Linux boot #314

Open tromedo opened 5 years ago

tromedo commented 5 years ago

Hi,

I used Spike to boot linux using the riscv tools but the linux boot sequence seems to stop at Bootconsole[early0] disabled.

I tried adding kernel command line root=/dev/vda ro console=ttyS0 but didn't work. The same console settings worls in QEMU. Also checked the .config file for the line CONFIG_HVC_RISCV_SBI=y. It was there. Still coulnd't get past it.

Tried with Linux kernel version 4.19 to 5.2. No luck. Am I doing something wrong here?

Steps I followed:

Compiled linux with Riscv toolchain compiled riscv-pk with ../configure --host=riscv64-unknown-elf --with-payload= [path to vmlinux] used "Spike bbl" to start spike image.

Please let me know if any more info is required.

Sorry, noob here.

Attaching terminal output
