[OpenWrt-Devel] [PATCH v2] ramips: Add support for Netgear EX2700

Thu Jan 21 04:44:37 EST 2016


This patch adds support for the Netgear EX2700 and builds an approriate 
sysupgrade image. 
 
What's missing is the option to build a factory image flashable via the 
router's stock web interface, but this approach is hindered by the fact 
that u-boot operforms an additional integrity check, which expects a 
uImage header in the last 64 bytes of the "kernel" partition, which
the bootloader expects to be 960k, a size exceeded by the standard 
OpenWrt kernel.

Changes for v2:
* Fix alphabetical ordering (image/Makefile is not really sorted, so I've
put the EX2700 immediately below the E1700).
