Belkin RT-3200 / Linksys E8450
|

|
|
******************************
|
||
|
|
|
||
|
|
This device is based on a 64 bit Mediatek MT7622 ARM platform,
|
||
|
|
and is "work in progress" in Liminix.
|
||
|
|
|
||
|
|
The factory flash image contains ECC errors that make it incompatible
|
||
|
|
with Liminix: you need to use the `OpenWrt UBI Installer <https://github.com/dangowrt/owrt-ubi-installer>`_ to rewrite the partition layout before
|
||
|
|
you can flash Liminix onto it (or even use it with "tftpboot",
|
||
|
|
if you want the wireless to work).
