I don't think this is a correct solution, or maybe I'm not understanding the
problem. Can you please elaborate a bit more on the problem?
I'm fairly new to yocto so I'm sure I've found the entirely wrong way to
get what I wanted :)
After boot it appears /etc/fstab is setup to mount our vfat boot
partition to the /boot directory currently holding the Image and dtbs.
I guess because uboot has already thrown the kernel and dtb into ddr at
this point only Anand was able to notice this.
My change should mount the vfat partition to /boot/firmware so we can
access to both our spls and kernel binaries in /boot.
I'm also not sure what folder name to use here. It seem like there may
be a standard to this? Would /boot/uboot be more correct?
So which SoCs are we talking about here? For the 64bit parts, the
intention should be that the FAT partition on p1 be functional as the
ESP. So that means mounting it to /boot/efi. But I'm not sure off-hand
how that's being treated in upstream OE around the notion of making an
image that's what a UEFI system expects.
Ideally this should be for all TI's K3 devices. I'm unfamiliar with the
UEFI format and don't know if we currently follow it, however I like the
idea of /boot/efi from what I googled. I also found raspian is using
/boot/firmware. Could this be less of a standard than I think?
Keep in mind this is a generic OE on 64bit Arm problem and not a TI
specific problem. Where to mount the ESP should have a consistent
default. And it should look like it does on an off the shelf distro.
While not an exact ESP partition, we are working on making our boot
partition as close as we can given ROM constraints.
I'm running into the problem now of updating kernel on a live system,
would fail as we have mounted our boot partition over the rootfs boot/
directory, so new images are not installed to the right spot/partition.
Let's go with /boot/efi if that works for everyone.
Bryan, could you re-send this with that change and the same for
sdimage-2part-efi.wks.in?
The only feedback I would provide here is to work with the ROM team to
fix whatever constraints prevent an "ESP" itself from being used as this
will hinder the long term viability of the processors being widely
supported.
Haha, this debate has lasted so long that systemd-boot has standardized
mounting the ESP partition to just /efi now [1].
