Linux booting issue with edk2 uefi on riscv64 qemu
|
Palanivel Duraisamy
Hi,
I am trying to boot Linux Kernel with statically linked initramfs on QEMU-riscv64 target. I followed the steps provided in the link "https://github.com/riscv-admin/riscv-uefi-edk2-docs". Built firmware for u540 board using the command "build -a RISCV64 -p Platform/SiFive/U5SeriesPkg/FreedomU540HiFiveUnleashedBoard/U540.dsc -t GCC5". Ran the command "qemu-system-riscv64 -cpu sifive-u54 -machine sifive_u -bios U540.fd" to boot Linux. I am getting uefi shell prompt. The uefi map commands gives "map: No mapping found." error. I would like to know the procedure to bring up Linux with UEFI firmware. Regards Palanivel |

Hi Palanivel, U540 should be able to boot to kernel if follow the steps mentioned in https://github.com/riscv-admin/riscv-uefi-edk2-docs, everything was fine back to that moment. However, both me and Daniel were no longer with RISC-V. I add Sunil to the loop see if he can help on this. Atish atishp@... was the collaborator for booting U540 edk2 binary to kernel on qemu. I am not sure if he could give some advices on this or not. Thanks Abner -----Original Message----- |

Hi Sunil,
I followed the given instructions in the document. I am getting UEFI shell prompt. The document says the following commands(step 6) need to be run on uefi shell. FS0 has the linux-riscv64.elf file. embeddedramdisk 4f2f3d7b-35ef-411b-9d26-e76ecacbaf8b map -r fs0: The "embbedramdisk" command in my setup fails. I think this command is missing and some modifications in EDK2 are needed to add this command. I am ok with "virt" machine type.

But let me know if you see any issues. I will try to help. Having said that, there is a series I am working on to support qemu virt machine which is not yet merged. If you are fine with "virt" machine instead of U540, let me know. It has latest design and supports disks similar to other architectures.

Thanks, Sunil.
Linux boots with this firmware on 'virt' machine.
