Hi,

I am using i.MX8M custom board with linux 4.9.51_ga release. I am using custom built kernel images.
Here below error prints are seen while booting.

**************************************
[ OK ] Started Network Time Synchronization.
Starting Load Kernel Modules...
[ OK ] Reached target System Time Synchronized.
[FAILED] Failed to start Load Kernel Modules.
See 'systemctl status systemd-modules-load.service' for details.
[ OK ] Reached target System Initialization.
[ OK ] Listening on dropbear.socket.
**************************************

If the content of the file '/etc/modules-load.d/galcore.conf' is commented in rootfs, then the issue gets solved.

Kindly let me know the reason for this error print.

Thanks in advance,

Best Regards,

Yashavantha

Correct Answer

Kernel .config file changes in Yocto build and standalone build. So if standalone built kernel images are used the above error will appear. Made kernel config file same as the one which is available in yocto build to solve the issue.

See the reply in context

Hi Yashavantha,

You are accessing graphics in your project, that´s you need galcore

Hi Bio_TICFSL,

Thank you for reply.

But may I know,why EVK doesn't have this error? Our yocto building procedure is as same as EVK.

Hi,

I am facing the same problem -> [FAILED] Failed to start Load Kernel Modules.

[Kernel version 4.9.88_2.0.0_ga]

I need to use the GALCORE driver since my application is a GPU application. Currently no drivers are being loaded. "lsmod" gives empty list.

I am building the kernel image using standalone approach.

Could you please let me know how this could be resolved?

Regards

Vinay

Should rebuild, if you change the kernel, the md5 is changed, and gcore driver module can not be installed , which direct this problem~
