简介： android10.0(Q) Nvram 新增节点

第一步：nvram lib数据结构定义


vendor\mediatek\proprietary\custom\k71v1_64_bsp\cgen\cfgfileinc\CFG_LOGO_File.h

//cczheng add for logo nvram start 
#ifndef _CFG_LOGO_FILE_H
#define _CFG_LOGO_FILE_H
typedef struct
{
    unsigned char Array[1024];
}LOGOINDEX_CUSTOM_PARAM_STRUCT;
#define CFG_FILE_LOGO_INDEX_REC_SIZE    sizeof(LOGOINDEX_CUSTOM_PARAM_STRUCT)
#define CFG_FILE_LOGO_INDEX_REC_TOTAL   1
//end
#endif

第二步：nvram lib 默认值定义


vendor\mediatek\proprietary\custom\k71v1_64_bsp\cgen\cfgdefault\CFG_LOGO_Default.h

//cczheng add for logo nvram start 
#ifndef _CFG_LOGO_DEFAULT_FILE_H
#define _CFG_LOGO_DEFAULT_FILE_H
#include "../cfgfileinc/CFG_LOGO_File.h"
LOGOINDEX_CUSTOM_PARAM_STRUCT stLogoDefault =
{
    0x01,0x00,0x00,0x00,0x0,0x0,0x0,0x0
};//end
#endif

第三步：nvram lib id定义


这里的添加节点顺序很关键，需要一一对应，在 AP_CFG_CUSTOM_FILE_MAX_LID 之前添加


vendor\mediatek\proprietary\custom\k71v1_64_bsp\cgen\inc\Custom_NvRam_LID.h

typedef enum
{
  ....
     AP_CFG_RDCL_FILE_AUDIO_FUNC_SWITCH_PARAM_LID,
     AP_CFG_CUSTOM_FILE_FUEL_GAUGE_LID,
     AP_CFG_CUSTOM_FILE_SMARTPA_CALIB_LID,
     AP_CFG_CUSTOM_FILE_LOGO_INDEX_LID,//cczheng add for logo nvram
     AP_CFG_CUSTOM_FILE_MAX_LID,
 } CUSTOM_CFG_FILE_LID;
/* smartpa calib version */
#define AP_CFG_CUSTOM_FILE_SMARTPA_CALIB_LID_VERNO    "000"
// cczheng add for logo nvram start 
#define AP_CFG_CUSTOM_FILE_LOGO_INDEX_LID_VERNO      "000"
 #endif /* CFG_FILE_LID_H */



第四步：nvram lib id的数据结构和版本号声明


需要和上面的位置对应，添加到最后


vendor\mediatek\proprietary\custom\k71v1_64_bsp\cgen\inc\Custom_NvRam_data_item.h

#ifndef CUSTOM_NVRAM_DATA_ITEM_H
#define CUSTOM_NVRAM_DATA_ITEM_H
#include "custom_cfg_module_file.h"
#include "Custom_NvRam_LID.h"
#include "../cfgfileinc/CFG_LOGO_File.h"
....
// cczheng add for logo nvram start 
LID_BIT VER_LID(AP_CFG_CUSTOM_FILE_LOGO_INDEX_LID)
LOGOINDEX_CUSTOM_PARAM_STRUCT *CFG_FILE_LOGO_INDEX_REC_TOTAL
{
};//end
END_NVRAM_DATA


