** Edit zrouter/boards/Buffalo/WZR-HP-AG300H/board.mk
Specify board flash size
<pre>
BOARD_FLASH_SIZE=32M
</pre>
Specify board memory
<pre>
# Board have 128M of RAM
KERNCONF_OPTIONS+= AR71XX_REALMEM=128*1024*1024
</pre>
Set maximum firmware size
<pre>
# Image must not be biggest than GEOM_MAP_P2 (upgrade part.)
FIRMWARE_IMAGE_SIZE_MAX=0x00760000
</pre>
* Build
** make TARGET_PAIR=Buffalo/WZR-HP-AG300H. This will produce Buffalo_WZR-HP-AG300H.zimage under $OBJ_DIR/...
** Prepare TFTP image. I have used buffaulo-tftp utility from OpenWRT (in future should be included into build) image (buffaulo-tftp)
<pre>
(echo -n "# Airstation FirmWareNrun u_fwNresetNN" | tr "N" "\012" | dd bs=512 count=1 conv=sync; dd if=Buffalo_WZR-HP-AG300H.zimage) > tftp.tmp
buffalo-tftp -i tftp.tmp -o Buffalo_WZR-HP-AG300H-tftp.bin
</pre>
Resulting Buffalo_WZR-HP-AG300H-tftp.bin can be flashed via tftp. (I believe Buffalo_WZR-HP-AG300H.zimage can be flashed via OpenWRT upgrade utility, but I never tried)
* flash
** TFTP flash procedure described in http://wiki.openwrt.org/toh/buffalo/wzr-hp-ag300h
