首先在main.c中增加了
`
#if ((SPI_FLASH_SIZE_MAP == 0) || (SPI_FLASH_SIZE_MAP == 1))
#error "The flash map is not supported"
#elif (SPI_FLASH_SIZE_MAP == 2)
#define SYSTEM_PARTITION_OTA_SIZE 0x6A000
#define SYSTEM_PARTITION_OTA_2_ADDR 0x81000
#define SYSTEM_PARTITION_RF_CAL_ADDR 0xfb000
#define SYSTEM_PARTITION_PHY_DATA_ADDR 0xfc000
#define SYSTEM_PARTITION_SYSTEM_PARAMETER_ADDR 0xfd000
#define SYSTEM_PARTITION_CUSTOMER_PRIV_PARAM_ADDR 0x7c000
#elif (SPI_FLASH_SIZE_MAP == 3)
#define SYSTEM_PARTITION_OTA_SIZE 0x6A000
#define SYSTEM_PARTITION_OTA_2_ADDR 0x81000
#define SYSTEM_PARTITION_RF_CAL_ADDR 0x1fb000
#define SYSTEM_PARTITION_PHY_DATA_ADDR 0x1fc000
#define SYSTEM_PARTITION_SYSTEM_PARAMETER_ADDR 0x1fd000
#define SYSTEM_PARTITION_CUSTOMER_PRIV_PARAM_ADDR 0x7c000
#elif (SPI_FLASH_SIZE_MAP == 4)
#define SYSTEM_PARTITION_OTA_SIZE 0x6A000
#define SYSTEM_PARTITION_OTA_2_ADDR 0x81000
#define SYSTEM_PARTITION_RF_CAL_ADDR 0x3fb000
#define SYSTEM_PARTITION_PHY_DATA_ADDR 0x3fc000
#define SYSTEM_PARTITION_SYSTEM_PARAMETER_ADDR 0x3fd000
#define SYSTEM_PARTITION_CUSTOMER_PRIV_PARAM_ADDR 0x7c000
#elif (SPI_FLASH_SIZE_MAP == 5)
#define SYSTEM_PARTITION_OTA_SIZE 0x6A000
#define SYSTEM_PARTITION_OTA_2_ADDR 0x101000
#define SYSTEM_PARTITION_RF_CAL_ADDR 0x1fb000
#define SYSTEM_PARTITION_PHY_DATA_ADDR 0x1fc000
#define SYSTEM_PARTITION_SYSTEM_PARAMETER_ADDR 0x1fd000
#define SYSTEM_PARTITION_CUSTOMER_PRIV_PARAM_ADDR 0xfc000
#elif (SPI_FLASH_SIZE_MAP == 6)
#define SYSTEM_PARTITION_OTA_SIZE 0x6A000
#define SYSTEM_PARTITION_OTA_2_ADDR 0x101000
#define SYSTEM_PARTITION_RF_CAL_ADDR 0x3fb000

#else
#error "The flash map is not supported"
#endif #define SYSTEM_PARTITION_CUSTOMER_PRIV_PARAM SYSTEM_PARTITION_CUSTOMER_BEGIN uint32 priv_param_start_sec; static const partition_item_t at_partition_table[] = {
{ SYSTEM_PARTITION_BOOTLOADER, 0x0, 0x1000},
{ SYSTEM_PARTITION_OTA_1, 0x1000, SYSTEM_PARTITION_OTA_SIZE},
{ SYSTEM_PARTITION_OTA_2, SYSTEM_PARTITION_OTA_2_ADDR, SYSTEM_PARTITION_OTA_SIZE},
{ SYSTEM_PARTITION_RF_CAL, SYSTEM_PARTITION_RF_CAL_ADDR, 0x1000},
{ SYSTEM_PARTITION_PHY_DATA, SYSTEM_PARTITION_PHY_DATA_ADDR, 0x1000},
{ SYSTEM_PARTITION_SYSTEM_PARAMETER, SYSTEM_PARTITION_SYSTEM_PARAMETER_ADDR, 0x3000},
{ SYSTEM_PARTITION_CUSTOMER_PRIV_PARAM, SYSTEM_PARTITION_CUSTOMER_PRIV_PARAM_ADDR, 0x1000},
};
和添加
void ICACHE_FLASH_ATTR user_pre_init(void)
{
if(!system_partition_table_regist(at_partition_table, sizeof(at_partition_table)/sizeof(at_partition_table[0]),SPI_FLASH_SIZE_MAP)) {
os_printf("system_partition_table_regist fail\r\n");
while(1);
}
} `
然后makefile中修改
BOOT?=new
APP?=2
SPI_SPEED?=40
SPI_MODE?=QIO
SPI_SIZE_MAP?=2
支持FOTA 。
烧录进ESP-12S后，发生错误，不断重启，后来一句一句验证，错误语句是
system_param_load(ESP_PARAM_START_SEC, 0, &save_flash_data,
sizeof(save_flash_data));，
其中
struct esp_platform_saved_param { uint8 devkey[40];uint8 token[40];uint8 activeflag;uint8 pad[3];uint8 socket_switch_flag; //开关状态存储uint8 calibration_flag; //电压电流校准标志，为0没有校准，为1则校准过uint8 calibration_voltage_pulse[2] ;//电压脉冲值uint8 calibration_current_pulse[2] ;//电流脉冲值 uint8 electricity_value[4] ; //电量值uint8 time_switch_num; //定时个数uint8 time_switch[81]; //存放定时数据6个 uint8 calibration_voltage[2] ; //APP获取到的电压值 校准用uint8 calibration_current[2] ; //APP获取到的电流值uint8 server_dns[32]; //域名保存uint8 updata_flag; //升级标志uint8 time_zone[32]; //时区保存uint8 updata[3]; //预留uint8 ssid[32]; //SSIDuint8 password[64]; //密码 uint8_t iPhone_ip[4];
};是348字节，
#define ESP_PARAM_START_SEC 0x7D
烧录配置选的8Mnit。
无线重启 报错：
Fatal exception 9(LoadStoreAlignmentCause): epc1=0x4000438f, epc2=0x00000000, epc3=0x00000000, excvaddr=0x3f
