I'm trying to get swupdate working with dual copy mode on my jetson nano devkit.
My setup so far is like this:

My custom partition layout is:

I have a recipe swupdate-image.bb, which is in part copied from here: https://github.com/madisongh/tegra-test-distro/blob/dunfell/layers/meta-testdistro/recipes-testdistro/images/swupdate-common.inc

SUMMARY = "SW Update Image"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

SRC_URI = "\
    file://sw-description \
    file://swupdate-bl-update.sh \

IMAGE_DEPENDS ?= "fl2-base-image"
SWUPDATE_IMAGE_NAME = "fl2-base-image"
SWUPDATE_IMAGES = "fl2-base-image"
SWUPDATE_IMAGES_FSTYPES[fl2-base-image] = ".ext4.gz"

inherit swupdate

And a sw-description also copied from the test-distro:

software =
{
	version = "@@DISTRO_VERSION@@";
	hardware-compatibility = [ "1.0" ];

	system =
	{
		slot_a:
		{
			images: (
			{
				filename = "@@SWUPDATE_IMAGE_NAME@@-@@MACHINE@@.ext4.gz";
				type = "raw";
				compressed = "zlib";
				device = "/dev/mmcblk0p2";
				installed-directly = true;
			});
			scripts: (
				{
					filename = "swupdate-bl-update.sh";
					type = "postinstall";
					data = "/dev/mmcblk0p2";
				});
			bootenv: (
			{
				name = "BOOT_ORDER";
				value = "b a";
			},
			{
				name = "BOOT_b_LEFT";
				value = "3";
			});
		}
		slot_b:
		{
			images: (
			{
				filename = "@@SWUPDATE_IMAGE_NAME@@-@@MACHINE@@.ext4.gz";
				type = "raw";
				compressed = "zlib";
				device = "/dev/mmcblk0p1";
				installed-directly = true;
			});
			scripts: (
				{
					filename = "swupdate-bl-update.sh";
					type = "postinstall";
					data = "/dev/mmcblk0p1";
				});
			bootenv: (
			{
				name = "BOOT_ORDER";
				value = "a b";
			},
			{
				name = "BOOT_a_LEFT";
				value = "3";
			});
		}
	}
}

I build a .swu file using bitbake swupdate-image.
I copy this file to my device and run swupdate -e "system,slot_a" -i ./update.swu.

But I get:

[INFO]: SWUPDATE started: Software Update started!
[ERROR]: SWUPDATE failed [0] ERROR: bootloader support absent but sw-description has bootloader section!
[ERROR]: SWUPDATE failed [0] ERROR: Compatible SW not found
[ERROR]: SWUPDATE failed [1] Image invalid or corrupted. Not installing...
[INFO]: No SWUPDATE running: Waiting for requests...

I don't know where to go from here and need some hints.

Sounds like you didn't build swupdate itself with the right configuration - it can't find a handler for U-boot support. Did you also copy over the bbappend and config files from the test distro?

I'm not getting any errors anymore, but I'm still booting into into mmcblk0p1.
My UART u-boot output:

I'm not seeing the root= or rauc.slot= settings in the kernel command line append that U-Boot is making. Do you have this in your U-Boot build, and did you re-flash your Nano to get the updated U-Boot programmed into the SPI flash?

Achder Nov 11, 2021

I created a u-boot-tegra_2020.04.bbappend under mydistrolayer/recipes-bsp/u-boot-tegra with:

SRCREV = "14b16137af48979270d096efbd209b74b03d2627"

FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"

SRC_URI += "file://0001-Modify-distro-boot-script.patch"
SRC_URI += "file://rauc.cfg"

KERNEL_ROOTSPEC = "root=PARTLABEL=${bootpart_label} rootwait"
UBOOT_EXTLINUX_ROOT:append = " rauc.slot=${bootslot}"

With the 0001-Modify-distro-boot-script.patch, fw_env.config and the rauc.cfg files in the ${PN} subdirectory. I build the image, unpacked the tegraflash and flashed the SPI flash using doflash.sh --spi-only.

I'm a bit confused by the rauc.slot=. Can you expain what it does? And does it apply when using swupdate?

It indicates which slot was selected. Looking over the implementation in my test distro, I guess I don't actually use it with swupdate, just RAUC (which requires it). As long as the root= is getting inserted, so the initramfs startup script knows which partition to mount, and you have a script like this one that can inform swupdate which slot you're currently running from, I guess you don't need it.

Check the /boot/extlinux/extlinux.conf file in the image that got built, though, to make sure the APPEND line includes at least the root=... text. From one of my Nanos:

APPEND ${cbootargs} root=PARTLABEL=${bootpart_label} rootwait rauc.slot=${bootslot} ${bootargs}

It's working now!
I didn't change anything after my last post. I must have used an old image or forgot a bitbake.
Thanks so much for your patience and your help!
