This should probably go to meta-oe? Oe-core carries essential packages and toolchains and this doesn't seem like it meets the criteria.

Hello Dario I have some questions. Why are you maintaining a custom version for this ? I can see that U-boot has already a support for this: https://github.com/u-boot/u-boot/tree/master/tools/fwumdata_src Also, vendors U-boot provide support for this, such as ST/iMX: https://github.com/STMicroelectronics/u-boot/blob/v2023.10-stm32mp/tools/mkfwumdata.c I see that the already provided tool is enough to update metadata (supports V2), so what your library is adding to that ? Do we really need it in OE core or meta-oe ?

In addition to Alex comment, I note build is failing on the autobuilder: ERROR: libfwumdata-0.1.0-r0 do_unpack: Recipes that set S = "${WORKDIR}/git" or S = "${UNPACKDIR}/git" should remove that assignment, as S set by bitbake.conf in oe-core now works. https://autobuilder.yoctoproject.org/valkyrie/#/builders/59/builds/3709 Thanks, Mathieu
Hi Alexander, On Wed, Apr 29, 2026 at 5:12 PM Alexander Kanavin <alex.kanavin@gmail.com> wrote: > This should probably go to meta-oe? Oe-core carries essential packages > and toolchains and this doesn't seem like it meets the criteria. > Hi Alex, I submitted this to oe-core because it seems to me similar to libubootenv. On platforms using the FWU A/B scheme (like STM32MP25), FWU metadata effectively replaces traditional U-Boot variables as the only mechanism to control boot flow. Furthermore I recently submitted a patch [1] to SWUpdate that uses this library. The SWUpdate maintainer pointed out that managing these FWU metadata fields belongs logically to SWUpdate's "bootloader" interface, rather than being handled as a generic script. This reinforces that libfwumdata operates in the exact same domain as U-Boot environment variables. Finally, since it shares libubootenv's configuration pattern management, oe-core seemed the natural fit. However, I am perfectly fine moving it to meta-oe if you prefer.

The distinction between the two tools in a real-world scenario, can be seen in my recent PR for the ST BSP [1]; Build-time: In commit [2] mkfwumdata is used to generate the initial metadata file to be included in the WIC image. git grep TF_A_METADATA_TOOL recipes-bsp/trusted-firmware-a/tf-a-stm32mp.inc:TF_A_METADATA_TOOL_NAME ?= "mkfwumdata" recipes-bsp/trusted-firmware-a/tf-a-stm32mp.inc:TF_A_METADATA_TOOL ?= "${STAGING_BINDIR_NATIVE}/${TF_A_METADATA_TOOL_NAME}" Runtime: In commit [3], fwumdata is used within a systemd service. Upon boot, it checks if the current bank is in the "valid" state and sets it to "accepted" to prevent the Arm Trusted Firmware (ATF) from performing an unwanted rollback. The next logical step, and the reason for this patch, is to allow OTA managers like SWUpdate or RAUC, as well as proprietary applications, to easily trigger a bank switch. While they could theoretically call the fwumdata command-line tool, providing a dedicated, lightweight C library is a much cleaner and more integrated approach for C/C++ applications than relying on system() or exec(). Furthermore, this first version of libfwumdata (v0.1.0) minimizes write operations to just the three fields strictly necessary for boot bank selection: - active_index - previous_index - bank_state This limited scope currently provides the added benefit of increasing safety by preventing userspace applications from accidentally corrupting other parts of the metadata.
