Boot Linux on Spike #294

Hi,

I am trying to boot newest linux kernel with Spike, however it seems to stall after console disabled. I am not sure if any one has the same issue on that:

The setup steps I followed is what I did in 2017

tool-chain busybox build rootfs.cpio compile linux compile bbl

Hi, I have the same problem trying to load the latest LTS kernel (4.19.37). Even though an initramfs is linked into the kernel, the bootloader bbl is not able to find and load it. The same kernel works fine, when booting using qemu. I already tried different toolchains: riscv64-unknown-elf (7.2.0), riscv64-unknown-linux-gnu (7.2.0), riscv64-linux-gnu (8.3.0). Any ideas would be helpful, thanks.

@Jimmyzshs Try the versions tagged in the v1_0 branch of freedom-u-sdk (https://github.com/sifive/freedom-u-sdk/tree/v1_0). Using the kernel and toolchain from this repo I got it working.
