PowerPC 版 LinkStation?/TeraStation?/玄箱の U-Boot に関するページです。 †
U-Bootとは †以前は、PPCBootという名前でPowerPC専用だったが、その後U-Bootに名称変更され、PowerPC以外の板もサポートするようになった。TFTPによるネットワーク経由でkernelをロードできるなど、非常に多機能なブートローダ。 LinkStation?/玄箱への移植 †U-Bootを初めてLinkStation?/玄箱に移植したのは、LinkStation?/玄箱のカーネルパッチでおなじみの虹野氏である。 残念ながら、その後Web上では公開されなくなった。それに代わり、Mr.Mihai Georgianが引き続きLinkStation?/玄箱への移植作業を行っている。 debug() を有効にする †U-Bootでは、デバッグ用に ソースコード中に debug() が組み込まれており、これを有効にすれば、起動中の状況をモニタリングできる。DEBUGオプションを定義してコンパイルすれば、debug() が有功になる。 $ diff -Nur config.mk.orig config.mk --- config.mk.orig 2010-05-24 15:40:01.000000000 +0900 +++ config.mk 2010-05-24 15:40:19.000000000 +0900 @@ -136,7 +136,7 @@ ARFLAGS = crv endif RELFLAGS= $(PLATFORM_RELFLAGS) -DBGFLAGS= -g # -DDEBUG +DBGFLAGS= -g -DDEBUG OPTFLAGS= -Os #-fomit-frame-pointer ifndef LDSCRIPT #LDSCRIPT := $(TOPDIR)/board/$(BOARDDIR)/u-boot.lds.debug ST Micro M29W320DT など 16bit mode も持っている FlashROM の問題 †This might sound confusing, so I've tried to say too much rather than too little in the hopes that it will help. First, I don't have a schematic, so I'm not sure how A1, A0 and/or BYTE# are wired. I'm still not sure if it's 8-bit or 16-bit in truth. Regardless, the CFI probe and detection code only works when all of the CFI table offsets are doubled. This is consistent with addressing a 16-bit flash, since the address lines are typically shifted by one bit. The A0 line (and up) on the flash are driven by A1 and up on the CPU. So byte addresses 0, 2, 4 would access flash word-addresses 0, 1, 2. This is a typical arrangement for 16-bit memory. In most cases the A0 line on the CPU is simply not connected. The mtd driver doesn't know what the board is doing, so to figure it out, it simply tries it both ways in the probe code. In our case, the probe is successful with an offset scaling factor of two. This is typical for a 16-bit word memory accessed by byte addresses. This "offset scaling factor" is called "cfi->device_type" in the mtd driver. Flash chips usually want to see commands written to the magic offsets 0x555 and 0x2aa. To get these offsets to appear at the 16-bit flash, the CPU writes to byte addresses 0xaaa and 0x555, which get shifted right due to the A1->A0 hookup, to become 0x555 and 0x2aa, which is what the flash wants to see. However, what the mtd driver does is it takes the magic offsets 0x555 and 0x2aa and it shifts them left using the scaling factor "cfi->device_type" to produce the necessary doubled CPU byte addresses. This is a problem because a shift-left of 0x2aa does not yield 0x555, but rather 0x554. I think this is the real problem. Unfortunately, the flash chip really does want the CPU to generate the byte addresses 0xaaa and 0x555. It seems to be emulating the behavior of 16-bit addressing while using byte addresses. The mtd driver writes to 0x554, but this usually works, because the A0 bit would be dropped anyway, i.e. it's not connected. What I decided to do was change the scaling factor back to one and let the code directly use 0xaaa and 0x555 instead. This should work, because cfi->device_type isn't used for anything else once the detection and CFI table parsing is finished. I dislike the hack on aesthetic grounds, but it works. A more elegant approach would be to fix up the 0x554, whenever it occurs due to the scaling, but I thought the one-liner was simpler, even if it seems weird. tonyo 氏による Linux kernel へのパッチ diff -C 16 -r /usr/src/olinux/linux-2.6.23/drivers/mtd/chips/cfi_cmdset_0002.c /usr/src/linux/drivers/mtd/chips/cfi_cmdset_0002.c

400円日記における虹野氏の書き込み 10月31日
フラッシュ消去不可
玄箱では問題なく動いているMTDなのに、何故かTeraStationでは読み出しだけで書き
込みが出来ない……。正確には書き込み前の消去が異常終了してるんだけど。
確かにTeraStationのフラッシュメモリは玄箱と違うんだけど、データシートを見る限
り同じコマンドセットなのに、一体何が原因なんだろう？

unlockアドレス
x8 Modeでのunlockアドレスが0x555でなく0x554になってるよ……。これってやっぱり
MTDのバグなのかなぁ。でも、これで MBM29PL32TMはちゃんと動いてるんだよなぁ。
さて、悪いのは誰でしょう？
1. unlockアドレスの生成方法を間違えているMTD
2. 0x554がunlockアドレスと認識されないM29DW324DB
3. 楽する為にCFIを使っている虹野(笑)
とりあえずイレーズに失敗する原因は分かったけど、これどうやって直すかなぁ……。
DTC対応U-Bootの作成 †kernel 2.6.20以降からDTCを利用するようになったので、ブートローダもDTCに対応したものでないといけない。ただし、DTCを利用せずに、以前からの loader.o を使った起動も可能。 2010.03 †標準で DTC に対応している。（というか、EMブートできなくなっている？） netconsole を使いたい場合は、include/configs/linkstation.h を適宜編集すること。 KuroBoxHG/Linkstation HGLANの場合 †$ wget ftp://ftp.denx.de/pub/u-boot/u-boot-2010.03.tar.bz2 $ tar u-boot-2010.03.tar.bz2 $ cd u-boot-2010.03 $ make linkstation_HGLAN_config $ make できあがった u-boot.bin をFlashROM に書き込む。 KuroBox?/Linkstation HDLANの場合 †Ver. 1.1.4 の kurobox.path に含まれていた tulip ドライバ用のパッチが 2010.03 ではすべて抜け落ちていたので、kurobox.path を参考にして、config_HLAN か config_LAN が定義されている場合にそれらのコードが有効になるようパッチを当てたら、FlashROMが富士通 29PL32TM のボードで動いた。FlashROM に ST Micro のM29W320DT や M29DW325DB が使われているボードでは動かないと思うので、注意。 以下が起動画面。 U-Boot 2010.03 (May 29 2010 - 18:52:22) LinkStation / KuroBox
