RaspberryPi4にNetBSD/aarch64を試す

1. http://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/latest/evbarm-aarch64/binary/gzimg/arm64.img.gz をダウンロード
2. gzcat arm64.img.gz | sudo dd of=/dev/sd1d bs=32k でmicroSDカードに書き込み
3. microSDカードを挿す
4. 6、8、10番ピンにUARTのGND、TX、RXを繋ぐ（CubieBoard2で使っているやつを拝借）
5. USBコネクタを挿して電源投入

んで流れた起動メッセージがこれ。カーネルを読み込んで起動しているところまでは良いけども、どうもmicroSDである/dev/ld0が見えないらしい。

NYC*BUG dmesgd を見る限りだと去年の9月と12月で動作報告があるので、なにかしら設定を間違えたか単にこの後で何かバグったのか。

Date	From (nickname)	*BSD (derived)	Description
2019-09-01	mlelstv	NetBSD	RPI4 4GB
2019-12-30	jmcneill	NetBSD	NetBSD/evbarm 9.99.31 on Raspberry Pi 4 Model B (4GB, ACPI)

dmesgだけ見るとリビジョン表記が全員バラバラなのは気付いたけど流石にそこまで影響しないよなぁ…おそらく技適対応やUSBの給電回りの修正で1.2になったんだと思うし。
