I have an NXP FRDM i.MX 93 board and the docs appear to suggest that I can boot eLxr 26.04.1 from the micro SD card, but Google tells me:
“To run eLxr Linux 26.04.1 (an enterprise-grade Debian-based derivative optimized for intelligent edge devices) on the NXP i.MX93 FRDM development board, you must adopt a hybrid approach. Because eLxr provides a clean Debian-like user space, you need to combine the eLxr root filesystem (rootfs) with NXP’s hardware-specific boot assets (U-Boot, ARM Trusted Firmware, and the Linux kernel).”
… then goes on to instruct that I need to first get the standard NXP-supplied .wic image for the board, open it up, and replace the rootfs part with the “elxr-rootfs-26.04.1-arm64.tar.gz” tarball from “the official eLxr release registry” (which I don’t immediately see).
Is there a verified process for doing this? Is the above correct? And if it is, where does one find that tarball? Or is there a simpler, official way to do this?
ADDENDUM: Asking the question of Google with a slightly different wording now suggests that I can boot directly from the eLxr image, so I’m about to try that with elxr-minimal-imx-26.04.01-arm64.img.
Note that I don’t want to flash to eMMC yet, I just want to boot from microSD card.
