On ARM Versatile Express A9 board with Linaro Android image:
https://android-build.linaro.org/builds/~linaro-android/vexpress-linaro-13.10-release/#build=2
SD Card directory is unavailable after ADB file transfer. The procedure list is:
1. Establish ADB connection over Ethernet;
2. From host machine, using "adb push" to transfer any file to path "/sdcard"
3. On target serial console, run "cd /sdcard"
Then the error shows:
root@vexpress:/data # cd /sdcard
/system/bin/sh: cd: /sdcard: Not a directory
2|root@vexpress:/data #
The file can be transferred successfully from host machine side, but can't be found under /sdcard
A reboot can eliminate this issue, though the transferred file is still missing. And the "/sdcard" can also be accessed before the file transfer.
Also, here is the output of "df" and "mount" from my board:

Can you try pushing files to /mnt/sdcard which is the right place to push the files.
