I am using Apalis iMX6Q on an Apalis Evaluation Board and I am trying to generate a tezi-compatible image.
I successfully build an image that I could write on a SD card and everything was well until “I” discovered the need to use the eMMC and from here the party started.
There would’ve been no problem whatsoever if I didn’t need to have a custom kernel (based on a quite old one - 4.19) on my system.
I tried to add in local.conf:
IMAGE_CLASSES_append = " image_type_tezi"
PREFERRED_PROVIDER_virtual/kernel = "linux-customed"
include conf/machine/include/${MACHINE}.inc
and in custom-image.bb
# Show Tezi EULA license
TEZI_SHOW_EULA_LICENSE ?= "1"
TEZI_SHOW_EULA_LICENSE_apalis-tk1 ?= "0"
TEZI_SHOW_EULA_LICENSE_use-mainline-bsp ?= "0"
TEZI_SHOW_EULA_LICENSE_colibri-imx6_use-mainline-bsp ?= "1"
TEZI_SHOW_EULA_LICENSE_apalis-imx6_use-mainline-bsp ?= "1"
IMAGE_CLASSES += "image_type_tezi"
IMAGE_FSTYPES_append = " teziimg"
PREFERRED_PROVIDER_virtual/kernel = "linux-customed"
I know I have some redundancy here but this is not the problem. The real problem is that building now (after these changes) I SOMEHOW end up with the mainline kernel (5.4.193)
I have tried to comment from local.conf
include/conf/machine/include/${MACHINE}.inc
This gets me this error:

I also tried to leave the include/conf/machine/include/${MACHINE}.inc from local.conf and modify conf/machine/include/apalis-imx6.inc as:
MACHINE_NAME = "Apalis-iMX6"
KERNEL_DEVICETREE += "imx6q-apalis-ixora-v1.2.dtb"
KERNEL_DEVICETREE_use-mainline-bsp += " \
imx6q-apalis-eval.dtb \
imx6q-apalis-ixora-v1.1.dtb \
"
[...]
#PREFERRED_PROVIDER_virtual/kernel = "linux-toradex"
PREFERRED_PROVIDER_virtual/kernel = "linux-customed"
#PREFERRED_PROVIDER_virtual/kernel_preempt-rt = "linux-toradex"
PREFERRED_PROVIDER_virtual/kernel_preempt-rt = "linux-customed"
PREFERRED_PROVIDER_virtual/kernel_use-mainline-bsp = "linux-toradex-mainline"
PREFERRED_PROVIDER_virtual/kernel_use-mainline-bsp_preempt-rt = "linux-toradex-mainline"
PREFERRED_PROVIDER_virtual/dtb_use-mainline-bsp ?= "device-tree-overlays-mainline"
[...]
but I still end up with the mainline kernel.
Any ideas on how can I make it work please? it drives me nuts
