FWIW, I don't think /boot is required. bootstd/bootmeth in U-Boot (upstream
at the very least) will check for / and then /boot prefix for the paths in
extlinux.conf. Not providing /boot means if someone still wants to use a
separate boot partition, they wouldn't have to update this variable. But
since it's overridable, this is basically up to your preference.
This is a good example of working ahead. The next thing I have queued up is
a meta-rauc-rockchip example that works generically on all (most?) rockchip
boards. As part of the U-Boot script I need to make the A/B logic work, it
needs the "/boot" in there otherwise it doesn't work; therefore it's best to
set it up properly now.
Mmmm I'm interested to see why it fails without the /boot thing? Let's
see when we get patches :)
+UBOOT_EXTLINUX_LABELS ?= "default"

+MACHINE_ESSENTIAL_EXTRA_RRECOMMENDS += "u-boot-extlinux"
Is the image actually bootable if we do NOT have u-boot-extlinux installed?
I'm challenging the RRECOMMENDS basically. And wondering whether
MACHINE_ESSENTIAL_EXTRA_* is always included (it seems like RDEPENDS one is
part of packagegroup-core-boot which is virtually installed in all images).
I can double-check, but I'm pretty sure that line was added explicitly after
testing and noticing that it was needed. If we remove the extlinux artifacts
from the image, what boot method is U-Boot supposed to use?
I'm not saying it is not needed, I'm thinking _RRECOMMENDS is too weak
and it should be _RDEPENDS instead?
I'm not sure the wic image (or rather the rootfs) is proper basically if
u-boot-extlinux is not installed.
As for what U-Boot does if it doesn't find an extlinux.conf, it depends
on what U-Boot is configured to do. If I rememebr correctly, most (all)
Rockchip boards now use bootflow by default.
You can check the content of the bootcmd environment variable, that's
what's started when the user does nothing to interrupt the boot.
For me on Jaguar RK3588:
"""
> printenv bootcmd
bootcmd=bootflow scan -lb
"""
remove the -b flag so it doesn't boot and you should have something
reasonable.
For me:
"""

"""
The media tested seems to be located in boot_targets, which defaults for
that board to:
"""
> printenv boot_targets
boot_targets=mmc0 mmc1 nvme scsi usb pxe dhcp spi
"""
So it tries to boot from mmc0 (eMMC usually), mmc1 (SD card usually),
nvme, scsi, usb, pxe (glorified TFTP?), dhcp, spi.
So if nothing works/exists before scsi, then it'll try to boot from
that, then USB, then from the network and finally maybe from spi but
that is very likely to fail as well since SPI flashes are typically very
small and wouldn't be able to contain even the kernel Image?
This is actually quite nice, I was wondering also if there was a way to
create as many entries as there are Device Trees supported for the machine
(and maybe even device tree overlays? but this one's difficult because we
need knowledge of which device tree overlay can apply on top of which device
tree(s) :) ). But I don't think we can have anonymous python in conf file?
Or maybe we should do this in u-boot bbappend?
Yes. The bbclass has logic to generate as many entries as user-supplied labels
in UBOOT_EXTLINUX_LABELS:
https://git.openembedded.org/openembedded-core/tree/meta/classes-recipe/uboot-extlinux-config.bbclass#n114
I actually hint at the mechanism my providing the superfluous ":default"
entry.
I'm actually more discussing how to *feed* this to this part of the
code. Right now, this is manual because we need to define labels and for
each variable a label override.
I was wondering if we could have something that automatically creates
labels for the non fitimage usecase, based on the KERNEL_DEVICETREE
variable.
in pseudo code:
UBOOT_EXTLINUX_LABELS ?= ""
python __anonymous() {
UBOOT_EXTLINUX_DEFAULT_LABEL = first(KERNEL_DEVICETREE)
for devicetree in KERNEL_DEVICETREE:
UBOOT_EXTLINUX_LABELS += basename(devicetree)
UBOOT_EXTLINUX_FDT:basename(devicetree) = devicetree
}

Does the WKS file still really depend on virtual/kernel or is it rather a
misplaced dependency now?
Great catch! Also, since all the partitions now have explicit fstypes, and the
fact we no longer have a vfat-formatted /boot partition, the mtools-native and
dosfstools-native dependencies can also be removed.
It will probably get rejected, but I think I'm going to create a patch for wic
that assumes unspecified partitions are "none" instead of "vfat". I wonder how
many BSP layers are copy&past'ing the mtools and dosfstools dependencies that
aren't using vfat-based partitions and wondering why?
And a nice catch from you there too :)

Quentin
