not in SPI mode (with the firmware flashed using nix run github:misuzu/nixos-vf2#flash-visionfive2-vendor /dev/ttyUSB0)

You probably have changed some settings is u-boot. To reset u-boot settings to default values you can use these commands:

env default -a
saveenv

I didn’t modify your uboot settings. I flashed the image and flashed the firmware using aforementioned method.    		18:37:47

It's not enough to flash u-boot to reset u-boot settings 		18:38:44
@thefossguy:matrix.orgPratham Patel Oh you mean the settings stored by the vendor’s firmware? 18:39:23
@thefossguy:matrix.orgPratham Patel It’s possible that i messed with the vendors firmware and that’s acting up right now lol 18:39:49
@thefossguy:matrix.orgPratham Patel I’ll take a look tomorrow morning    18:40:05

misuzu is nixos-cross-image-efi supposed to require RISC-V emulation to build?

alex@alex-pc3 ~/r/A/n/master (master)> nix build .#nixos-cross-image-efi --print-build-logs
error: a 'riscv64-linux' with features {} is required to build '/nix/store/03w7yyb2cqw3blz9biawkypig49lx2fc-bootstrap-tools.drv', but I am a

Nevermind, this is the consequence of my own changes.

Now to figure out why.

Nope, just regular x86_64-linux machine 		19:28:28

I noticed that the image (https://github.com/misuzu/nixos-vf2) didn't boot with all combinations of DIP switches so me being extra smart, I dd-ed uboot SPL and SBI firmware on /dev/sda1 and /dev/sda2 respectively and mvoed /boot to /dev/sda3 and / to /dev/sda4. Now, your derivation doesn't work because it expects "/dev/sda1" to be EFI?
https://github.com/misuzu/nixos-vf2/tree/master#u-boot-on-an-sd-card follow this if you want u-boot on an sdcard 		19:29:40

Oh neat, that means I can cancel building my dodgy attempt at tweaking your make-efi-image script. 		19:30:52

Try it on spare sdcard first, maybe I've written something wrong 🤡 		19:34:08
@misuzu:matrix.orgmisuzuThe image uses labels to mount partitions, so partition numbers shouldn't matter19:36:37

Doesn't that mean I could shrink my root partition a bit and put u-boot at the end of the disk? 		19:37:29

Root partition - no, efi partition - maybe 		19:38:15

Not enough funds, maybe NixOS foundation could chim in. Maybe raitobezarius has some better understanding of this platform.
I'd wait 		23:39:14
@raitobezarius:matrix.orgraitobezariusAs said in another channel23:39:24
@raitobezarius:matrix.orgraitobezariusThe speed of innovation in RISC V is sufficiently fast that by the time you get your MilkV, you may have to wait ~6-8 mo before you get the next generation which will probably much better at that moment23:40:07

Okay yeah, that worked. I thought reflashing the firmware would do the trick but now that I think of it, it only makes sense to keep the data separate :D 		04:04:03

If you mean the SPL or the flat binary, then no. 		04:05:45
