From 2a1291807cfcc93beb57a7e6c942da680a86c78d Mon Sep 17 00:00:00 2001 From: Peter Korsgaard Date: Mon, 1 Dec 2008 17:13:17 +0100 Subject: [PATCH] tools/mkimage: use lseek rather than fstat for file size for -l option Use lseek rather than fstat for file size for list mode, so mkimage -l /dev/mtdblockN works (stat returns st_size == 0 for devices). Notice that you have to use /dev/mtdblockN and not /dev/mtdN, as the latter doesn't support mmap.
