NetBSD/evbarm on pcDuino3 Nano - BSD小僧の日記

NetBSD/evbarm on pcDuino3 Nano
2014/12/22(月) 20:40 ［NetBSD］｜ Tweet

この記事はNetBSD Advent Calendar 2014の22日目の記事です。

Maker Faire Tokyo 2014で購入した pcDuino3 NanoでNetBSD/evbarmを動かしてみました。会場では4,500円で売られており、オマケでアクリル板のケースを付けてもらいました。

秋月電子では6,480円で売っているようなので、けっこうお得に入手したかもしれません。

■ pcDuino3 Nanoの基本スペック

まずはスペックです。AllwinnerのA20を積んだシングルボードコンピュータです。4,500円とは思えない豊富なインタフェースですね。

CPU	AllWinner A20 SoC, 1GHz ARM Cortex A7 Dual Core

DRAM	1GB
Onboard Storage	4GB Flash, microSD card (TF) slot for up to 32GB
Video Output	HDMI 1.4 with HDCP support
Network interface	Ethernet 10M/100M/1Gbps
Audio out	3.5mm analog audio interface
IR	IR reciever

■シリアルコンソール

なにはなくともシリアルコンソールです。写真のようにRx, Gnd, Txが出ています。

通信するためのシリアルポート設定は次のとおりです。

baud rate : 112500
data : 8bit
parity : none
stop bit : 1 bit
flow control : none

■ ブートローダはu-boot

NetBSDカーネルを読ませるための重要な要素であるところのブートローダ。u-bootが使われています。

コマンド一覧を見てみましょう。

sunxi#help
?       - alias for 'help'
base    - print or set address offset
boot    - boot default, i.e., run 'bootcmd'
boota   - boota   - boot android bootimg from memory

bootd   - boot default, i.e., run 'bootcmd'
bootm   - boot application image from memory
cmp     - memory compare
cp      - memory copy
crc32   - checksum calculation
env     - environment handling commands
exit    - exit script
false   - do nothing, unsuccessfully
fastboot- fastboot- use USB Fastboot protocol

fatdown - download data to a dos filesystem
fatinfo - print information about filesystem
fatload - load binary file from a dos filesystem
fatls   - list files in a directory (default /)
go      - start application at address 'addr'
help    - print command description/usage
key_test- Test the key value and dump key registers
loop    - infinite loop on address range
md      - memory display
mm      - memory modify (auto-incrementing address)
mmc     - MMC sub system
mmcinfo - display MMC info
mtest   - simple RAM read/write test
mw      - memory write (fill)
nand    - NAND sub-system
nboot   - boot from NAND device
nm      - memory modify (constant address)
printenv- print environment variables
reset   - Perform RESET of the CPU
run     - run commands in an environment variable
saveenv - save environment variables to persistent storage
setenv  - set environment variables
showvar - print local hushshell variables
sunxi_flash- sunxi_flash sub-system
test    - minimal test like /bin/sh
true    - do nothing, successfully
version - print monitor, compiler and linker version

FATファイルシステムを読むfatload, fatlsあたりはありますね。一方で、ネットワーク経由でファイルを取ってきてメモリに展開するtftp関連のコマンドはないようです。うーん、ネットワーク経由が使えないとなると、SDHCやらUSBメモリの抜き差しが多発して面倒なんですよね。

■ u-bootでSDHCにアクセスできない

どうやらu-bootからSDHCが見えていないようです。
SDHCからカーネルを読んでくるという手は使えなさそうです。

sunxi#mmc list
No MMC device available
sunxi#mmc info
No MMC device available
sunxi#mmc dev 0 1
No MMC device available
sunxi#fatls mmc 0:1

** Unable to use mmc 0:1 for fatls **
sunxi#

■ NAND flashにはアクセスできる

幸運なことにNAND flashにはu-bootからアクセスできます。
つまり、NAND flashにNetBSDカーネルを置けば、u-bootからロードできるというわけです。

sunxi#fatls nand 0
   124256   boot_signature.axf
   344813   font24.sft
            os_show/
  6498840   uimage
   121580   boot.axf
   357443   font32.sft
   222916   drv_de.drv
   287936   sprite.axf
   232872   drv_hdmi.drv
   226316   prvt.axf
   222900   drv_de_lvds.drv
    50660   script.bin
   121984   boot_lvds.axf
            linux/
      121   boot.ini
      512   magic.bin

