see https://dev.openwrt.org/ticket/22320 otherwise lede working fine on wndr3700v4 all ive noticed is /overlay isn't that big
Hostname lede Model NETGEAR WNDR3700v4 Firmware Version LEDE Reboot r1309 / LuCI Master (git-16.217.35130-6a11f71) Kernel Version 4.4.15
this was brought up on an arokh build on OpenWRT but i think he used a patch for it see https://forum.openwrt.org/viewtopic.php?pid=310362#p310362 and https://forum.openwrt.org/viewtopic.php?pid=310473#p310473 finally https://forum.openwrt.org/viewtopic.php?pid=311402#p311402
the netgear wndr 3700v4 have 128 nand flash space,the current Flash Layout, use OEM’s firmware MTD partition as Openwrt firmware mtd partition, but the MTD partition only have 25MiB, and at tail of the nand flash there have a 96MiB reserved MTD partition, the are also a reserved MTD partition in Openwrt. Whether it is possible use the reserved MTD partition as openwrt firmware MTD partition。 Or the are no way boot from an differ MTD partiton, IF not hack the bootloader; root@lede:~# df -h Filesystem Size Used Available Use% Mounted on /dev/root 2.3M 2.3M 0 100% /rom tmpfs 61.0M 1.5M 59.5M 2% /tmp /dev/ubi0_1 14.2M 9.7M 3.7M 72% /overlay overlayfs:/overlay 14.2M 9.7M 3.7M 72% / tmpfs 512.0K 0 512.0K 0% /dev
