I support!
I am currently working on an update to the yocto version with mender support.
Honister starting version towards scarthgap.
I need to keep the same layout (same sizes between APP, APP_b and UDA) so that my mender images can work on products already deployed for years and are compatible with SKUs 301 and 302.
# NOTE:
# These values are pinned to maintain backward compatibility with SKU 301 devices
# originally deployed with Honister-based images.
# Changing them would break OTA updates and rollback for existing devices.
So I configure with the same sizes
local.conf
# Enable Mender logic for this build
INHERIT += "mender-full"
INHERIT:append:tegra = " tegra-mender-setup"
MYPRODUCT_MENDER_ENABLED = "1"
# Conditionally include Mender-specific providers
require conf/distro/include/myproduct-mender-preferred.inc
# Enable redundant root filesystem layout (A/B) to support atomic OTA updates with Mender.
# This switches the partition layout template to the *_rootfs_ab.xml version,
# ensuring the presence of both APP and APP_b partitions.
USE_REDUNDANT_FLASH_LAYOUT = "1"
myproduct-mender-preferred.inc:
# Adjust reserved space for APP/APP_b so UDA has room
TEGRA_MENDER_RESERVED_SPACE_MB = "1974"
# Allocate a larger persistent data partition
MENDER_DATA_PART_SIZE_MB_DEFAULT:tegra = "3072"
For my first test, I’m trying to apply my layout on a jetson-xavier-nx-devkit-emmc before trying with my machines.
I am encountering the following error:
