Store/AMO access fault!

[nipunagarwala]

I am running a simple hello world program using the following command: $RISCV/bin/riscv64-unknown-elf-gcc -o hello hello.c <path_to_spike>/spike <path_to_pk>/bin/pk hello

On doing so, I get the following output:

:23.39-27.9: Warning (interrupt_provider): /cpus/cpu@0/interrupt-controller: Missing #address-cells in interrupt provider bbl loader =================WARNING: access out of range!================= Detect access on symbol root_page_table at addr 0x8001a070 with len = 0x12, expected len <= 0x8.

Background: Running this on Ubuntu 22 Installed Linux and Newlib installation, both. Spike seems to have been cleanly installed, and so does PK and riscv-gnu-toolchain. But I did not use the riscv-tools repo to install the packages.

Not sure if this is a problem with my software installation, or the spike/pk commands.
