From 5832e754fbf502a7d2f2d7bee054eae1b6ad0520 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 25 Jul 2012 17:28:32 +0000 Subject: [PATCH] mtd: fix trx_fixup With the BRCM47xx image I have built (Linksys E3000), there are additional writes following the completion of "mtd_replace_jffs2" which invalidate the 'trx_fixup' performed by 'mtd_replace_jffs2'. Moving the 'trx_fixup' to somewhere after all writes have completed fixes the problem. I also noticed that 'erasesize' used to compute 'block_offset' in 'mtd_fixtrx' is used before it is computed by 'mtd_check_open'; moving the call to 'mtd_check_open' up a few lines fixes this. Unlike 'mtd_fixtrx', 'trx_fixup' appears to assume that the TRX header is always at offset 0; which may be the cause of the problem described in Ticket #8960.
