回复: [agl-dev-community] About more space for BBE image.

["Yan Xin Kuan" <yanxk.fnst@xxxxxxxxxxx>]

Hi Denys,

Much thanks for this instruction. :)

I think we should fine some other locations to save the temp files, maybe. 

Best,
Yan

主题: Re:  About more space for BBE image.

Hi,

You should know that /run is a tmpfs mounted filesystem, i.e it is a RAM-disk. 
Which means it is not a storage limitation, but rather a memory limitation, as BeagleBone and BBE only have 512 MB of RAM on board.

If you need to stora large amounts of data, you need to change the location and point to a storage-backed filesystem, which could reside on an SD card or USB-mounted hard drive.
