Overview

Real time clock (RTC) is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time. RTCs are present in almost any electronic device which needs to keep accurate time. More general information here.

In IGEP Boards, MPU and PMIC contains each one a RTC clock:

  • System


In IGEP Boards, NFS protocol can be used to mount a whole rootfs partition located in a remote disk like Virtual Machine, this method can be useful for:

  • Your remote rootfs will not be limited by flash or MicroSD storage.
  • You can transfer binaries without using remote connections.
  • You can test other rootfs only editing igep.ini configuration file.

Work under NFS environment has its limitation too:

  • Remote system is a bit slower than a Micro SD or Flash system
  • IGEP X-loader and Kernel will be hosted in Micro SD or Flash
