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

Hi,

I am trying to boot Linux Kernel with statically linked initramfs on QEMU-
riscv64 target.
I followed the steps provided in the link

ata=zwyqm7ld1EANTy39vriuIMcP8uHDL8DIqZgJFRZdmoY%3D&reserved=0".
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
