My configs are based on DB120, but some parts are left out (there is no wifi on my device). See attachments. However, it does not fully boot - kernel seems to be up and running, but neither USB nor ethernet works for me, this means no way to mount rootfs. Also there is a dmesg (actually serial console log) attached. It seems there is OpenWrt working on this device, see dmesg I found at https://dev.openwrt.org/attachment/ticket/13585/log, but I was not able to verify this. I need openwrt-ar71xx-nand-vmlinux-initramfs.elf file as I do not want to erase MikroTik's RouterOS from the device, yet, but every one I found was just too old to support correctly RB2011L. I found also a page describing a way to build OpenWrt on FreeBSD at http://caia.swin.edu.au/urp/diffuse/openwrt/buildunderfreebsd.html, but it did not work for me, tested on both 9.2-STABLE and 10.0-BETA4 systems. I have no Linux setup available, so I could not try to build OpenWrt this way either. I am now out of ideas, so would appreciate anything I could test to troubleshoot the issues I see. Oh, I have both ports 1 (gigabit, so on Ar8327 switch, necessary to do a ethernet boot on the device) and 6 (100 Mbit, on Ar8227 according to manufacturer's page found at http://wiki.mikrotik.com/wiki/Manual:Switch_Chip_Features). Also, if someone could build for me OpenWrt for this device suitable for netbooting, that would be also great - at least I could verify it really works so we could try to find relevant bits from OpenWrt's sources, for ethernet support it could be seen at https://dev.openwrt.org/browser/trunk/target/linux/generic/files/drivers/net/phy/ar8216.c, but finding the relevant bits in this 2584 lines of code intended for various Atheros switches is not (yet) easy for me :( There was a time when rootfs could be embedded easily in kernel, but I found no method to do id on current sources. If there is any method to do this, it will be possible to mount rootfs from md based ram disk and do some debugging on the RB2011 itself, thus overcoming the troubles with not (yet) working ethernet and USB on this device.
