[wjh-study]

When I refer to this doc https://github.com/riscv-admin/riscv-uefi-edk2-docs?tab=readme-ov-file,I want to start edk2 on the qemu-riscv-sifve-u540.
I can not enter UEFI SHELL to load my linux kernel.
This is my log....I do not know what happen on the qemu,Has anyone pay attention to this issue?
