Thanks to @brynet on bsd.network, who pointed out that we do have the necessary riscv-elf gcc toolchain in ports: https://bsd.network/@brynet/115540664782541348 I was able to build the new u-boot on OpenBSD. # pkg_add git riscv-elf-gcc opensbi riscv-elf-gcc gcc gmake swig bison py3-setuptools $ git clone -b d1-wip https://github.com/smaeul/u-boot u-boot-d1 $ cd u-boot-d1 $ gmake CC=egcc nezha_defconfig $ gmake -j8 CROSS_COMPILE=riscv64-unknown-elf- OPENSBI=/usr/local/share/opensbi/generic/fw_dynamic.bin # dd if=./u-boot-sunxi-with-spl.bin of=/dev/??? bs=1k seek=128 conv=sync The above needs to `dd` to an sdcard I believe and you need to install OpenBSD onto a USB stick. I did try copying sun20i-d1-nezha.dtb from sysutils/dtb to the fat partition on the sdcard, but it caused memory errors, I assume because that dtb is for the 2G version and I have the 1G. Not 100% on that though. > The dmesg (that I haven't looked closely at) is: > > https://dmesgd.nycbug.org/index.cgi?do=view&id=8692 > > OpenBSD 7.8-current (GENERIC) #59: Wed Nov 12 10:39:03 MST 2025 > [email protected]:/usr/src/sys/arch/riscv64/compile/GENERIC > real mem = 1073741824 (1024MB) > avail mem = 1008242688 (961MB) > SBI: OpenSBI v1.7, SBI Specification Version 3.0 > random: good seed from bootblocks > mainbus0 at root: Allwinner D1 Nezha > cpu0 at mainbus0: T-Head arch 0 imp 0 rv64imafdc > intc0 at cpu0 > cpu0: 32KB 64b/line 128-way L1 I-cache, 32KB 64b/line 256-way L1 D-cache > "fit-images" at mainbus0 not configured > "dcxo-clk" at mainbus0 not configured > simplebus0 at mainbus0: "soc" > sxipio0 at simplebus0: 88 pins > sxiccmu0 at simplebus0 > plic0 at simplebus0 > sxitimer0 at simplebus0: 24000 kHz > sxidog0 at simplebus0 > com0 at simplebus0: dw16550 > com0: console > com1 at simplebus0: dw16550 > "i2c" at simplebus0 not configured > "syscon" at simplebus0 not configured > "dma-controller" at simplebus0 not configured > "efuse" at simplebus0 not configured > "crypto" at simplebus0 not configured > "dram-controller" at simplebus0 not configured > sximmc0 at simplebus0 > sdmmc0 at sximmc0: 4-bit, sd high-speed, mmc high-speed, dma > sximmc1 at simplebus0 > sdmmc1 at sximmc1: 4-bit, sd high-speed, mmc high-speed, dma > "usb" at simplebus0 not configured > "phy" at simplebus0 not configured > ehci0 at simplebus0 > usb0 at ehci0: USB revision 2.0 > uhub0 at usb0 configuration 1 interface 0 "Generic EHCI root hub" rev > 2.00/1.00 addr 1 > ohci0 at simplebus0: version 1.0 > ehci1 at simplebus0 > usb1 at ehci1: USB revision 2.0 > uhub1 at usb1 configuration 1 interface 0 "Generic EHCI root hub" rev > 2.00/1.00 addr 1 > ohci1 at simplebus0: version 1.0 > dwxe0 at simplebus0: address f6:64:d9:b9:b2:55 > rgephy0 at dwxe0 phy 1: RTL8169S/8110S/8211, rev. 6 > "clock-controller" at simplebus0 not configured > "mixer" at simplebus0 not configured > "mixer" at simplebus0 not configured > "phy" at simplebus0 not configured > "tcon-top" at simplebus0 not configured > "lcd-controller" at simplebus0 not configured > "lcd-controller" at simplebus0 not configured > "power-controller" at simplebus0 not configured > "clock-controller" at simplebus0 not configured > sxirtc0 at simplebus0 > sxidog1 at simplebus0 > sxidog2 at simplebus0 > gpio0 at sxipio0: 32 pins > gpio1 at sxipio0: 32 pins > gpio2 at sxipio0: 32 pins > gpio3 at sxipio0: 32 pins > gpio4 at sxipio0: 32 pins > gpio5 at sxipio0: 32 pins > gpio6 at sxipio0: 32 pins > usb2 at ohci0: USB revision 1.0 > uhub2 at usb2 configuration 1 interface 0 "Generic OHCI root hub" rev > 1.00/1.00 addr 1 > usb3 at ohci1: USB revision 1.0 > uhub3 at usb3 configuration 1 interface 0 "Generic OHCI root hub" rev > 1.00/1.00 addr 1 > "opp-table-cpu" at mainbus0 not configured > "pmu" at mainbus0 not configured > "vcc" at mainbus0 not configured > "vcc-3v3" at mainbus0 not configured > "usbvbus" at mainbus0 not configured > "vdd-cpu" at mainbus0 not configured > "wifi-pwrseq" at mainbus0 not configured > "binman" at mainbus0 not configured > sdmmc1: can't enable card > umass0 at uhub1 port 1 configuration 1 interface 0 "USB SanDisk 3.2Gen1" rev > 2.10/1.00 addr 2 > umass0: using SCSI over Bulk-Only > scsibus0 at umass0: 2 targets, initiator 0 > sd0 at scsibus0 targ 1 lun 0: <USB, SanDisk 3.2Gen1, 1.00> removable > serial.07815583810786ac2d21 > sd0: 29358MB, 512 bytes/sector, 60125184 sectors > vscsi0 at root > scsibus1 at vscsi0: 256 targets > softraid0 at root > scsibus2 at softraid0: 256 targets > root on sd0a (0f83db59e45e7b31.a) swap on sd0b dump on sd0b > sxiccmu_d1_set_frequency: 0x00000084 > cpu0: clock not implemented > -- andrew The programmer's national anthem is 'AAAAAAAARRRRGHHHHH!!'.
