Widy/Installing/New
From charlesreid1
New guide to installing everything from scratch on the Widy.
steps
Get version 2 of firmware here: https://wiki.openwrt.org/toh/tp-link/tl-mr3040#version_2x
Use Chaos Calmer: https://downloads.openwrt.org/chaos_calmer/15.05/ar71xx/generic/openwrt-15.05-ar71xx-generic-tl-mr3040-v2-squashfs-factory.bin
Do not use Barrier Breaker, it has kernel problems with usb /scsi kernel modules.
Flash router with firmware image (if already running OpenWrt, go to web console and pick System > Flash Firmware, if using built-in admin panel then do System Tools > Firmwware Upgrade).
Connect Widy to internet. Either connect ethernet cable, or use web control panel to connect to a wifi network as a client.
And... we can install kmod-usb-storage, but we run out of space before we can install kmod-fs-ext4.
That means we're stuck with Barrier Breaker, and if we can't get Barrier Breaker's kernel modules working, this entire venture is all... worthless.
opkg config
Maybe this is the problem?
/etc/opkg.conf config file seems to be on chaos calmer even though I re-flashed with barrier breaker image.
dest root / dest ram /tmp lists_dir ext /var/opkg-lists option overlay_root /overlay options check_signature 1

Nope. That wasn't the problem.
insmod
Via this thread: https://dev.openwrt.org/ticket/19351
Tried the following commands:
root@dropbear:~# insmod scsi_mod root@dropbear:~# insmod sd_mod
Then removed and installed:
root@dropbear:~# opkg install kmod-usb-storage Package kmod-usb-storage (3.10.49-1) installed in root is up to date. root@dropbear:~# opkg remove kmod-usb-storage Removing package kmod-usb-storage from root... root@dropbear:~# opkg install kmod-usb-storage Installing kmod-usb-storage (3.10.49-1) to root...

That seemed to work okay.
Next came ext4:
root@dropbear:~# opkg install kmod-fs-ext4 Installing kmod-fs-ext4 (3.10.49-1) to root... Downloading http://downloads.openwrt.org/barrier_breaker/14.07/ar71xx/generic/packages/base/kmod-fs-ext4_3.10.49-1_ar71xx.ipk. Installing kmod-lib-crc16 (3.10.49-1) to root...

Uh oh. Try removing/re-installing:
root@dropbear:~# opkg remove kmod-fs-ext4 Removing package kmod-fs-ext4 from root... root@dropbear:~# opkg install kmod-fs-ext4 Installing kmod-fs-ext4 (3.10.49-1) to root... Downloading http://downloads.openwrt.org/barrier_breaker/14.07/ar71xx/generic/packages/base/kmod-fs-ext4_3.10.49-1_ar71xx.ipk. Configuring kmod-fs-ext4. kmod: module is already loaded - mbcache kmod: module is already loaded - jbd2 kmod: failed to insert /lib/modules/3.10.49/ext4.ko
No luck. Keep pressing forward...
Install block-mount:
root@dropbear:~# opkg install block-mount Installing block-mount (2014-06-22-e0430f5c62f367e5a8e02755412977b02c3fc45e) to root...

Note that this post (https://www.loganmarchione.com/2014/10/openwrt-with-openvpn-client-on-tp-link-tl-mr3020/) states that the kernel plugin failures may be solved by plugging in the flash drive and rebooting the router.
