Error when trying to run linux in simulation

[hparpinel]

Hi, I am trying to run Linux in simulation. I followed the instructions in the linux.gen file but I get the following output.

Hi, What version of VexRiscv do you have ? i think that issue has been fixed. (error: too many arguments to function ‘IData VL_RANDOM_I()’)

[hparpinel]

Note: When I clone the repository using the command in the file linux.scala I get the older version git clone https://github.com/SpinalHDL/VexRiscv.git -b linux

I updated my version but now I am getting this error: ./obj_dir/VVexRiscv BOOT Liveness step failure FAIL linux at PC=80000000 REF PC=0 REF I=0 time=20016 make: *** [makefile:345: run] Error 255

[Dolu1990]

-b linux is very very outdated

git clone https://github.com/SpinalHDL/VexRiscv.git --recursive should be good

[hparpinel]

Thank you for your reply. I have cloned the repository using the command $ git clone https://github.com/SpinalHDL/VexRiscv.git --recursive However, when I try to to compile the machine mode emulator I get the following error: $ cd src/main/c/emulator $ make clean all rm -f build/emulator.elf rm -f build/emulator.hex rm -f build/emulator.map rm -f build/emulator.v rm -f build/emulator.bin rm -f build/emulator.asm find build -type f -name '*.o' -print0 | xargs -0 -r rm mkdir -p build/src/ riscv64-unknown-elf-gcc -c -march=rv32i -mabi=ilp32 -DUSE_GP -I../include -O3 -o build/src/main.o src/main.c src/main.c: In function 'trap': src/main.c:182:22: error: 'instruction' undeclared (first use in this function) uint32_t opcode = instruction & 0x7F; ^~~ src/main.c:182:22: note: each undeclared identifier is reported only once for each function it appears in make: *** [../common/standalone.mk:52: build/src/main.o] Error 1

This are the steps I am following to run Linux in simulation is there something I am missing?

== INSTALL SPINALHDL AND VEXRISCV $ git clone https://github.com/SpinalHDL/SpinalHDL.git -b dev $ git clone https://github.com/SpinalHDL/VexRiscv.git --recursive

== TOOLCHAIN AND EMULATOR $ version=riscv64-unknown-elf-gcc-8.3.0-2019.08.0-x86_64-linux-ubuntu14 wget -O riscv64-unknown-elf-gcc.tar.gz riscv https://static.dev.sifive.com/dev-tools/$version.tar.gz $ tar -xzvf riscv64-unknown-elf-gcc.tar.gz $ sudo mv $version /opt/riscv $ echo 'export PATH=/opt/riscv/bin:$PATH' >> ~/.bashrc

== BUILDROOT $ git clone https://github.com/SpinalHDL/buildroot.git -b vexriscv $ cd buildroot $ make spinal_vexriscv_sim_defconfig $ make -j$(nproc) $ output/host/bin/riscv32-linux-objcopy -O binary output/images/vmlinux output/images/Image

== COMPILE MACHINE MODE EMULATOR $ src/main/c/emulator $ make clean all

== RUN LINUX IN SIMULATION $ "runMain vexriscv.demo.LinuxGen" $ cd src/test/cpp/regression $ export BUILDROOT=/path/to/buildroot $ make clean run IBUS=CACHED DBUS=CACHED DEBUG_PLUGIN=STD SUPERVISOR=yes CSR=yes DEBUG_PLUGIN=no COMPRESSED=no LRSC=yes AMO=yes REDO=0 DHRYSTONE=no LINUX_SOC=yes EMULATOR=../../../main/c/emulator/build/emulator.bin VMLINUX=$BUILDROOT/output/images/Image DTB=$BUILDROOT/board/spinal/vexriscv_sim/rv32.dtb RAMDISK=$BUILDROOT/output/images/rootfs.cpio WITH_USER_IO=yes TRACE=no FLOW_INFO=no

[Dolu1990]

Hmmm, try just : make clean make

Worked for me.

[hparpinel]

That worked but I am still getting the error below when I run $ make clean run IBUS=CACHED DBUS=CACHED DEBUG_PLUGIN=STD SUPERVISOR=yes CSR=yes DEBUG_PLUGIN=no COMPRESSED=no LRSC=yes AMO=yes REDO=0 DHRYSTONE=no LINUX_SOC=yes EMULATOR=../../../main/c/emulator/build/emulator.bin VMLINUX=$BUILDROOT/output/images/Image DTB=$BUILDROOT/board/spinal/vexriscv_sim/rv32.dtb RAMDISK=$BUILDROOT/output/images/rootfs.cpio WITH_USER_IO=yes TRACE=no FLOW_INFO=no

ERROR: ./obj_dir/VVexRiscv BOOT Liveness step failure FAIL linux at PC=80000000 REF PC=0 REF I=0 time=20016 make: *** [makefile:345: run] Error 255

[Dolu1990]

Ahhh, so, one issue you got is that DEBUG_PLUGIN=no should be DEBUG_PLUGIN=STD in your command line, because the debug plugin was added since.

Here is how i just got it to run :

export ARCH_LINUX=rv32ima
export VMLINUX=../../resources/VexRiscvRegressionData/sim/linux/${ARCH_LINUX}/Image
export DTB=../../resources/VexRiscvRegressionData/sim/linux/${ARCH_LINUX}/rv32.dtb
export RAMDISK=../../resources/VexRiscvRegressionData/sim/linux/${ARCH_LINUX}/rootfs.cpio
export EMULATOR=../../resources/VexRiscvRegressionData/sim/linux/emulator/emulator.bin

make clean run IBUS=CACHED DBUS=CACHED  DEBUG_PLUGIN=STD SUPERVISOR=yes CSR=yes DEBUG_PLUGIN=STD  COMPRESSED=no LRSC=yes AMO=yes REDO=0 DHRYSTONE=no LINUX_SOC=yes WITH_USER_IO=yes TRACE=no FLOW_INFO=no
