Galaxy note n8010 tossing logs can be used. Installed ssh server (quickSSHd), with the computer ssh (ssh root@192.168.; 0.102) in the past unexpectedly found that there is no cp command. Immediately compiled a busybox (compilation steps: make menuconfig, set cross toolchain, and then make; make install), with scp (scp-r _ install root@192.168.0.102 :~) Pass in.

The most direct way to become a lazy is to make menuconfig to Remove mount. * If the pad is sleep, the ssh terminal responds very slowly.

It is used to put boot, kernel, file system, and other root @ android: /mnt/sdcard # df-hFilesystem Size Used Available Use % Mounted ontmpfs 910.2 M 84.0 K 910.2 M 0%/devtmpfs 910.2 M 0 910.2 M 0%/mnt/asectmpfs 910.2 M 0 910.2 M 0% /mnt/obb/dev/block/mmcblk0p9 1.3G 1.2G 185.4 M 87%/system/dev/block/mmcblk0p12 11.8G 4.6G 7.1G 40%/data/dev/block/mmcblk0p8 787.4 M 13.4 M 774.0 M 2%/cache/dev/block/mmcblk0p3 19.7 M 4.4 M 15.3 M 22%/efs/dev/fuse 11.7G 4.6G 7.0G 40%/mnt/sdcard
