Contributor I

Dear all,

     I have a strange problem need your help, it was about the EMMC4.5 support

in imx508 android system.    

     It will show below errors every times when the devices bootup from emmc4.5:

     [   10.863246] init: untracked pid 1882 exited

     [   10.883744] init: untracked pid 1886 exited

     [   10.887970] init: untracked pid 1979 exited


    Do you know why?How can solve this issue?


Here is the reproduce step:

   1.Use the "MfgTool.exe" to update the firmware;

   2.Reset the devices,then bootup the device,it was the first time bootup,in this bootup,it can't appear this problem;

   3.Poweroff the devices,then bootup again,it was the second times bootup,it will appear this problem;

   4.From now,it will appear this problem in every times bootup.

Hi Qingyuan

i.MX50 ESDHC hardware does not support eMMC4.5,

supports up to 4.4.

Best regards
