Buildroot 配置

Kernel -> wifi modle -> AP6212
Kernel -> wifi modle -> wifi fw local path (wifi韌體路徑)

• 相關安裝包主要是：

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/; \
		;; \


系統根目錄/hardware/aml-4.9/amlogic/wifi/bcm_ampak/config/6212,主要韌體

可以發現/etc/wifi/6212/fw_bcm43438a1.bin打不開該檔案，由於系統中沒有該檔案導致的，最終找原廠提供最新AP6212韌體包，問題解決¹
