Dear Toradex and everyone,
I want to update the default kernel’s version used in Buildroot to newer one which is rel_imx_4.9.x_1.0.0_ga from https://git.toradex.com. Can you tell me if I can use this version for my Apalis-iMX6 module and which defconfig and DTB should I use? ( imx_v6_v7_defconfig, imx6q-apalis-ixora.dtb respectively seen from Apalis imx6 Mainline Kernel Compilation - Technical Support - Toradex Community )
Thanks and best regards,
I gave a quick trying to compile this kernel’s version but had some problem as following :

I think toradex_4.9-2.3.x-imx (which has the apalis_imx6_defconfig) can be used for Apalis-iMX6 module instead. I could build it successfully with imx6q-apalis-eval, imx6q-apalis-ixora DTBs.
The following article on our developer website outlines what exactly to use:
Please note that rel_imx_4.9.x_1.0.0_ga is definite not one of the supported versions.
