Using scartgap branch, trying to create a kernel recipe for a custom
LS1028 machine.
The recipe in meta-freescale for the ls1028ardb is hopelessly outdated and
produces a 5.10 kernel.
So for my custom board based on the ls1028 I want to create a recipe that
builds a mainline kernel (I don't need GPU or fancy things that require
firmware or special drivers, so mainline should be fine).
I started out trying to get linux-yocto to build for my board, so copied
the "skeleton" recipe, adjusted a bit (add COMPATIBLE_MACHINE and a
defconfig).
But when I then run "bitbake -c menuconfig virtual/kernel" I always get
this message:
ERROR: linux-yocto-*-6.6+git-r0 do_menuconfig: do_menuconfig is disabled,
please check KCONFIG_CONFIG_ENABLE_MENUCONFIG variable.
I tried starting with a copy of recipes like linux-fscl, same error. Always.
(note: I've run "menuconfig" a million times by now, for dozens of boards,
so it's not the system).
I tried adding
KCONFIG_CONFIG_ENABLE_MENUCONFIG="true"
to my recipe, but that also had no effect.
The log file also contains no information whatsoever.
What's the real issue?
cml1.bbclass has this:
KCONFIG_CONFIG_ENABLE_MENUCONFIG ??= “true"
…
if not bb.utils.to_boolean(d.getVar("KCONFIG_CONFIG_ENABLE_MENUCONFIG")):
bb.fatal("do_menuconfig is disabled, please check
KCONFIG_CONFIG_ENABLE_MENUCONFIG variable.”)
So if you’re seeing that message then _something_ is assigning that
variable to false. Use bitbake-getvar to identify what that is.
Interesting, that points to "uboot-config.bbclass:147" which sets it to
false. I'm not building u-boot here, I'm building the kernel?
$ bitbake-getvar -r linux-fslc KCONFIG_CONFIG_ENABLE_MENUCONFIG
#
# $KCONFIG_CONFIG_ENABLE_MENUCONFIG [3 operations]
# set /.../oe-core/meta/classes-recipe/cml1.bbclass:35
# [_defaultval] "true"
# set uboot-config.bbclass:147
[__anon_148__..._oe_core_meta_classes_recipe_uboot_config_bbclass]
# "false"
# set uboot-config.bbclass:147
[__anon_148__..._oe_core_meta_classes_recipe_uboot_config_bbclass]
# "false"
# pre-expansion value:
# "false"
KCONFIG_CONFIG_ENABLE_MENUCONFIG="false"
This is because of using "fitImage":
meta/classes-recipe/kernel-fitimage.bbclass:inherit kernel-uboot
kernel-artifact-names uboot-config
I can specify this in the kernel recipe to make this error go away:
UBOOT_CONFIG = "tfa"
But then the menuconfig command just exits silently and does nothing whatsoever.
So the issue turns out to be that setting KERNEL_IMAGETYPES = "fitImage"
breaks menuconfig for the kernel in the scartgap branch.
Only way I've been able to run menuconfig is to temporarily change
KERNEL_IMAGETYPES to something else, then do the kernel configuration and when
done change it back again.
