额，遇到了新问题。 我是用4g的卡烧写的2g的debian镜像。根据提示 装 sudo apt-get -y install lxde lxde-core lxde-icon-theme   的时候，发现储存空间不够。想请教一下 ，怎么样把另外2g的剩余空间利用起来？  

通宵敲代码 发表于 2014-11-5 17:37 刷一个集成了桌面的系统就可以。

我刷的是 http://www.beagleboard.org/latest-images 里面的 Debian (BeagleBone, BeagleBone Black - 2GB SD) 。用vnc能够看到桌面。 但是装上LCD的时候，能够调到登入界面，然后似乎是自动登入的，然后就跳出 touchscreen calibration for “ti-tsc”的界面，再怎么点屏幕也没用，过了一会儿，就变成整个LCD的左上角出现跳动的光标，其他地方都是黑色的。 用SSH登入，可以的，说明系统应该是启动的。就是不知道怎么在LCD上显示出系统的桌面。

知不知道屏幕点亮后，怎么显示桌面系统啊？  

怎么弄就是启动不了屏幕额，请大家帮忙看看是什么原因。 U-Boot 2014.04-00014-g47880f5 (Apr 22 2014 - 13:23:54) I2C:   ready DRAM:  512 MiB NAND:  0 MiB MMC:   OMAP SD/MMC: 0, OMAP SD/MMC: 1 *** Warning - readenv() failed, using default environment Net:    not set.

版主，按照你的原理图做了LCD的板子，也修改了uEnv.txt 但是还是不能在lcd上有显示，是需要从sd卡启动才行的么？

版主，有没有多余的LCD板子，可以出售啊？

版主，LCD cape有卖么？  想入手一块。

学习一下。。。

期待 Eclipse 在线调试BBB
