installing a DLNA server (minidlna) and mounting a USB stick - Xiaomi Mini

get the minidlna package

opkg install minidlna

and i also installed the luci config app to make things easier to configure

opkg install luci-app-minidlna 

and when reloading luci you'll a services tab with minidlna.

now unless you plan on serving your media from NVRAM you probably will want to mount a USB stick to serve your files from.

the Xiaomi mini wifi comes with one USB2 (highspeed port) and usbcore is part already part of the image (CC-RC2) but you'll still need to add the mass storage driver, and some filesystem support (e.g for windows formatted FAT32 stick):

opkg install kmod-usb-storage block-mount kmod-fs-vfat kmod-nls-cp437 kmod-nls-iso8859-1

(note:the block-hotplug package is merged into block-mount, wiki isn't updated yet)
it complains about fstab missing but you can create a default file with

block detect > /etc/config/fstab

for some reason i had to reboot the router at this stage)
(ie usb device detect but no /dev/sda being created)

anyhoo, from that point on you can add your mountpoint in fstab or using LuCI
(a new subtab mountpoints will have been created under system)
i mounted mine under /data
