OPI 4A - Allwinner T527

[AurealNix]

@L. Jorge Soares  Thanks a lot for testing both — genuinely, this is the most useful thing anyone can do for the project. 🙏

CLI: great to hear it boots and HDMI works on your setup — that's the first confirmation from hardware other than mine, so it means a lot. If you get time, I'd love to hear how it holds up (networking, USB, and the 4 GB variant if that's what you have).

Root password: that's by design, not a bug. Root login is locked on purpose — the image ships with a default user / user account and SSH enabled, so an open root account would be a security hole. Use the user account with sudo:

• root shell: sudo -i (or sudo su)
• to set a root password if you really want one: sudo passwd root

KDE image + Etcher error: let's pin it down. Full disclosure — I flash with dd myself, so I haven't actually run these images through BalenaEtcher; I'll test the Etcher path on my end to try to reproduce it. In the meantime, two quick checks:

• Verify the download — a truncated/corrupt download is the #1 cause of Etcher errors. The desktop image sha256 is: 63b0019423d2a320aaa5fe58df97db68823b353a30510ffa863fec475904e0ba Check yours: sha256sum on Linux/Mac, or certutil -hashfile <file> SHA256 on Windows. If it doesn't match, re-download. And thanks for the heads up — I'll also double-check on my end that the file on the release didn't get corrupted during upload.
• Card size — the desktop image is ~5.3 GB when written (bigger than the CLI one), so it needs an 8 GB or larger card. A smaller/oddly-sized card makes Etcher fail.

If the checksum matches and the card is 8 GB+ but it still errors, it's most likely Etcher choking on the .xz — try Raspberry Pi Imager (Use custom → pick the .img.xz), Rufus (it writes in DD Image mode and takes the .xz directly), or on Linux just dd: xz -dc aurealnix-opi4a-debian13-v0.2.img.xz | sudo dd of=/dev/sdX bs=4M status=progress

And if you can, paste the exact Etcher error text — that tells me straight away whether it's a size, decompression, or validation issue. Thanks again for digging in! 🙌
