I just got my hands on the itsy-bitsy TL-WR802N v4 and I'd love to put openwrt on it, but I haven't found any firmware builds for it. I have seen some for the v1 and v2 hardware revisions, but those run on Qualcomm Atheros, while the v4 runs on MediaTek (at least according to wikidevi) so I don't think the firmware will be forwards compatible (and I'd rather not brick it if I don't have to).
Can anyone offer some help in finding/building an openwrt firmware.bin for this router?
