I've installed header for serial port, puzzled out the pins, found your blog that had the pins and the piece I was missing (the baud rate). I now have added it to my test lab's terminal server and hope to start building images for it once I get my test lab's CI infrastructure up and running.

You need make small rootfs because of this target flash is too small.
ZRouter is make cd9660 rootfs image by limited files and uzip.
And 64Kbyte synced kernel image append rootfs uzip.

+-------------------+------+-----------+
|u-boot kernel image|synced|rootfs uzip|
+-------------------+------+-----------+

This is complete image.

Also you need fixed rootfs address in dts.

sys/dts/arm/wzr2-g300n.dts

This is flash u-boot command.

5VT1310-EVB# tftpboot 0x00800000 Buffalo_WZR2-G300N.zimage

5VT1310-EVB# erase 0x1F010000 0x1F3CFFFF

5VT1310-EVB# cp.b 0x00800000 0x1F010000 $(filesize)

5VT1310-EVB# reset

I make auto scan rootfs partition patch at geom_flashmap.

https://reviews.freebsd.org/D13648

This patch scan rootfs in named firmware partition.

I have many time stop at mountroot. This patch is solution this.
