 Alex | I tried updating my VF2 to latest nixos-unstable (as of ~1 week ago) and now it won't boot...

It seems like there's something wrong with the bootloader on the EFI partition.
Switching back to the bootloader of the previous version worked.

Has anyone else booted such a recent Nixpkgs version? | 22:10:19 |
| Alex | (I did try reformatting the boot partition several times and checking for Nix store corruption. Neither of those resolved the issue.) | 22:32:49 |

 Mic92 | Steven Keuchel: Do you have some configuration for booting with EFI? I think I flashed edk2 correctly but it's hard to verify without any graphical output. I have the NixOS image you provided on the sd card and the original fedora on the NVME. In theory the Fedora should also boot with EFI because it has a efi grub binary. Removing the SD-card however will result in nothing to happen. | 13:24:11 |
| Mic92 | The early boot with the SD card looks like this:
SOPHGO ZSBL
sg2042:v0.3
sg2042 work in single socket mode
chip0 ddr info: raw data=0x5050505,
ddr0 size:0x800000000

ddr3 size:0x800000000
SD initializing 100000000Hz (transfer frequency at 25000000Hz)
sd card init ok

rv boot from sd card
SD initializing 100000000Hz (transfer frequency at 25000000Hz)

0:riscv64/riscv64_Image file size is 26265600

 Steven Keuchel | You don't get any output from the zbsl without the SD card? This indicates that something is wrong with the firmware in the SPI. To figure out what is going wrong exactly you would need to get the output of the tf-a, i.e. the boot stages before the zsbl. | 13:54:38 |
| Steven Keuchel | You can also EFI boot using LinuxBoot, that's at least how their early fedora images did it. | 13:55:45 |
| Steven Keuchel | Did you flash edk2 to SPI or to SD? | 13:56:40 |
| Mic92 | Steven Keuchel: ok. So I would flash their LinuxBoot to SPI and than use grub with efi support? | 13:56:45 |
| Mic92 | I flashed to SPI with flashcp | 13:56:52 |

Steven Keuchel: ok. So I would flash their LinuxBoot to SPI and than use grub with efi support? Yep. I have only used systemd-boot, but shouldn't make a big difference. | 13:58:40 |
| Mic92 | Ok. With linuxboot it worked... | 16:00:28 |

Has anyone else booted such a recent Nixpkgs version? I switched to generic-extlinux-compatible and now it boots.
Bonus: rebooting seems to work better too now (previously it would often freeze before syncing/unmounting file systems and require a hard reset). | 20:51:50 |
