MPP Sample 自动拷贝到打包的固件中
由于 MPP Sample 编译出来较大，所以默认没有拷贝到固件里，但是在出测试固件的时候需要将可执行的 Sample 也打包到固件里，方便测试烧写

这里以 sample_smartIPC_demo 为例，演示如何将 Sample 和对应配置文件配置自动打包到固件里

修改文件： openwrt/package/allwinner/eyesee-mpp/middleware/Makefile

define Package/$(PKG_NAME)/install
    $(INSTALL_DIR) $(1)/mnt/app
	if [ -d $(SRC_COMPILE_DIR)/install ]; then \
		$(CP) -r $(SRC_COMPILE_DIR)/install/* $(1); \
	else \
		echo "fatal error! why $(SRC_COMPILE_DIR)/install not exist?"; \
	fi
	$(CP) $(SRC_COMPILE_DIR)/sample/sample_smartIPC_demo/sample_smartIPC_demo $(1)/mnt/app
	$(CP) $(SRC_COMPILE_DIR)/sample/sample_smartIPC_demo/sample_smartIPC_demo.conf $(1)/mnt/app
endef

define Package/$(PKG_NAME)-demo/install
	@echo "package $(PKG_NAME)-demo has no libs or exeFiles to install.";
endef

@awwwwa 应该是flash坏了，4个flash坏了3个。第4个成功烧录

@awwwwa 用的PY25Q256HA，32MB。

换了一块新的nor flash， 能烧一次，断电后第二次又变成这样。

刚好碰到这个问题，谢谢分享

@xiaowenge 建议接入deepseek自动审核帖子，减少人工审核工作量。

非常感谢分享，刚开始学习

@ljtty 标题要吸引人，我觉得主要还是省了一个外挂wifi
