misuzu I've been trying to boot your NixOS VF2 configuration (https://github.com/misuzu/nixos-vf2) on my rev1.3b board, but it doesn't seem to be working (continuous red LED, no green LED). I've also tried the pre-built native image you've published, but that didn't help.
I don't have any way of connecting serial to debug it, so I thought I'd ask you a few questions that'll help me figure out what's going wrong:
- I flashed the latest firmware using the manufacturer's pre-compiled Debian image, could that be the cause? (The Debian image still boots.)
- Should I expect ethernet or HDMI out to work with your image? (I'm hoping to get the Linux console on HDMI.)
- Do the on-board LEDs blink when the system successfully boots, similarly to the Debian image?
- The GPIO switches on the board are currently set to boot from SD, since that worked for the Debian image; should they be set to something else?
1 vendor firmware should work
2 ethernet should work, didn't test hdmi
3 red led should be on
4 there's no firmware in the image, boot switch should be set to boot from spi | 11:14:49 |
 j-k | has anyone recently tried m.2 ssd boot on VF2? | 11:19:55 |

has anyone recently tried m.2 ssd boot on VF2? root on nvme works | 11:21:57 |

FYI, my monitor is saying that there's no HDMI output. | 11:22:02 |

root on nvme works thanks. I'll need to take some time to set this up!
I think I saw you mention the cache has some native bits cached right? So if I'm using the matching nixpkgs in the flake & helpers etc I shouldn't be rebuilding absolutely everything right?

| misuzu | Vendor u-boot doesn't support booting from nvme out of box, you'll have too type stuff to the console via uart :D | 11:28:29 |

| misuzu | I've my efi partition on an sd card and root on an nvme | 11:30:44 |

I've my efi partition on an sd card and root on an nvme would this still be required after using the bootloader flashing step at the top of the repo? | 11:31:34 |

would this still be required after using the bootloader flashing step at the top of the repo? Yes, it will flash vendor u-boot | 11:31:59 |
| misuzu | There's flash-visionfive2-upstream, but it's not working properly | 11:33:00 |
| j-k | ah I see. for VF1 as far as I remember we were flashing a non-vendor u-boot because they had a weird setup and couldn't boot anything other than their silly ISOs | 11:33:06 |

There's flash-visionfive2-upstream, but it's not working properly hm why? | 11:33:24 |
| raitobezarius | I tried it and it worked | 11:33:26 |
| j-k | In reply to @misuzu:matrix.org
Yes, it will flash vendor u-boot ok right, yeah it does say recovery 🤦 | 11:33:29 |

hm why? *for nvme boot | 11:33:42 |
| Alex | Newer versions of the vendor's bootloader might support NVMe boot.

*for nvme boot ah yes yes correct | 11:34:13 |

 Lotte (it/its)/Cinny (she/her) θΔ& | I ended up moving the install to iscsi | 15:44:44 |
| Lotte (it/its)/Cinny (she/her) θΔ& | but it works now 🦀 | 15:44:50 |
| Lotte (it/its)/Cinny (she/her) θΔ& | semi related thing i just noticed, the vf2 apparently supports the Zbb extension | 15:45:35 |
| Lotte (it/its)/Cinny (she/her) θΔ& | and then i noticed that gcc was outputting suboptimal assembly for a test case but it’s fixed already | 15:46:08 |

semi related thing i just noticed, the vf2 apparently supports the Zbb extension Yes, it also has Zba despite neither being mentioned in the vendor's documentation. | 15:52:38 |
| Lotte (it/its)/Cinny (she/her) θΔ& | iirc the core ip they licensed does advertise support for the “B extension” | 15:53:18 |
| Lotte (it/its)/Cinny (she/her) θΔ& | and so does the IPL/firmware | 15:53:28 |
| Alex | For the SiFive U74, Zba and Zbb appear to be optional, so I'm not sure every CPU variant have them. | 15:54:39 |
| Lotte (it/its)/Cinny (she/her) θΔ& | yeah | 15:57:38 |
