Since I want to reword what I’m asking about this topic, I’m going to start a new topic, after which I’ll kill the old, similar one (if I have permission).
I have a NXP i.MX93 FRDM board and would dearly love to boot eLxr 26.04.1 on it straight from the micro SD card, but when I ask Google about this, I get two very different answers.
The first answer is that I can grab the current compressed eLxr Edge image for NXP targets straight from the downloads page (say,the minimal one, elxr-minimal-imx-26.04.01-arm64.img), uncompress it and “dd” the image to the SD card, then do the regular plug it into the board, connect serial port and so on, just as I’ve done so many times with other boards. I could have sworn I tried this a few days ago and got nowhere (just hung), but this description clearly suggests that I can use the downloaded image directly. (I’m going to try again this afternoon.)
The second approach which Google seems to find more frequently is that I need to take a “hybrid” approach, by grabbing a bootable .wic image from NXP, opening it up and replacing the root filesystem with “elxr-rootfs-26.04.1-arm64.tar.gz”, which tarball I do not see on the eLxr downloads page so I don’t know how I would do that anyway.
Can this be done? Is it written down somewhere? And should it even work for the FRDM board, as I vaguely recall reading somewhere that it’s only the i.MX93 EVK board that is supported, not the FRDM, but I can’t remember where I read that. Like I said, I’ll try again this afternoon with the direct image approach, but I am open to good advice. It would be nice to get this working since the downloads page certainly leaves the impression that 26.04.01 should work on i.MX93 hardware.
