Buildroot 配置
Kernel -> wifi modle -> AP6212
Kernel -> wifi modle -> wifi fw local path (wifi固件路径)
- 相关安装包主要是：
buildroot/package/wifi-fw/wifi_fw.mk
主要如下:
AP6212) \
mkdir -p $(TARGET_DIR)/etc/wifi/6212; \
$(INSTALL) -D -m 0644 $(@D)/bcm_ampak/config/6212/*.bin $(TARGET_DIR)/etc/wifi/6212/; \
$(INSTALL) -D -m 0644 $(@D)/bcm_ampak/config/6212/nvram.txt $(TARGET_DIR)/etc/wifi/6212/nvram.txt; \
$(INSTALL) -D -m 0644 $(@D)/bcm_ampak/config/6212/BT/*.hcd $(TARGET_DIR)/etc/wifi/6212/; \
$(INSTALL) -D -m 0644 $(@D)/bcm_ampak/config/config.txt $(TARGET_DIR)/etc/wifi/6212/; \
