Target Board ubi tool cross-Compilation

To use ubifs on the target board, you need some ubi tools, which can be obtained from the MTD-utils tool.

The cross-Compilation Method for mtd-utils-1.2.0 has been introduced in previous articles, but this version of software can only get the ubi tool for the target board, without the ubi tool for the host. The mtd-1.3.0 and above contain ubi tools for the target end and host. Compilation on the host has been introduced, and now introduces the cross-compilation mtd-utils-1.4.2. It is also compiled in the Fedora Core 9 environment. Of course, like the cross-compilation mtd-1.2.0, zlib, lzo are indispensable for cross-compilation, and installed into the cross tool chain, no longer introduced. Cross-compilation mtd-1.4.2 also requires UUID, UUID included in e2fsprogs software package, so download for cross-compilation. ---------------------------------------------------------------------------------- Download e2fsprogs:Wget http://prdownloads.sourceforge.net/e2fsprogs/e2fsprogs-1.41.14.tar.gz cross compiling Script :. /configure -- Host = arm-VFP-Linux -- enable-elf-shlibs \ -- prefix =/opt/NXP/gcc-4.3.2-glibc-2.7/ARM-VFP-Linux-GNU/Makemake installmkdir/opt/ NXP/gcc-4.3.2-glibc-2.7/ARM-VFP-Linux-GNU/include/uuidcp lib/UUID. h/opt/NXP/gcc-4.3.2-glibc-2.7/ARM-VFP-Linux-GNU/include/UUID/install libuuid and UUID. h file.

Jffs2 errors may occur during compilation. If you do not want to see these errors, you can remove the items related to jffs2 in makefile. After compilation, generate flash_erase and other tools under the arm-VFP-Linux-gnu directory, generate libmtd library under the arm-VFP-Linux-GNU/lib directory, and convert libmtd. copy A to the cross tool chain directory.
