The board memory for 128M CPU is S3C2416
To copy files, as long as the file size is less than 20M can copy. If you copy files larger than 20M will appear the following information. The system then died.. Everybody have a look what it is? ? ? ?

You can have a look how much free, memory available.

Is it right? You are copying the file to the memory, then there is not enough memory available, cause this problem.

There are free, memory left a half.. Use the top command to see, the process CP can only occupy memory 3.4%. .
