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.

Here is the kernel version and android version:

Hi Qingyuan

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

supports up to 4.4.
