From 0cddb5e96a70c9d1449da52ecbb9d99f8d13974d Mon Sep 17 00:00:00 2001 From: hauke Date: Thu, 25 Oct 2012 19:49:20 +0000 Subject: [PATCH] brcm47xx: check for .ELF header in partition parser The image format for the wgt634u is different from the normal format. Without this patch the partition parser detects a 128kb bigger partition after every update. This closes #11420 Thank you b.sander for the patch. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@33935 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- .../brcm47xx/patches-3.3/050-mtd-add-bcm47xx-part-parser.patch | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/target/linux/brcm47xx/patches-3.3/050-mtd-add-bcm47xx-part-parser.patch b/target/linux/brcm47xx/patches-3.3/050-mtd-add-bcm47xx-part-parser.patch index 5381e2f6cc..0c66603f2e 100644 --- a/target/linux/brcm47xx/patches-3.3/050-mtd-add-bcm47xx-part-parser.patch +++ b/target/linux/brcm47xx/patches-3.3/050-mtd-add-bcm47xx-part-parser.patch @@ -26,7 +26,7 @@ obj-$(CONFIG_MTD_CHAR) += mtdchar.o --- /dev/null +++ b/drivers/mtd/bcm47xxpart.c -@@ -0,0 +1,542 @@ +@@ -0,0 +1,548 @@ +/* + * Copyright (C) 2006 Felix Fietkau + * Copyright (C) 2005 Waldemar Brodkorb @@ -96,6 +96,11 @@ + u32 offsets[TRX_MAX_OFFSET]; /* Offsets of partitions from start of header */ +}; + ++/* for WGT634U search the ELF-header of ++ * the kernel decompressor instead of TRX ++ */ ++#define WGT634U_ELF_MAGIC 0x464c457f /* ".ELF" */ ++ +/* for Edimax Print servers which use an additional header + * then the firmware on flash looks like : + * EDIMAX HEADER | TRX HEADER @@ -149,7 +154,8 @@ + } + + /* found a TRX header */ -+ if (le32_to_cpu(trx->magic) == TRX_MAGIC) ++ if (le32_to_cpu(trx->magic) == TRX_MAGIC || ++ le32_to_cpu(trx->magic) == WGT634U_ELF_MAGIC) + goto found; + } + -- 2.11.0
