Tried flashing from OpenWrt without success, different platform
PLATFORM=TLMR3020
. MR3020 and WR703n are same hardware (with minor changes of more LEDs and one switch) for EU and CH market. Tried installing bfgminer on OpenWrt, but not enough space, at the start I have 80% available memory. I don't know what packages I could remove to make more room for bfgminer. Anyone could help?

The scripts I use for compiling the 703n firmware are available on Github:
https://github.com/nwoolls/BFGMiner-OpenWrt-Toolsand the package list I use:
libcurl libpthread jansson libusb-1.0 kmod-usb-serial kmod-usb-serial-cp210x kmod-usb-serial-ftdi kmod-usb-acm -kmod-gpio-button-hotplug hotplug2 -dnsmasq -uboot-envtools -6relayd -libgcc -libc -firewall -iptables -ip6tables -swconfig -ppp -ppp-mod-pppoe -kmod-ipt-nathelper -kmod-ledtrig-netdev libncurses screen
Thx for the support, still don't know should platform be changed in line 7 of cross-compile-bfgminer.sh to something else for MR3020? I think I'm very close bricking this small thing. Maybe I'll try to exchange MR3020 for WR703n and save it's life...
