  •  

• NixOS

  •  

• R9

  •  

• oreboot

  • Migrated to RustSBI 0.4.0 🤩

  • Ported DRAM init for Kendryte K230D

    • Kendryte K230D support by orangecms · Pull Request #764 · oreboot/oreboot  

    • Created main stage and successfully did an SBI test

    • Setup now lets you load everything via mask ROM USB protocol

      • Load DRAM init to SRAM and run, jump back to mask ROM

      • Load SBI test (S-mode code) to DRAM

      • Load main stage with SBI implementation as well

      • Continue running, see hello from SBI test 🎉

    • M-mode timer is not working, neither time CSR nor MMIO based mtime

    • https://mastodon.social/@CyReVolt/113930859208849486 

  • QEMU SBI test in oreboot

    • https://mastodon.social/deck/@CyReVolt/113953915242150820 

  • Bouffalo Lab BL808 PSRAM init done

    • https://mastodon.social/@CyReVolt/113852399724541310 

    • Dev live stream: oreboot on BL808 003: PSRAM init  

  Got bl_boot to the point where it can load any binary for any core to run immediately

• Firmware

  • Had two hack days at FOSDEM with Open Source Firmware Foundation

  • Extended kendryte_boot so you can load additional code to anywhere in RAM

• Flathub

  • Got freedesktop-sdk builds and buildstream support working

  • Added Pioneer to freedesktop’s infrastructure list

  • RISC-V build enablement · Issue #4378 · flathub/flathub  

  • Getting RISC-V support, having trouble with hardware access, only one Pioneer board right now
