bfgminer/README.OpenWrt

First, look at /etc/openwrt_release (on your router). You will see a bunch of
attributes for the OpenWrt system. The DISTRIB_RELEASE attribute is your
OpenWrt version, the first part of DISTRIB_TARGET (before the slash) is the
router's platform, and (only on newer versions) DISTRIB_ARCH is the package
architecture. Older versions of OpenWrt (up to 15.05) use the router's
platform for packages instead of the package architecture.

Now, open up /etc/opkg.conf (again, on your router) in your favourite editor.
Add a new line at the bottom, similar to this:
	src/gz bfgminer http://luke.dashjr.org/programs/bitcoin/files/bfgminer/latest/openwrt/17.01/mips_24kc
In this example, 17.01 is the version of OpenWrt, and mips_24kc is the package
architecture. Be sure to change those to match your router! You can also change
"latest" to "stable" or "testing" to get better-tested versions.

Next, save the file and exit your editor. Tell opkg to reload its package lists
by running the command:
	opkg update
If you get a "404 Not Found" error, then your router may not be supported. If
you open an issue for your router's platform, it may be possible to add
support.

If all went well updating your package list, you can now install BFGMiner and
any drivers you might need:
	opkg install bfgminer
	opkg install kmod-usb-serial-ftdi
	opkg install kmod-usb-serial-cp210x
	opkg install kmod-usb-serial-pl2303
