From d0b89e48d712725c341842e60aadf802b6debc29 Mon Sep 17 00:00:00 2001 From: Michael Kuron Date: Sun, 1 Jul 2018 10:03:38 +0200 Subject: [PATCH] lantiq: enlarge AVM Fritz!Box 3370 flash Increase the available flash memory size in AVM Fritz!Box 3370 by incorporating the unused extra partitions located after the ubi partition. Note that users upgrading from a previous OpenWRT version need to re-install from the boot loader to pick up the new partition layout. Available flash space for rootfs+overlay increases from 48MB to 124MB. Reverting to the OEM firmware is still possible (via the recovery utility provided by AVM) as the OEM firmware appears to reformat the config and nand-filesystem partitions upon first boot if necessary. The reserved-kernel and reserved-filesystem partitions are overwritten by the OEM firmware when installing an update, so their contents do not matter. Boot loader and device-specific information (MAC addresses, calibration data, etc.) are not located in NAND flash and remain unharmed by this changed. Tested with OEM firmware 06.54 on device with HWRevision 5 and Micron flash chip.
