@jock Thank you, I will try.

After more than six successful years with Helios4, I have to say goodbye to this platform and the highly valued, helpful, and knowledgeable Armbian forum. With 32-bit, it’s no longer feasible to continue using it in the future. I have installed the 4 8TB hard drives from the NAS into an Odroid H4+ (Intel, 64-bit), installed OMV8, and on top of that, Nextcloud-AIO Hub 26 Winter and AdGuardHome. Thank you very much for your support over the past few years. btw. The Helios4 hardware (excluding the hard drives) is still available.

Hmm that doesn't look great. It looks like it is crashing at random places vs the same place every time. It makes you wonder if you have a true hardware problem (e.g. bad memory). Can you never make it to a login prompt? I would double check all your memory locations for the FDT, ramfs and kernel to make sure you aren't accidentally overlapping anywhere. And yes, I would avoid starting anything at 0. I actually found a kernel bug from doing that. You could also consider trying to load the kernel as an EFISTUB directly. I don't know if that's supported by armbian or not, but you could experiment. You do know you can save u-boot variables to the SPINOR storage so you don't have to type them in every time, right?

@mrdeathjr Mainline Linux support for the A733 is still in its early stages. I currently have a Armbian build using a collection of patches sourced from the kernel mailing lists. However, I’m getting a lot of errors and haven't managed to boot to a login prompt. https://oftc.catirclogs.org/linux-sunxi/2026-03-23 13:07 <indy> hi all, is there any a733 upstreaming effort? 13:29 <apritzel> indy: effort is underway: pinctrl is WIP (patches have been on the list), and the clock patches have recently been posted 13:30 <apritzel> RTC and AXP are on the list as well, that would conclude the basic necessities to get a DT merged that wouldn't break in the future 15:25 <indy> apritzel_, is it targeted for 7.0? 15:29 <apritzel> indy: no, that's way too late, v7.0 is due to be released in like three weeks already. It's even too late now for v7.1. 15:30 <apritzel> and it's the usual bottleneck: reviews ... I hope I find some time soon to look at the clock patches With @alexc hard work porting the v1.4.8 BSP driver to kernel 6.18, I was able to create a working Armbian build for the Radxa A7Z. https://github.com/NickAlilovic/build/tree/Radxa-mainline-WIP

In my personal opinion with lastest changes showed in kernel lore on a733 https://lore.kernel.org/linux-sunxi/?q=a733 kernel 7.1 give many things for a733
