 dramforever | hi, has anyone been using the visionfive 2 sd card image in sd boot mode? can you confirm that it works from a fresh dd? https://github.com/NixOS/nixos-hardware/tree/master/starfive/visionfive/v2 | 10:10:47 |
| dramforever | so to check for sure, if you're in sd card mode and you remove the sd card it should immediately print an error like "boot fail" or something, no mention of u-boot spl | 10:11:27 |
| dramforever | well remove the sd card before booting | 10:11:40 |

hi, has anyone been using the visionfive 2 sd card image in sd boot mode? can you confirm that it works from a fresh dd? https://github.com/NixOS/nixos-hardware/tree/master/starfive/visionfive/v2 I have used it to boot custom M mode code instead of the SPL and it worked. | 10:12:42 |
| dramforever | thanks! | 10:13:19 |
| Alex | Do you need help debugging boot problems? | 10:13:39 |
| dramforever | i'm good, someone was asking in liberachat #riscv about the boot process, and was doubting if the gpt partition thing is real | 10:14:32 |
| dramforever | i don't have the hardware with me so i was just looking for a positive confirmation that it's a real thing | 10:15:00 |
| Alex | Ah, because the vendor revised all their documentation to recommend against using it, in some cases even removing references to it. | 10:15:10 |
| Alex | I might still have copies of some older versions of the documentation if it's no longer well documented. | 10:15:40 |

 outfoxxed | Continuing from last night in the main room here https://matrix.to/#/#users:nixos.org/$9PGx1smm5r8lM79J9wKW3uiI3zyGLogHe7d0t9DOjn0,
I'm attempting to get a milkv jupiter booting. So far I've made it here with an sdcard image:

with the commandline:

and I'm not sure where to go from here, because it doesn't seem to be starting init (or I'm just getting no logs, I see nothing about ttyS0 actually coming online) | 04:47:44 |
| outfoxxed | I've also copied the init binary in the nix store to /init in the rootfs, though I don't know if the kernel is trying to load from there or initrd | 04:48:24 |
| outfoxxed | made it to stage1 by manually loading everything, extlinux still won't | 09:17:41 |
