完整的文件名称:
gerneral-snapshot-r10923-7f2b230-ramips-mt76x8-Junda_P1905B-32m-squashfs-sysupgrade.bin
镜像名称的由来: IMAGE_NAME => IMG_PREFIX 生成， 而VERSION_DIST_SANITIZED、IMG_PREFIX_VERNUM是由version.k 分析来， vesion.mk的内容来自make menuconfig=>Image configuration=>Version configuration options 配置而来
IMG_PREFIX:=$(VERSION_DIST_SANITIZED)-$(IMG_PREFIX_VERNUM)$(IMG_PREFIX_VERCODE)$(IMG_PREFIX_EXTRA)$(BOARD)$(if $(SUBTARGET),-$(SUBTARGET))
参数说明:
VERSION_DIST_SANITIZED => OpenWrt => general
IMG_PREFIX_VERNUM=>VERSION_NUMBER=>snapshot
IMG_PREFIX_VERCODE=>VERSION_CODE=>r10923-7f2b230
IMG_PREFIX_EXTRA=>
BOARD=>ramips
SUBTARGET=>mt76x8-Junda_P1905B-32m
IMAGE_PREFIX := $(IMG_PREFIX)-$(1)
# IMAGE_NAME = $$(IMAGE_PREFIX)-$$(1)-$$(2)
$(1) squashfs
