Changing the Firmware

The development branch of OpenWRT experimentally supports AR7 devices. OpenWRT has been successfully installed on a Fritz!Box SL. The 3070 might require a different flash memory layout.

Changing the memory layout

Original memory layout:

mtd0	0x90000000	0x90000000
mtd1	0x90010000	0x903c0000
