Linux distribution for embedded devices.
Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developer, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

ea6200

linksys ea6200

lets download the original fw from linksys
binwalk  FW_EA6200_1.1.41.164830_prod.img
i renamed it to ea6200_direct.img
lets binwalk a lil bit

we see

lets cut the trx header out
cli:
dd if=ea6200_direct.img of=trx_header.bin bs=1 count=28

we get n file called trx_header.bin
next lets cut the lzma out
cli:
dd if=ea6200_direct.img of=lzma.bin bs=1 skip=28 count=1990256
we get an file called lzma.bin out
so last is the rootfs
dd if=ea6200_direct.img of=squashfs_rootfs.bin bs=1 skip=1990256
