From 7e128632522988513c90e5fda44e6aab5b9f21cf Mon Sep 17 00:00:00 2001 From: Mathias Kresin Date: Sun, 18 Jun 2017 10:28:18 +0200 Subject: [PATCH] fritz_tffs_read: get tffs size from input file Use the size of the input file as maximum tffs size instead of a fixed value. The tffs on a AVM Fritz 300E can be up to 512KByte for example. Fixes a read error for the AVM Fritz 3370 where the tffs partition size is 64Kbyte and smaller than the former default value of 256KByte.
