From 0297bd1106bc59f46ba4401bb50a0cdc9afc9faa Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 5 Apr 2016 10:54:06 +0200 Subject: [PATCH] arm: mx5: Fix NAND image generation The echo -ne "\xNN" does not work in certain bourne-compatible shells, like dash. The recommended way of hex->char conversion is using printf(1), but there is a pitfall here. The GNU printf does support "\xNN" format, but according to the opengroup documentation, this is not part of POSIX. The POSIX printf only defines "\NNN" where N is octal. Thus, for the sake of compatibility, we use that.
