Yaffs Transplantation of linux3.6.5 __linux

1, download the source code.

Enter the Urdir directory (for description convenience, the Yaffs file is downloaded to the Urdir directory, the kernel source directory is urdir/linux3.6.5).

If the system has already installed the Git tool, execute directly:

Git clonegit://www.aleph1. CO.UK/YAFFS2 (@qingwu: Git is generally supported under the terminal)

If there is no Git tool, first download and install Git (http://git-scm.com/, if under Fedora, can be directly yum installed, command: Yum installgit.i686). of course, you can also download the Git tool under Windows (Please note: Windows files may appear in the error of carriage return line, such as ^m can not recognize, etc., you may refer to:

http://blog.csdn.net/cocoxiaomei/article/details/8497929)

2, to the core to make patches

After downloading the yaffs source code, enter the Urdir/yaffs source code directory and execute:

#. /patch-kernel.sh c M.. /linux-3.6.5

According to the help documentation, you know what C M means (you wish to copy (c) or link (l) the code and the path to your kernel sources and whether youwant to use  The Single-version or multi-version code.) 3, into the kernel source directory, configure the kernel, command: [root@localhostlinux-3.6.5] #make menuconfig, into the kernel configuration interface.

File Systems--->

[*] Miscellaneous filesystems---> <*> yaffs2 file system support

If there are no yaffs configuration options found in the file system configuration interface, Workaround:

In the configuration interface, look for/yaffs and find the illustration:

where the parameter in [] is the current state of the corresponding option, the YAFFS_FS option is [y], dependent on misc_filesystems and mtd_block for [y], but the latter is currently in [n], so it needs to be selected as [y]. Please configure it yourself.

4 If here direct make , the following sequence of errors occurs, and the resolution is given in the wrong corresponding row.

The file directories mentioned need to be modified are:

[Root@localhost linux-3.6.5]# vim include/linux/fs.h [root@localhost linux-3.6.5]# vim FS/YAFFS2/YAFFS_VFS.C [ Root@localhost linux-3.6.5]# Vim FS/YAFFS2/YAFFS_MTDIF.C

5, modified to complete, in the source directory make can be. [Root@localhost linux-3.6.5]# make the rest of the work is to burn to the Development Board to write the kernel.
