Free RAM on Colibri VFxx in Linux

How much RAM is available on Colibri VFxx with the standard Linux image running?

For Vybrid we offer two standard images:

  • Colibri_VF_LinuxImage…: An image with X-Server and a LXDE based desktop
  • Colibri_VF_LinuxConsoleImage…: A console-only image

Needless to say, the LXDE image standard memory usage is higher than the console only. Just checked the numbers with our latest release V2.6 Beta 2, this is the default usage by the kernel and user space:

  • Colibri_VF_LinuxImage…: 11296K reserved by the kernel + 30096K used by the system
  • Colibri_VF_LinuxConsoleImage…: 11296K reserved by the kernel + 10728K used by the system

The system also buffers/caches some files which would get freed up when allocating the memory, plus it requires some memory for house keeping which is not yet part of the numbers above. You typically end up with this numbers reported to be available (according to free):

        Console Image             LXDE Image
VF50            ~96MB                  ~76MB
VF61           ~226MB                 ~204MB
