BeagleBone Blackを買いました。

http://beagleboard.org/Products/BeagleBone%20Black

シリアルは秋月のFDTI USBシリアルケーブル(3.3V) がぴったりです。
電源はminiUSBで給電して動作しました。



スペック概要は次の表のとおりです。

CPU	AM3359 ARM Cortex-A8 1GHz
Memory	2GB on-board storage using eMMC, 512MB DDR3 (800MHz x 16), microSD card slot
USB	HS USB 2.0 Client Port, LS/FS/HS USB 2.0 Host Port
Video	microHDMI, cape add-ons
Audio	microHDMI, cape add-ons
Supported Interfaces	4x UART, 8x PWM, LCD, GPMC, MMC1, 2x SPI, 2x I2C, A/D Converter, 2xCAN Bus, 4 Timers

購入したのはTechShareで、価格は5,460円 (送料210円) でした。5/11に注文して5/13に到着だったので思った以上に早く到着しました。

NetBSDを動かすわけですが、前のモデルのBeagleBoneのkernelがあるので、それを起動させてみることにしました。

シリアルをつないで起動するとU-bootが起動します。

素早く、enterを押してU-bootのプロンプトに。

FATでフォーマットしたmicroSDにnetbsd.binをロードして、起動します。

root deviceを聞くところまであっさりと起動しましたね。

microSDにファイルシステムを作ってあげれば、さらに先に進めそうな気がしますね。
