regarding Sculpt on virt_qemu_riscv

Mon Feb 13 17:32:47 CET 2023

Hello,
I am trying to build sculpt for virt_qemu_riscv.
As I could not find the "virt_qemu_riscv" directory inside genode. So I
cloned the riscv inside repos under genode from "
https://github.com/genodelabs/genode-riscv/".
Earlier while executing the command:
      > make run/log BOARD=virt_qemu_riscv KERNEL=hw
I got this error.:

genode build completed

using 'ld-hw.lib.so' as 'ld.lib.so'

core link address is 0xffffffc000000000

Aborting, received EOF

Log step failed, retry.

I had raised this issue then and I would like to answer your questions.

I could not fix qemu so I downloaded the RISC-V firmware
"opensbi-riscv64-virt-fw_jump.bin" and used it explicitly to run the elf
file generated. I got this output

and, Qemu popped up with a text "*Guest has not initialized the display yet*
".

Please tell me if this is all what I should expect from 'make run/log' or
if I have done something wrong ?

So, Now I am trying to build sculpt using:

> make run/sculpt BOARD=virt_qemu_riscv KERNEL=hw

I have added the virt_qemu platform in sculpt.run file. I have added a
driver configuration file under *'repos/gems/sculpt/drivers' and added
a  **default-virt_qemu_arm_riscv.sculpt
file under 'repos/gems/sculpt'.*

I am getting this error:

.

.

P.S. *- *The drivers_interactive package for this platform (riscv), is not
in *'repos/os/recipes/raw/' .... *rather its present in*
'genode/repos/riscv/recipes/raw'.*

All recipes related to riscv was not with genode, I had to add it into
*'genode/repos/'
*from github.

Please let me know What I can configure to execute this command sucessfully.
