iMX6 - Galcore driver stops the boot imx6 sabrelite

[abrahim]

Hi,

I'm using the defaut kernel 5.10.72 with imx_v6_v7_defconfig, with imx6dl-sabrelite device tree.

When I disable GPU vivante driver it works, otherwise, the boot stops with a kernel panic :

Hello,

The error is due to kernel, you have to build and deploy it right since you have a kernel panic it means that something not build correctly.

No because when I disable the Vivante GPU driver it works, so it has nothing to do with the way I compile or flash. 
By the way I have a sabrelite 

best regards,
