Hello community,

I’m working on integrating Mender for A/B OTA updates into the Toradex tdx-reference-multimedia-image for the Apalis iMX8, built with Yocto and the Toradex BSP. My goal is to produce a .teziimg that includes the full Mender configuration—client, A/B partition layout, and U-Boot environment—ready for deployment via Toradex Easy Installer (Tezi) and capable of OTA updates . I’m using u-boot-toradex as the bootloader.Will u-boot-toradex (as patched by meta-mender-toradex-nxp) fully support Mender’s A/B requirements, especially boot counting and partition switching?

Hi @Rani13958,

Generally speaking, the Apalis iMX8 should be perfectly capable to support A/B updates and all required functionality.
To check this, you can use the bootloader integration check script (see Mender-validation: automatic integration checking) or follow the integration checklist at Integration checklist | Mender documentation