15 file(s), 2 dir(s)

■ SDHCは壊れているわけではない

SDHCがハード的に壊れているのかと思ったのですが、どうやらそうではないようです。というのも、Linuxを起動するとSDHCには問題なくアクセスできるのです。

ということで、SDHCに格納したNetBSDカーネルをNAND flashにコピーしてやれば、u-bootからNAND flashを介してNetBSDカーネルを起動できるはずです。

まず、PCなどで（買ったときそのままの）MS-DOSフォーマットされたSDHCカードを用意し、NetBSDカーネルをコピーします。この際、コピーするのはbinary形式のnetbsd.binとなります。今回は、ftp.jaist.ac.jpからダウンロードした201412190900ZなNetBSD-currentを使いました。

root@ubuntu:~# mount -t msdos /dev/nanda /mnt
root@ubuntu:~# ls /mnt
boot.axf      boot_s~1.axf  drv_hdmi.drv  linux      prvt.axf    uimage
boot.ini      drv_de.drv    font24.sft    magic.bin  script.bin
boot_l~1.axf  drv_de~1.drv  font32.sft    os_show    sprite.axf
root@ubuntu:~# mount | grep mmcblk
/dev/mmcblk0p1 on /media/3465-6634 type vfat (rw,nosuid,nodev,uid=1001,gid=1002,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks)
root@ubuntu:~# cp /media/3465-6634/netbsd.bin  /mnt/netbsd.bin
root@ubuntu:~# sync;sync;sync; reboot

コピーが終わったら、一旦リブートしてu-bootに戻ります。
u-boot上でNAND flashからNetBSDカーネルをロードします。

sunxi#fatls nand 0
   124256   boot_signature.axf
   344813   font24.sft
            os_show/

   222916   drv_de.drv
   287936   sprite.axf

   121984   boot_lvds.axf
            linux/
      121   boot.ini
      512   magic.bin
  5286336   netbsd.bin

15 file(s), 2 dir(s)

sunxi#fatload nand 0 0x40007800 netbsd.bin
reading netbsd.bin

5286336 bytes read

ちょっとまって！　0x40007800って何ですか？　と思った人もいるかもしれません。

Allwinnerの設定ファイルevbarm/conf/std.awinを見て、ここかなー、って感じですね。

     26 makeoptions	KERNEL_BASE_PHYS="0x40007800"
     27 makeoptions	KERNEL_BASE_VIRT="0x80007800"

■ いよいよ起動！

ロードしたNetBSDカーネルの先頭アドレスである0x40007800から実行します。

見事に起動です！

■ めちゃくちゃ遅い？

SDHCカードが刺しっぱなしになっていませんか？　SDHCカードを取り除くとまともな速度で動くはずです。

もしSDHCカードを刺しっぱなしにしていると、次のようなログが表示され続けるはずです。

awinmmc0: timeout updating clock
sdmmc0: couldn't supply clock

■ マルチユーザモード

SDHCは残念な感じですが、USBデバイスは問題ありません。

ということで、USBメモリ上にルートファイルシステムを展開して、マルチユーザモードで起動してみます。USBメモリに配布物(base.tgz, etc.tgz, modules.tgzなどお好み)を展開し、デバイスファイルを作ったりfstabを書いたりと、NetBSDとしては共通のプロセスを実行します。

このあたりはfurandon_pigさんがNetBSD Advent Calendar 2014 16日目の記事に詳しく解説されているのでそちらをご参照ください。

さて、マルチユーザでの起動です。

■ まとめ

ここ最近のNetBSDにおけるAllwinnerのサポートの充実の恩恵をバッチリ享受して、大きな苦労なくNetBSDが動いています。

一方、Gigabit NICやSDHCなど動いておらず、まだまだやることはありそうです。あ、あとマルチプロセッサが動いてませんね。

また、HDMIやSATAについては試していません。このあたりも動いてくれるとかなり楽しそうですね。
