Do you need that patch to work in little-endian: https://dev.openwrt.org/browser/trunk/target/linux/ar7/patches-2.6.30/500- serial_kludge.patch ? If so, you are likely to need it in big-endian too since it works around a silicon issue. -- Best regards, Florian Fainelli Email: florian@xxxxxxxxxxx Web: http://openwrt.org IRC: [florian] on irc.freenode.net -------------------------------
