(無法安裝，網站資料已刪除)



Ubuntu Precise

安裝後並無GUI介面

安裝 ubuntu GUI介面(sudo apt-get install ubuntu-desktop)，BBB會跑不動，要使用較輕量化的


Ubuntu Precise 12.04
安裝xubuntu 可用，順暢度還ok


Ubuntu Precise 14.04
GUI介面

Ubuntu Unity Desktop(會當機(?))

Gnome classical(安裝後無法開啟(?))

使用Jessie Snapshot lxqt
Flasher: (lxqt-4gb) (BeagleBone Black 4GB eMMC)
介面太簡潔，無內建網路功能


BBB SPI

Enable sSPI0

In echo BB-SPI0-01 > /sys/devices/bone_capemgr.*/slots

Permission denied

solved:using sudo -i and go echo BB-SPI0-01 > /sys/devices/bone_capemgr.*/slots

Don't using sudo echo BB-SPI0-01 > /sys/devices/bone_capemgr.*/slots

--ls -al /dev/spidev

已出現，但重開機後消失

uEnv.txt 增加的指令未執行 (optargs=quiet drm.debug=7 capemgr.enable_partno=BB-SPI0-01)

log訊息顯示HDMI依然與SPI0衝突(?)
