WinEC7 boot time RRS feed

  • Question

  • Hi Friends,

    I'm currently working on a iMX53 based board which is under design,

    We have chosen  to port WinEC7 on it.

    I'm doing a analysis on boot time calculation.

    Does anyone have idea about the boot time of Eboot + winEC7 on iMX53 or any platform????

    please give your valuable info,  which would be helpful for my analysis....

    Thanks in Advance,

    Mani

  • Boot time directly deals with following :

    1. Size of the NK.bin, which means the number of components added to the image build.

    2. Clock speed or the speed with which you will download the image to the RAM before launching it.

    3. MultiBinFS support -> Technique used to speed booting.

    There are other things to optimize the booting process :

    1. Delay during driver loading. (sequential loading of driver)

    2. Delay during file system mounting.

    3. Analysis of system boot using celog and platform builder debugging tool and fixing the boot delay.

    Are you using NAND or SD Card to boot your system ?

    I can give you a figure ... For 70MB image with NAND boot, the device boots in the of 20 sec of cpu clock 720Mz (It is not the best case, the best case can be achieved following the above points)

  • We have planned to use NOR for boot.

    atleast it would save some seconds.

    Will update you with more douts :)
