  • Forum Post: DM365 About the memory rate ratio of application

    Tatsuya Ohsawa
    Hi,ALL I use DM365. The memory rate ratio of application was seen by the "top" command. Then, my application( adp_demo ) displayed "102.2". Since it is a ratio, I feel that it is unusual that "102.2" is shown. I think that 100 or less is correct. However, application...

  • Forum Post: Self-Refresh w/256MB of RAM in PM lowest power modes

    Chris R
    Has the self refresh mode for the LPDDR been tested with the full 256MB that's in the newer beagleboards and EVMs? I know that both newer beagleboards and the OMAP-35x EVMs (e.g. Rev.G) have 256 MB of LPDDR on them. Their POP packages use two LPDDR chips that are each 128MB to create the 256MB...

    Michael T
    That amount of memory usage is not unusual and depends on how your system is configured. The following post discusses the amount of memory used by the Linux kernel and has some tips about reducing memory usage: http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/100/p/7946/141479...
