[LEDE-DEV] sysupgrade on lantiq xrx200 form openwrt to lede

[Florian Eckert]

Hello LEDE-Team

I am using a openwrt 15.05 on an lantiq xrx200 device.
Upgrade works always as expectet for 15.05.
I am using the squashfs tar file.

I wantet to test lede and i have seen that the image generation has
completly changed there is no tar file anymore only bin.
If i use this to make a sysupgrade command i always get the output

Could not open mtd device: firmware
Can't open device for writing!
Upgrade completed
Rebooting system...

In openwrt i always could untar the tar file. To see the structur CONTROL ...
In lede this does not work anymore.

What to i make wrong? Could you explain your changes?
