rec { description = '' Belkin RT-3200 / Linksys E8450 ****************************** This device is based on a 64 bit Mediatek MT7622 ARM platform, and is "work in progress" in Liminix. The factory flash image contains ECC errors that make it incompatible with Liminix: you need to use the `OpenWrt UBI Installer `_ to rewrite the partition layout before you can flash Liminix onto it (or even use it with "tftpboot", if you want the wireless to work). - MediaTek MT7622BV (1350MHz) - 128MB NAND flash - 512MB RAM - b/g/n wireless using MediaTek MT7622BV (MT7615E driver) - a/n/ac/ax wireless using MediaTek MT7915E ''; installer = "ubimage"; system = { crossSystem = { config = "aarch64-unknown-linux-musl"; }; }; module = {pkgs, config, lib, ... }: let firmware = pkgs.stdenv.mkDerivation { name = "wlan-firmware"; phases = ["installPhase"]; installPhase = '' mkdir $out cp ${pkgs.linux-firmware}/lib/firmware/mediatek/{mt7915,mt7615,mt7622}* $out ''; }; in { imports = [ ../../modules/arch/aarch64.nix ]; kernel = { src = pkgs.pkgsBuildBuild.fetchurl { name = "linux.tar.gz"; url = "https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.15.71.tar.gz"; hash = "sha256-yhO2cXIeIgUxkSZf/4aAsF11uxyh+UUZu6D1h92vCD8="; }; extraPatchPhase = '' ${pkgs.openwrt.applyPatches.mediatek} ''; config = { PCI = "y"; ARCH_MEDIATEK = "y"; # ARM_MEDIATEK_CPUFREQ = "y"; # needed for "Cannot find regmap for /infracfg@10000000" MFD_SYSCON = "y"; MTK_INFRACFG = "y"; MTK_PMIC_WRAP = "y"; MTK_EFUSE="y"; # MTK_HSDMA="y"; MTK_SCPSYS="y"; MTK_SCPSYS_PM_DOMAINS="y"; # MTK_THERMAL="y"; MTK_TIMER="y"; COMMON_CLK_MT7622 = "y"; COMMON_CLK_MT7622_ETHSYS = "y"; COMMON_CLK_MT7622_HIFSYS = "y"; COMMON_CLK_MT7622_AUDSYS = "y"; PM_CLK="y"; REGMAP_MMIO = "y"; CLKSRC_MMIO = "y"; REGMAP = "y"; MEDIATEK_GE_PHY = "y"; # MEDIATEK_MT6577_AUXADC = "y"; # MEDIATEK_WATCHDOG = "y"; NET_MEDIATEK_SOC = "y"; NET_MEDIATEK_SOC_WED = "y"; NET_MEDIATEK_STAR_EMAC = "y"; # this enables REGMAP_MMIO NET_VENDOR_MEDIATEK = "y"; PCIE_MEDIATEK = "y"; BLOCK = "y"; # move this to base option SPI_MASTER = "y"; SPI = "y"; SPI_MEM="y"; SPI_MTK_NOR="y"; SPI_MTK_SNFI = "y"; MTD = "y"; MTD_BLOCK = "y"; MTD_RAW_NAND = "y"; MTD_NAND_MTK = "y"; MTD_NAND_MTK_BMT = "y"; # Bad-block Management Table MTD_NAND_ECC_MEDIATEK= "y"; MTD_NAND_ECC_SW_HAMMING= "y"; MTD_SPI_NAND= "y"; MTD_OF_PARTS = "y"; MTD_NAND_CORE= "y"; MTD_SPI_NOR= "y"; MTD_SPLIT_FIRMWARE= "y"; MTD_SPLIT_FIT_FW= "y"; MMC = "y"; MMC_BLOCK = "y"; MMC_CQHCI = "y"; MMC_MTK = "y"; # Distributed Switch Architecture is needed # to make the ethernet ports visible NET_DSA="y"; NET_DSA_MT7530="y"; NET_DSA_TAG_MTK="y"; PSTORE = "y"; PSTORE_RAM = "y"; PSTORE_CONSOLE = "y"; PSTORE_DEFLATE_COMPRESS = "n"; SERIAL_8250 = "y"; SERIAL_8250_CONSOLE = "y"; SERIAL_8250_MT6577="y"; # SERIAL_8250_NR_UARTS="3"; # SERIAL_8250_RUNTIME_UARTS="3"; SERIAL_OF_PLATFORM="y"; }; }; boot = { commandLine = [ "console=ttyS0,115200" ]; tftp.loadAddress = "0x4007ff28"; imageFormat = "fit"; }; filesystem = let inherit (pkgs.pseudofile) dir symlink; in dir { lib = dir { firmware = dir { mediatek = symlink firmware; }; }; }; hardware = let openwrt = pkgs.openwrt; mac80211 = pkgs.mac80211.override { drivers = [ "mt7615e" "mt7915e" ]; klibBuild = config.system.outputs.kernel.modulesupport; }; in { ubi = { minIOSize = "2048"; eraseBlockSize = "126976"; maxLEBcount = "1024"; # guessing }; defaultOutput = installer; # the kernel expects this to be on a 2MB boundary.
