# dev/build TLDRs
* `nix flake show .`
* `nix repl` followed by `:lf .` to much about in a REPL
* `nix build .#nixosConfigurations.asgaut.config.system.build.sdImage`
* `nix build .#images.asgaut-sd` to cross build
* `TODO` to build via binfmt emulation
* `zstd -vdcfT4 result/sd-image/*.img.zst | dd of=/dev/sda2 status=progress; sync`
## VF2 Overview
* The VisionFive 2
* Shortname: `vf2`
* https://www.kickstarter.com/projects/starfive/visionfive-2
* https://wiki.rvspace.org/
* StarFive JH7110 64-bit CPU
* CPU: quad SiFive U74 1.5GHz cores and comes paired with
* GPU: BXE-4-32 GPU from Imagination Technologies.
* OpenGL ES 3.2
* OpenCL 1.2
* Vulkan 1.2
* 2/4/8 GB RAM
* IO
* 1x HMDI (up to 4kp30)
* H.264 decode
* H.265 decode/encode
* 2x Gigabit Ethernet
* 2x USB 2.0
* 2x USB 3.0
* 2x M.2 NVMe
* MIPI CSI
* MIPI DSI
* MIPI LCD
* 4pin GPIO
* power:
* 5v DC via USB-C PD up to 30W
* 5v Dc via GPIO minimum 3A
* PoE (requires separate hardware module?)
* Storage
* SD
* NVMe
* SPI flash
* Their linux tree
* U-Boot
* used as firmware and bootloader (instead of GRUB like for x86) on ARM and RISCV
* [Generic Distro Configuration Concept](https://github.com/u-boot/u-boot/blob/master/doc/develop/distro.rst)
* U-Boot is scripted to scan all attached storage devices & partitions and look for a file named /extlinux/extlinux.conf or /boot/extlinux/extlinux.conf