第五步：nvram lib内容加入nvram数组中

vendor\mediatek\proprietary\custom\k71v1_64_bsp\cgen\inc\CFG_file_info_custom.h

//cczheng
#include "../cfgfileinc/CFG_LOGO_File.h"
#include "../cfgdefault/CFG_LOGO_Default.h"
   const TCFG_FILE g_akCFG_File_Custom[]=
   {
  ....
   { "/mnt/vendor/nvdata/APCFG/APRDCL/smartpa_calib", VER(AP_CFG_CUSTOM_FILE_SMARTPA_CALIB_LID), CFG_FILE_SMARTPA_CALIB_CONFIG_SIZE,
             CFG_FILE_SMARTPA_CALIB_CONFIG_TOTAL, SIGNLE_DEFUALT_REC, (char *)&smartpa_calib_ConfigDefault, DataReset, NULL
    },
     //cczheng add for logo nvram start 
    {
        "/mnt/vendor/nvdata/APCFG/APRDEB/LOGO_INDEX",  VER(AP_CFG_CUSTOM_FILE_LOGO_INDEX_LID),  CFG_FILE_LOGO_INDEX_REC_SIZE,
        // CFG_FILE_LOGO_INDEX_REC_TOTAL,   DEFAULT_ZERO,  0, DataReset, NULL
        CFG_FILE_LOGO_INDEX_REC_TOTAL,   SIGNLE_DEFUALT_REC,  (char *)&stLogoDefault, DataReset, NULL
    },//end
   };


第六步：nvram lib id需要备份到BinRegion

vendor\mediatek\proprietary\external\nvram\libcustom_nvram\CFG_file_info.c

FileName aBackupToBinRegion[] = {
  ...
  {"smartpa_calib", AP_CFG_CUSTOM_FILE_SMARTPA_CALIB_LID},
#endif
  {"LOGO_INDEX", AP_CFG_CUSTOM_FILE_LOGO_INDEX_LID},//cczheng add for logo nvram
 };
  ...
};
pfConvertFunc aNvRamConvertFuncTable[] = {
  ....
  NULL,//AP_CFG_RDEB_OMADM_USB_LID
  NULL,//AP_CFG_REEB_PRODUCT_INFO_LID
  NULL,//AP_CFG_CUSTOM_FILE_LOGO_INDEX_LID  cczheng add
  ...
};
const TABLE_FOR_SPECIAL_LID g_new_nvram_lid[] = {
#ifdef MTK_MLC_NAND_SUPPORT
  { AP_CFG_REEB_PRODUCT_INFO_LID, 0, 2 * 1024 * 1024 },
  { AP_CFG_CUSTOM_FILE_LOGO_INDEX_LID, 2 * 1024 * 1024, 1024 * 1024 },//cczheng add
#else
  { AP_CFG_REEB_PRODUCT_INFO_LID, 0, 1024 * 1024 },
  { AP_CFG_CUSTOM_FILE_LOGO_INDEX_LID, 1024 * 1024, 1024 * 1024 },//cczheng add
#endif
     ......
};

第七步：整编后烧写验证


adb shell

cd /mnt/vendor/nvdata/APCFG/APRDEB

可以看到 LOGO_INDEX

BT_Addr GPS LOGO_INDEX WIFI WIFI_CUSTOM

或者过滤日志

20201201 更新


采用上面的方式添加节点ID到 k71v1_64_bsp 项目名称中，后来遇到的问题


读取 nvram 数据正常，写入 nvram 数据时总是失败，错误日志如下


总是提示 write file error!


D/NVRAM: NVM_GetLIDByName /mnt/vendor/nvdata/APCFG/APRDEB/LOGO_INDEX

D/NVRAM: NVRAM: NVM_GetLIDByName Lid =62

D/NVRAM: 62 is in new nvram partition!!!

D/NVRAM: New NVRAM partition name is /dev/block/platform/bootdevice/by-name/proinfo.

D/NVRAM: RecNum is :1

D/NVRAM: write file error!

D/NVRAM: 62 is in new nvram partition!!!


解决办法

vendor\mediatek\proprietary\bootable\bootloader\lk\platform\mt6765\write_protect.c

注释里面的 set_write_protect(); 调用


  if (!bypass_wp) {
    //set_write_protect();
    pal_log_err("write protect Done! \n");
  } else
    pal_log_err("Bypass write protect! \n");


问题根本原因是正常开机情况下， product info 会被 EMMC 写保护挡下 power on write protect权限问题


可以继续优化 如何兼容开机客制化读写nvram 和 power on write protect feature.


通常做法是自行定义控制power on write protect对nvram 和product info 分区的开启和关闭。


如果不采用上面的添加节点方式，而是直接将节点添加到 vendor\mediatek\proprietary\custom\common 目录下，则不会出现写入失败的情况，但是会出现保存成功后回厂或者再次刷机保存数据会丢失。
