rv1126-rv1109-yaffs2-mkyaffs2image610

今天使用了一下yaffs2功能

就是生成一个yaffs的包

从移植的角度先生成ro_1109.yaffs包

烧录进去

操作步骤：

创建和生成ro文件夹和 mkyaffs2image610可执行程序

然后用

fakeroot ./mkyaffs2image610 ro ro_1109.yaffs 1 2

生成了ro_1109.yaffs

例：

	@if [ "$(TARGET_DEPLOY_TYPE)" == "rodatafs" ] || [ "$(TARGET_DEPLOY_TYPE)" == "rwdatafs" ] || [ "$(TARGET_DEPLOY_TYPE)" == "rwfs" ];then \
		echo "Deploy $(TARGET_DEPLOY_TYPE) permissions to directory $($(patsubst %_$(FLASH_TYPE)_yaffs_fsimage,%,$@)$(RESOUCE))"; \
		$(FAKEROOT) /bin/bash $(DEPLOYER_SH) -s -P ${D_PRODUCT_TYPE} -d $(TARGET_DEPLOY_TYPE) -o $($(patsubst %_$(FLASH_TYPE)_yaffs_fsimage,%,$@)$(RESOUCE)) -- "$< $($(patsubst %_$(FLASH_TYPE)_yaffs_fsimage,%,$@)$(RESOUCE)) $(IMAGEDIR)/$(patsubst %_$(FLASH_TYPE)_yaffs_fsimage,%,$@)_202d.yaffs 1 2"; \
	else \
		echo "Create $(patsubst %_$(FLASH_TYPE)_yaffs_fsimage,%,$@) yaffs image"; \
		$(FAKEROOT) $(MKYAFFS2IMAGE) $($(patsubst %_$(FLASH_TYPE)_yaffs_fsimage,%,$@)$(RESOUCE)) $(IMAGEDIR)/$(patsubst %_$(FLASH_TYPE)_yaffs_fsimage,%,$@)_202d.yaffs 1 2; \
	fi;

//上面是存在ro_1109.yaggs文件做覆盖
//下面是不存在创建

升级ro_1109.yaffs

=============================移植cramfs================================

安装cramfs

sudo apt-get install cramfsprogs

//安装失败
E: Unable to locate package cramfsprogs

手动下载这个包
https://launchpad.net/ubuntu/xenial/+package/cramfsprogs
http://mirror4.nyist.edu.cn/ubuntu/ubuntu/pool/main/c/cramfs/cramfsprogs_1.1-6ubuntu1_amd64.deb

cramfsprogs_1.1-6ubuntu1_amd64.deb
安装
sudo dpkg -i cramfsprogs_1.1-6ubuntu1_amd64.deb

参考博客:Ubuntu 18.04 安装cramfsprogs_cramfs deb-CSDN博客

然后手动对文件系统打包

存在问题,编译出来的固件会死机,先存档.
