Hi arm@, Later last year I bought a Banana Pi board and, at that time, was able to boot OpenBSD on it. I can't really remember where it stopped, since it's not supported, but at least it booted.
I tried to do the same thing this week, however without success. Here is the steps I took (to simplify, full log at the end): sunxi# setenv autoload off sunxi# dhcp sunxi# setenv bootargs sd0a:/bsd sunxi# setenv serverip 192.168.1.1 sunxi# tftpboot openbsd/bsd.umg sunxi# bootm I checked two references, one from tech@ [1] and one from LeMaker forum [2], but noone helped. The later is for 5.5, but things have changed since then.

I have a setup in which I export an /usr/src from an OpenBSD/amd64 machine to it and then I'm able to compile a new kernel to the Banana Pi if it's the case. I tried also to load Bananapi.bin (generated from the fex file description) also, which I downloaded from a NetBSD mirror, and then loaded with some extra commands at U-Boot before trying to boot OpenBSD itself: sunxi# setenv bootargs sysconfig=0x43000000 sunxi# tftpboot 0x43000000 192.168.1.1:Bananapi.bin I can't figure it out how this is related to OpenBSD not booting, nor if OpenBSD can see this sysconfig= variable. I tried with older versions of U-Boot (not -mainline), but these were buggy when fetching the .umg from tftp (timeout). The board is OK since I can boot NetBSD on it. I would appreciate any hints on this. Meanwhile, if someone has any diffs lying around and would like to share for testing, I would be glad to compile a new kernel and test. Thank you. --- full log --- U-Boot 2015.04-rc4-gb81bdf6 (Mar 25 2015 - 14:16:04) Allwinner Technology CPU: Allwinner A20 (SUN7I) I2C: ready DRAM: 1 GiB MMC: SUNXI SD/MMC: 0 *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial SCSI: SUNXI SCSI INIT SATA link 0 timeout.
