}nvram_lid_commapp_enum;

Note: our new LID must between the ?NVRAM_EF_ADC_LID‘ and ?NVRAM_EF_LAST_LID_COMMAPP‘.

2.

Define size and total in

\\custom\\common\\PLUTO_MMI\\common_nvram_editor_data_item.h

code example:

#define NVRAM_EF_MIIPTS_MSG_SIZE 260 #define NVRAM_EF_MIIPTS_MSG_TOTAL 20

Note: size must be even, if not, phone will be reset just after power on.

3. Add version number to \\interface\\ps\\nvram_editor_data_item.h

code example:

#define NVRAM_EF_MIIPTS_MSG_LID_VERNO \

4. Add a new struct to logical_data_item_table_comm_app in

\\custom\\common\\PLUTO_MMI\\nvram_common_config.c

code example:

ltable_entry_struct

logical_data_item_table_comm_app[NVRAM_EF_LAST_LID_COMMAPP

NVRAM_LID_COMMAPP_BEGIN] = { , }

… { },

NVRAM_EF_MIIPTS_MSG_LID, NVRAM_EF_MIIPTS_MSG_SIZE, NVRAM_EF_MIIPTS_MSG_TOTAL, NVRAM_EF_ZERO_DEFAULT,

NVRAM_ATTR_AVERAGE,

NVRAM_CATEGORY_USER | NVRAM_CATEGORY_CUSTPACK, \

VER(NVRAM_EF_MIIPTS_MSG_LID), \

NVRAM_INVALID_VALUE

-

Note: this item positon is according to the ?NVRAM_EF_MIIPTS_MSG_LID‘ in the enum

存储这种数据，还可以使用系统内置的Flash，在MTK6225-07B-0812上，该盘符是Z盘。

fs_quota.c

在数组gFS_ExtQuotaSet中申请一项：

{\ FS_QP_HIG_ENUM, 10*1024, FS_QMAX_NO_LIMIT, FS_COUNT_IN_BYTE}

4.1

添加nvram项

在这个文件中添加nvram_user_config.c

4.2 Data structure:

typedef struct

{

S8 title[MIIPTS_MAXIMUM_MESSAGE_TITLE]; }miipts_struct_message_title;

typedef struct {

S8 title[MIIPTS_MAXIMUM_MESSAGE_TITLE]; S8 body[MIIPTS_MAXIMUM_MESSAGE_BODY]; }miipts_struct_message_item;

typedef struct

{

miipts_struct_message_title titles[MIIPTS_MAXIMUM_MESSAGE_ITEMS]; }miipts_struct_message_title_list;

4.3 Function

S32 miipts_read_msg_title_list(miipts_struct_message_title_list *list, S32 size); void miipts_read_msg(S32 index, miipts_struct_message_item *item); void miipts_write_msg(S32 index, miipts_struct_message_item *item); void miipts_append_msg(miipts_struct_message_item *item); void miipts_del_msg(S32 index);

4.4 note

We just read all the titles of messages into list when we browse the message list, but not all the message bodies because the data size may too large.

We read one message body into RAM when we enter the message body screen.
