Armbian does not support the s905x4

Thanks for the reply! I bought used and had no luck at all getting things running (this was some time ago and things are hazy). Have you written up your experience anywhere I could look at? Sent from my iPhone using Tapatalk

@0jay I'm sorry I never got a notification for your response here for some reason. I have two ESPRESSObin Ultra devices humming along just fine with no issues, everything working as far as I can tell, no patches to U-Boot or Linux needed. I'm not familiar with the Mochabin. Did you experience issues with it as well out-of-box?

Hi @y52, I've been using the bootloader builds from my repo above on my ESPRESSObin Ultra for quite some time now. Not only do they have up-to-date U-boot, but frequency scaling works perfectly. I'm not very familiar with the V5 and V7 variants, but I think the V7 has the same CPU (possibly different memory). > hostnamectl Static hostname: espressobin-ultra Icon name: computer-embedded Chassis: embedded Machine ID: 2ba0ba22c6164c Boot ID: 514bc8387b7847 Operating System: Arch Linux Kernel: Linux 6.17.3-1-a3700 Architecture: arm64 Hardware Vendor: globalscale Hardware Model: Globalscale Marvell ESPRESSOBin Ultra Board Firmware Version: 2025.10-ge50b1e871501 Firmware Date: Wed 2025-10-01 Firmware Age: 1month

Hi! Thanks for mentioning me. I've just noticed your message accidentally. It is indeed an interesting u-boot development. My both ESPRESSObin V5 and V7 are in production now. I can make some testing once I program their replacement. But no schedule has been fixed as yet pending acquiring a new board.
