kld problem at Atheros AR9132

Fri Feb 10 03:35:32 UTC 2017

Hi.

I use ZRouter build system. This tools build ELF kernel first by buildkernel.
Then ELF kernel convert to kbin by use objcopy command. 

ELF -> kbin -> LZMA -> U-BOOT -> block pad

microserver % file Buffalo_WZR-HP-G301NH_kernel*
Buffalo_WZR-HP-G301NH_kernel:                         ELF 32-bit MSB executable,
 MIPS, MIPS32 version 1 (FreeBSD), dynamically linked, interpreter /red/herring,
 not stripped
Buffalo_WZR-HP-G301NH_kernel.kbin:                    data

Old U-Boot can't boot ELF kernel dirctory.

This is good command.

microserver % objcopy -V
