Hi Ilias, I have been testing with grub, and with the efi selftest. Here are the steps to test with a riscv grub:
1. Get grubriscv64.efi from e.g. the following .deb package wget http://launchpadlibrarian.net/754414418/grub-efi-riscv64-unsigned_2.12-5ubuntu5.1_riscv64.deb 2. Compile U-boot with qemu-riscv64_smode_defconfig. Enable CMD_WGET. 3. Create a tap interface: $ sudo ip tuntap add dev tap0 mode tap $ sudo ip addr add 10.0.0.0/24 dev tap0 $ sudo ip link set dev tap0 up 4. Start an http server in a directory containing grubriscv64.efi and a test file (e.g. a riscv kernel) $ sudo python3 -m http.server 80 --bind 10.0.0.0 5. Launch U-boot: $ qemu-system-riscv64 \ -machine virt \ -nographic \ -kernel u-boot \ -netdev tap,id=net0,ifname=tap0,script=no,downscript=no \ -device virtio-net-device,netdev=net0 6. Inside U-boot's console => setenv ipaddr 10.0.0.1 => setenv netmask 255.255.255.0 => wget 10.0.0.0:80/grubriscv64.efi <http://10.0.0.0/grubriscv64.efi> => bootefi $loadaddr 7. Print debug, check address and installed protocols (optional): grub> set debug="peimage,net" grub> net_ls_addr grub> lsefi 8. Download a test file, e.g. a kernel, through http (here Image is a riscv linux kernel): grub> linux (http,10.0.0.0:80)/Image 9. Try boot it: grub> boot Best, Adriano El jue, 14 nov 2024 a las 12:22, Ilias Apalodimas (< ilias.apalodi...@linaro.org>) escribió: > Hi Adriano, > > On Mon, 11 Nov 2024 at 23:10, Adriano Cordova <adria...@gmail.com> wrote: > >> Add support for EFI_HTTP_PROTOCOL, EFI_HTTP_SERVICE_BINDING_PROTOCOL, >> and EFI_IP4_CONFIG2_PROTOCOL. >> >> This series depends on the series 'wget: Expose wget to applications', >> also found at: >> https://github.com/0n41rd4/u-boot/commits/http-driver-wget >> >> The fist two patches of this series are not efi specific and have also >> been sent to the corresponding maintainers, but this series depends on >> them, so they are added here for redundancy.
