I2C

VOLTAGE-LEVEL TRANSLATORのPCA9306で、I2Cのレベル変換する。

DIP Switch

スイッチ	意味
Switch 1	onでUSB BOOT
Switch 2	osでSD BOOT
Switch 3	USB HOSTの設定
Switch 4	HDMI SELの設定

インストール

SDカードによるインストール

$ sudo diskutil list

でSDカードのディレクトリを確認する。(以下、SDカードが/dev/disk4だった場合の解説)

$ sudo diskutil unmountDisk /dev/disk4

Unmount of all volumes on disk4 was successful

$ sudo dd if=db410c_sd_install_android.img of=/dev/rdisk4

2048+0 records in
2048+0 records out
2147483648 bytes transferred in 147.654051 secs (14544021 bytes/sec)
      147.68 real         0.00 user         1.86 sys

DragonBoard410にSDカードを差し込み、DIP Switchの2番をONにして再起動する。

Installメニューがあらわれるので、Imageを選択しInstall(i)を選択し、ImageをeMMC(Flashメモリ)にコピーする。

DIP Switchを元どおりにして、再起動する。

Fastbootによるインストール(Debian)

S4のスイッチを押した状態で、電源をONにする。

$ fastboot devices

a4e82d18    fastboot

から、 eMMC用のパーティション生成ツールを取得する。

$ cd dragonboard410c_bootloader_emmc_linux-46
$ ./flashall

eMMC内のデータの削除ができたので、今度は焼き込むイメージを用意する。
