WR8750N fixed-regulatorメモ

WR8750N/WR9500N/WG600HPではいくつかGPIOをHIGHで出さなければ機能しないデバイスがあり、それらについてfixed-regulatorのDeviceTree binding (compatible = "regulator-fixed") を使用する場合の挙動確認用メモ。

USB-Vbus
ath79内の他のdtsでは問題無いようではあるものの、Aterm 3機種ではブート中に無効化されてしまった。こうなると、USBポートにDC 5V電源が供給されずデバイスが使用できない。
ノード内に regulator-always-on; を付加した場合は無効化されず有効なまま。

WR8750Nメモ　U-Boot & OpenWrt

Aterm WR8750NのNECオリジナル (?) なBootloaderを、musashino-build/u-boot_modからビルドしたU-Bootに置き換えてブートしたログのメモ。
上記リポジトリからのビルドはWSLで問題無く行えた。
全体的な流れとしては以下の通り。

  • NECのBootloader上でOpenWrtのNEC用initramfsイメージ (initramfs-necimg) をPCから転送し、boot コマンドを実行してOpenWrtをブート
  • initramfs上でU-Bootパーティション内を mtd erase u-boot で消去し、scp等で転送しておいたU-Bootを mtd write ファイル名 u-boot で書き込み
  • wget等でダウンロードしたOpenWrt sysupgradeイメージを sysupgrade ファイル名 でFlashへ書き込み
  • reboot で再起動し、U-BootによりOpenWrtが起動される

WR8750N Bootloader書き戻しメモ

U-BootからNECのBootloaderへ書き直したメモ。昨日はSOP16のクリップでSPI-NOR Flash読めたのに今日は全くダメだったので、諦めて他の方法を探って辿り着いた。
書き戻しに失敗したらどうにかFlashを直接書き換えなければならなくなるので、非常に怖い。

LAN-W451NGR & OpenWrt

MACアドレスが独自フォーマットで格納されているなど、色々と厳しいのでupstream (openwrt/openwrt) へ投げるのはやめました。そのため、musashino-build/openwrtで持つだけになります。
以下OpenWrtインストール手順。

UARTを接続
LAN-W451NGRの筐体を開けてUART（シリアル）を接続。ピンは最初から立っていた。
並びは RJ-45ポート側から Vcc, TX, RX, GND。
U-Bootの環境変数を変更
ブートを中断してU-Bootのコンソールに入り、bootcmd の変更とMACアドレス設定の追加を行う。
bootcmdは以下の通り変更する。

set bootcmd "bootm 0x9f0a0010 || bootm 0x9f0a0000"


MACアドレスは筐体のラベルを参照し、以下の通りに変更する。

set wanaddr "MAC address"


例（MACアドレスが 00:aa:bb:cc:dd:ee の場合）

set wanaddr "00:aa:bb:cc:dd:ee"


最後に saveenv を実行して変更を保存。

initramfsファームでブート
192.168.1.50でTFTPサーバを実行して 0201A8C0.img にリネームしたinitramfsファームを用意し、コンソールで tftppboot（tftpでも可）を実行してinitramfsファームをTFTPサーバからダウンロード、bootm を実行してinitramfsファームによるブートを行う。
ブート後、mtdパーティションのバックアップを取っておくと良い。
sysupgrade
initramfsファーム上でsysupgradeファームを用いてsysupgrade、完了して再起動され、Flash内のOpenWrtファームウェアで起動する。

以上。

WR8750Nメモ(5) OpenWrtとWDT

前回の記事の続きの様なもの。

WR8750NではBootloaderがWDTに設定する制限時間が短いためにOpenWrtのLinux Kernelを起動する際にWDTドライバをロードするタイミングが間に合わない。
なのでOpenWrtのLZMA-LoaderをBootloaderから最初に開始させ、board_init() でAR9344のWDTレジスタのカウントを最大値に設定したうえでLZMA圧縮のKernelを展開、実行を渡して開始するようにした。
なお、LZMA-Loaderのコンパイル時に CONFIG_BOARD_ボード名 を構成するために必要なコードが ath79/image/Makefile に1行不足していたため、付け足した。

ath79/image/lzma-loader/src/board.c

tlwr1043nd_init()と同様に、最後にREADREGした方が良いのだろうか。

#ifdef CONFIG_BOARD_WR8750N
static void wr8750n_init(void)
{
	unsigned int reg = KSEG1ADDR(AR71XX_RESET_BASE);
	unsigned int t;

	t = 0xfffffffful;
	WRITEREG(reg + AR71XX_RESET_REG_WDOG, t);
}
#else
static inline void wr8750n_init(void) {}
#endif

void board_init(void)
{
	tlwr1043nd_init();  // 別途あるTL-WR1043ND用コード
	wr8750n_init();
}

ath79/image/Makefileの追加部分

	$(MAKE) -C lzma-loader \
		PKG_BUILD_DIR="[email protected]" \
		TARGET_DIR="$(dir $@)" LOADER_NAME="$(notdir $@)" \
+		BOARD="$(BOARDNAME)" \
		LZMA_TEXT_START=0x80a00000 LOADADDR=0x80060000 \
		$(1) compile loader.$(LOADER_TYPE)
	mv "$@.$(LOADER_TYPE)" "$@"

WR8750Nメモ (4) ブート関係

ツイートに複数の方から「Watchdog Timerではないか」という指摘を頂き、DTSでwdtノードを無効化するもダメ。レジスタを確認し、試しに制限時間経過時のアクションを “No action” に設定したところ、すんなりと起動できた。
恐らく、Bootloaderが設定するWatchdog Timerの制限時間に、OpenWrtのLinux KernelがWDTドライバを初期化し応答できる状態になるタイミングが間に合っていない。対処法はぼんやりと考えているので後で試す。

サポート作業状況（2018/12/17時点）

動作OK

  • initramfsファーム
    • kernelとrootfs等の構成等については考え中のため、sysupgradeファームはまだ
  • Ethernet
  • WLAN 2/5 GHz
    • Kernelからの認識のみ確認
  • LED
    • 10個全てAR9382 (ath9k)が持つ
  • ボタン, スライドスイッチ

作業中

  • sysupgradeファーム
  • Factoryファーム
  • USBポート
    • NECの4ポートハブチップが接続されているものの、何故かFull-SpeedでSoCと接続されてしまう。原因不明。

メモ

  • NECのハブチップの電源（あるいは有効化？）にはath9kのGPIO10、USBの物理ポートの電源にはSoCのGPIO19か20辺りが絡んでいる模様。
