I am building busybear-linux following the instructions on :

from 1-5 step by step.

1. git clone --recursive https://github.com/riscv/riscv-gnu-toolchain
2. git clone https://github.com/qemu/qemu
3. git clone https://github.com/torvalds/linux
4. git clone https://github.com/riscv/riscv-pk
5. git clone https://github.com/michaeljclark/busybear-linux

My platform is ubuntu 19.04

Did you figure out what the problem was?

[daqiren888]

Yes, finally found the problem was about the configurations:

At step 1, I used --with-abi=lp64 to build the riscv-gnu-toolchain.

At step 5, since I used lp64 at step 1, I should firstly modify the configuration file at
/busybear-linux/conf/busybear.config to let --with-abi=lp64 ( by default the value was --with-abi=lp64d )

problem solved, and everything is good.

[reimuser]

Ok. Thank you for your response!
I configured the riscv-gnu-toolchain with ./configure --prefix=/opt/riscv32 --with-arch=rv32ima --with-abi=ilp32 and changed the busybear.config file to --with-abi=lp32
Maybe there is the problem... I try to change the ./configure to --with-abi=lp32.
Did you change the busybear files as described in busybear-linux.diff?

I will write an update later.

[reimuser]

It works now. I changed --with-abi=lp32 to --with-abi=ilp32 in the busybear.conf file.

Now, I fail with sudo qemu-system-riscv32 -nographic -machine virt \ ...
Then I get: bbl loader
../machine/minit.c:79: assertion failed: !(read_csr(misa) & fd_mask)
Power off
Any idea? Apparently it is due to riscv-pk.

[daqiren888]

Here is what I did and it works:

Riscv-gnu-toolchain:
./configure --prefix=(my folder) --with-arch=rv64imafdc --with-abi=lp64

busybear.config file:
--with-abi=lp64

Start qemu with:

sudo qemu-system-riscv64 -nographic -machine virt -kernel riscv-pk/build/bbl -append "root=/dev/vda ro console=ttyS0" -drive file=busybear-linux/busybear.bin,format=raw,id=hd0 -device virtio-blk-device,drive=hd0
