User Application memory size

@shaul-Kutner I'm not sure I understand your question. The Voxl application processor is running Linux which is a virtual memory system so applications have nearly unlimited memory to use. In terms of non-volatile storage you can see the partitions with the Linux ```df``` command: 
```
/ # df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/root       2.8G  1.9G  906M  68% /
devtmpfs        1.8G     0  1.8G   0% /dev
tmpfs           1.9G     0  1.9G   0% /dev/shm
tmpfs           1.9G  8.8M  1.9G   1% /run
tmpfs           1.9G     0  1.9G   0% /sys/fs/cgroup
tmpfs           1.9G  4.0K  1.9G   1% /var/volatile
/dev/sda2       2.2M   80K  2.0M   4% /persist
/dev/sda3        58M   40K   57M   1% /cache
/dev/sde12       12M  4.1M  7.4M  36% /dsp
/dev/sde11       95M   33M   63M  35% /firmware
/dev/mmcblk0p1   15G  5.6G  8.3G  41% /mnt/sdcard
/dev/sda9        15G  138M   14G   1% /data
```
And for RAM you can check out the Linux /proc/meminfo file:
```/ # cat /proc/meminfo
