I given mem according to what I saw in /proc/iomem 20000000-9fffffff : System RAM 20008000-207fffff : Kernel code 20900000-209a0c87 : Kernel data So I gave --mem-min 0x30000000 --mem-max 0x9fffffff Anyway, the result is always the same. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
