Error with emulator-rocketchip-BOOMConfig (cannot generate right *.out file)

[morning21]

Yesterday, I run Linux on FPGA with BOOM-core successfully. While I want to learn how the tool-chain works out, I surprisingly find that I cannot generate .out files.

Here is the output: ` [lipn@lipn-P50 ~/Software/rocket-chip/emulator]make output/towers.riscv.out

mkdir -p ./output

ln -fs /home/lipn/Software/riscv/riscv-tools/riscv/riscv64-unknown-elf/share/riscv-tests/benchmarks/towers.riscv output/towers.riscv ./emulator-rocketchip-BOOMConfig +max-cycles=100000000 +verbose output/towers.riscv 3>&1 1>&2 2>&3 | /home/lipn/Software/riscv/riscv-tools/riscv/bin/spike-dasm > output/towers.riscv.out && [ $PIPESTATUS -eq 0 ]

emulator-rocketchip-BOOMConfig: ../fesvr/dtm.cc:556: void dtm_t::producer_thread(): Assertion `get_field(hartinfo, DMI_HARTINFO_NSCRATCH) > 0' failed.

If there is any suggestion, please help me! Thanks a lot!

I clone rocket-chip and riscv-tools again in another PC. And the error appears:

emulator-rocketchip-BOOMConfig: ../fesvr/dtm.cc:556: void dtm_t::producer_thread(): Assertion `(((hartinfo) & ((0xf << 20))) / (((0xf << 20)) & ~(((0xf << 20)) << 1))) > 0' failed.

It appears you have a mismatch between your version of BOOM and the version of riscv-tools that you built.

Which riscv-tools did you build?

[morning21]

That could be the reason, I built the latest version of riscv-tools. I am cloning the riscv-tools in the rocket-chip directory. If there is any new progress, I will inform you soon. Thanks again.

It works out. Thanks!

Hello @BenjaminLpn I am facing the same issue but I couldn't understand how to overcome it. Could you please help me with fixing it. Thank you.

[morning21]

@manikantabhagavatula There may be a mismatch between your version of BOOM and the version of riscv-tools. The convenient way is to build the riscv-tools in your rocket-chip repo. Good luck.

@BenjaminLpn I have tried using the same version of BOOM and riscv-tools and it worked for me. Thanks alot. Also, is it possible to build riscv-tools necessary for both rocket (branch "master")and boom (branch "boom") on a single machine (within the same directory of /rocket-chip/riscv-tools)? To be more precise, Can I switch between rocket and boom using "git checkout master & git checkout boom" and compile programs simultaneously because I would like to compare the performance evaluation of both rocket and boom. Any input will be greatly appreciated.

@manikantabhagavatula Sure. As long as rocket and boom are switched in the same version, they can be compiled correctly with the same riscv-tools.
