件
boot_logo 开机logo
bootanimation.zip 开机动画
shutanimation.zip 关机动画
这三个文件 在编译后 会拷贝到 /data/mdl/ 目录，之所以拷到这里来，是因为这个目录是 0777 权限的。省了在手动更改权限的问题
