I'm building a simple "hello, world" project and running into some bugs.
The code works, but the after execution there is an exception. It appears to be in restore_user_context or nearby. Can anyone point out what the problem could be here? user@user-KVM:/mnt/data/sel4hello_manifest/build$ qemu-system-riscv64 --machine spike --nographic --serial mon:stdio --m size=4095M --bios images/hello-image-riscv-spike bbl loader ELF-loader started on (HART 0) (NODES 1) paddr=[80200000..80312d0f] Looking for DTB in CPIO archive...found at 802e5910.
