Time out check load galcore module expired

whay are we getting this, how to fix this, ?

[Olivier GALLIEN]

Hi @Ara.1​ 

You are giving too few informations about your setup and application to provide pertinent answer.

Please add further detail about what you are doing.

which board ? Custom build ? from Distri, Developper pack etc...

Thx

Olivier

Complete boot log and traces around galcore failure is also a must

Hi Olivier,

attached is the current log,

I did rebuild all my custom image once again from wiki st link steps followed, the distro is openst-weston-wayland.

now i can able to see Galcore getting probed.

how can i test STM32MP1 GPU/galcore.ko functionality ?

Hi,

you need the mesa library which will use the galcore driver.

I have also encountered this problem, which has bothered me for a long time. Can you describe the solution in detail? Thank you very much! The first picture is the normal startup log, and the second picture is the uimage startup log compiled by myself. It may be certain that the problem is in galcore which makes many modules and functions unusable.

I make a try just now, and now it works.

It's not enough to compile the kernel, you also need to compile the module. And you must follow the steps on the wiki.

But "Time out check load galcore module expired" still exits, which results in the USB network card and screen restart. This is too bad.
