According to TP-Link support the most recent version 2.1 of the TL-WR710N has again 8MB of flash- in contrast to v2.0.
According to  https://wiki.openwrt.org/toh/tp-link/tl-wr710n that version is supported by 15.05. Unfortunately 15.05 and also the latest snapshot just create images for the 4MB Flash.

Would it be sufficient to modify the target/linux/ar71xx/image/Makefile in the Imagebuilder to:

define Device/tl-wr710n-v2
    $(Device/tplink-8mlzma)
    BOARDNAME := TL-WR710N
    DEVICE_PROFILE := TLWR710
    TPLINK_HWID := 0x07100002
    CONSOLE := ttyATH0,115200
endef

to get a working image, that makes the whole flash available?
make image PROFILE=TLWR710 at least results in a larger image:
8126464 Nov 11 19:26 openwrt-ar71xx-generic-tl-wr710n-v2-squashfs-factory.bin

As I recently bricked another device irrevocable I would like to ask the specialists here before applying that image

As the internal structure changed, it is probably a good idea not to install one of the existing wr710n images to the new version 2.1:

Version 1.2:
mtd0: 00020000 00010000 "u-boot"
mtd1: 00127468 00010000 "kernel"
mtd2: 006a8b98 00010000 "rootfs"
mtd3: 00090000 00010000 "rootfs_data"
mtd4: 00010000 00010000 "art"
mtd5: 007d0000 00010000 "firmware

Version 2.0:
mtd0: 00020000 00010000 "u-boot"
mtd1: 00143a0c 00010000 "kernel"
mtd2: 0028c5f4 00010000 "rootfs"
mtd3: 000a0000 00010000 "rootfs_data"
mtd4: 00010000 00010000 "art"
mtd5: 003d0000 00010000 "firmware"

Version 2.1
0x000000000000-0x000000020000 : "u-boot"
0x000000020000-0x000000120000 : "kernel"
0x000000120000-0x0000007e0000 : "rootfs"
0x0000007e0000-0x0000007f0000 : "config"
0x0000007f0000-0x000000800000 : "ART"

So it seems, the latest version of that device is currently not supported.

Hi Given this knowledge of the layout how much should I strip for the front of the V 2.0 stock firmware before installing it?

I'd like to modify the instructions here
http://tech.saoslab.com/post/2014/06/18 … k-firmware
to revert my TP-Link TL-WR710N V2.0 to stock as there isn't space for any additional packages & I have a V2.1 to play with now.

Thank you in advance
