18:41 <ssm_> hey all, I'm new to u-boot and have a nanopi r1 I want to install openbsd on. I was able to find a prebuilt dtb that's compatible with the device, but I can't find a u-boot.bin. I was able to successfully get the board to boot with the nanopi neo u-boot-sunxi-with-spl.bin with the docs here: https://ftp.openbsd.org/pub/OpenBSD/7.6/armv7/INSTALL.armv7 using command `dd

18:41 <ssm_> if=/usr/local/share/u-boot/board/u-boot-sunxi-with-spl.bin of=/dev/sdXc bs=1024 seek=8` to write the u-boot, and then using env in u-boot to edit fdtfile to the correct dtb file. I have two questions, how do I know the correct offset (8192 bytes in this case) to write u-boot (seems different per board?), and when writing to the same offset when installing to the emmc, u-boot was unable to find any mmc

18:41 <ssm_> devices and I couldn't even reach the u-boot cli (I wrote the u-boot after installing openbsd)

18:43 <ssm_> I also tried copying u-boot with dd off a vendor image but it seems to panic after I run bootefi

19:05 <marex> ssm_: did you try some older version of mainline u-boot around the time the board support got added ?

19:19 <ssm_> marex: didn't think of that, I'll look

22:22 <ssm_> marex: I couldn't find anything skimming through images from around 2019 to 2022 unfortunately

22:23 <ssm_> also I found the 8k offset in the README.sunxi file

22:24 <marex> ssm_: basically ... git worktree add -d /tmp/teststuff v2021.04 ; cd /tmp/teststuff ; ...build...test...
