AI-WB2的easyflash文件系统，刷写程序、OTA后不掉数据哦

移植easyflash和另一个spiffs文件系统刷写程序、OTA后不掉数据原理都差不多，这里再说一次

查看项目下的Make File

This is a project Makefile. It is assumed the directory this Makefile resides in is a

project subdirectory.

PROJECT_NAME := LivingRoomCock PROJECT_PATH := $(abspath .) PROJECT_BOARD := evb export PROJECT_PATH PROJECT_BOARD #CONFIG_TOOLPREFIX :=

-include ./proj_config.mk

ifeq ($(origin BL60X_SDK_PATH), undefined) BL60X_SDK_PATH_GUESS ?= $(shell pwd) BL60X_SDK_PATH ?= $(BL60X_{S}D{K}_{P}AT{H}_{G}UESS)/../../../..$(info ****** Please SET BL60X_SDK_PATH ******) $(info\ast \ast \ast \ast \ast \ast TryingSDKPATH[$(BL60X_SDK_PATH)]) endif

COMPONENTS_NETWORK := sntp dns_server COMPONENTS_BLSYS   := bltime blfdt blmtd blota bloop loopadc looprt loopset COMPONENTS_VFS     := romfs cjson

INCLUDE_COMPONENTS += freertos_riscv_ram bl602 bl602_std newlibc wifi wifi_manager wpa_supplicant bl602_os_adapter wifi_hosal hosal mbedtls_lts lwip lwip_dhcpd vfs yloop utils cli aws-iot httpc httpd dns_server netutils blog blog_testc INCLUDE_COMPONENTS += easyflash4 coredump lwip_altcp_tls_mbedtls  blcrypto_suite bl_os_adapter rfparam_adapter_tmp spiffs

INCLUDE_COMPONENTS += $(COMPONENTS_NETWORK) INCLUDE_COMPONENTS += $(COMPONENTS_BLSYS) INCLUDE_COMPONENTS += $(COMPONENTS_VFS) INCLUDE_COMPONENTS += $(PROJECT_NAME)

include $(BL60X_SDK_PATH)/make_scripts_riscv/project.mk

最终调用make_scripts_riscv/project.mk

flash-only:         cd (APP_BIN) SDK_BOARD=$(PROJEC{T}_{B}OARD)SD{K}_{N}AME=$(PROJECT_NAME) SDK_MEDIA_BIN=$(AP{P}_{M}EDI{A}_{B}IN)SD{K}_{R}OMF{S}_{D}IR=$(APP_ROMFS_DIR) SDK_DTS=$(PROJEC{T}_{D}TS)SD{K}_{X}TAL=$(PROJECT_BOARD_XTAL) BL_FLASH_TOOL_INPUT_PATH_cfg2_bin_input=$(APP_BIN) $(FLAS{H}_{T}OO{L}_{T}YPE)--chipname=BL602--baudrate=$(SERIAL_BAUDRATE) --port=$(SERIA{L}_{P}ORT)--pt=$(BL60X_SDK_PATH)/tools/flash_tool/chips/bl602/partition/partition_cfg_4M.toml --dts=$(BL60X_{S}D{K}_{P}ATH)/tools/flas{h}_{t}ool/chips/bl602/devic{e}_{t}ree/04-b{l}_{f}actor{y}_{p}aram{s}_{I}oTKit{A}_{4}0M-20220625.dts--boot2=$(BL60X_SDK_PATH)/tools/flash_tool/chips/bl602/builtin_imgs/boot2_isp_bl602_v6.5.1/boot2_iap_release.bin --firmware=$(APP_BIN)

最终得出Flash分区文是/tools/flash_tool/chips/bl602/partition/partition_cfg_4M.toml。 备份文件partition_cfg_4M.toml文件

hal_boot2_partition_addr("spiffs",&addr0,&addr1,&size0,&size1,&active);这个函数可以得到分区文件partition_cfg_4M.toml的开始地址和大小。修改spiffs的起始地址和大小，cfg.phys_addr = addr0;cfg.phys_size = size0;spiffs文件系统就存在flash这个空间，烧写程序和OAT升级都不会破坏这个空间，也就是spiffs数据不会丢失。
ret = hal_boot2_partition_addr("spiffs",&addr0,&addr1,&size0,&size1,&active);
if (size1 < 8 * 1024) {
//printf("[ERROR]psm partition is less than 8k,easyflash can not work!");
return EF_ENV_INIT_FAILED;
}
else{
EF_START_ADDR = addr1;
ENV_AREA_SIZE = (size1 / EF_ERASE_MIN_SIZE) * EF_ERASE_MIN_SIZE;
SECTOR_NUM = ENV_AREA_SIZE / EF_ERASE_MIN_SIZE;

这个给easyflash使用。烧写程序和OAT升级都不会破坏这个空间，也就是easyflash 数据不会丢失。
