Driver:http://www.ftdichip.com/Drivers/CDM/CDM%20v2.10.00%20WHQL%20Certified.zip

(http://www.ftdichip.com/Drivers/VCP.htm)

Gnd->J1

RX->Pin4

But for me

Gnd->J1

RX->Pin5

Maybe TTL mark is wrong

Putty setting

BBB BB-xm note

150418 note

於BBB上安裝Ubuntu Precise 12.04.4 LTS

http://www.armhf.com/boards/beaglebone-black/


BBB HDMI顯示有問題，無法顯示，但確定有安裝成功



BBB 接Terminal
http://elinux.org/Beagleboard:Terminal_Shells

1.TTL，需購買USB->TTL接板子

2.網路->SSH連線

3.USB連接電腦，走192.168.7.2





於BB-xm安裝Ubuntu Precise 12.04.4 LTS

(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(?))
http://www.htpcbeginner.com/install-gui-on-ubuntu-server-14-04-gnome/

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(?)
