Hi @cgsasse !

@cgsasse

Can you tell us how we can get the kernel to load the fbtft module much earlier?

Did you build the driver as builtin or as module? As built-in, it will probably start working much sooner.

You can refer to this thread where Jeremias explains how to modify TorizonCore’s kernel configuration in Yocto:

Steps to modify the kernel for TorizonCore

So just to verify, does this link have everything I need to set this variable? Well it doesn’t spell out this exact scenario. But the general steps are there on how to create a patch or config file for out kernel and build it in Yocto. For a more “real” example you can see the recipe for our kernel recipe here: linux-toradex_5.15-2.1.x.bb « linux « recipes-kernel - meta-toradex-nxp.git - Toradex BSP layer, recipes for NXP based modules In this recipe we add some PREEMPT RT related kernel con…

Also, here is Yocto’s documentation (kirstone verison) about Kernel Cache:
