problem on work-ver/Variane_testharness rv64um-v-divuw

[vulkomilev]

After the step

make verilate DEBUG=1

on step

work-ver/Variane_testharness rv64um-v-divuw

i get the following error

This emulator compiled with JTAG Remote Bitbang client. To enable, use +jtag_rbb_enable=1. Listening on port 41909 Variane_testharness: ../fesvr/elfloader.cc:21: std::map<std::__cxx11::basic_string, long unsigned int> load_elf(const char*, memif_t*, reg_t*): Assertion `fd != -1' failed.

I am on ubuntu 20.04

I am getting the same error after I managed to make the binary after a lot of tinkering around. The binary refused to be made for any verilator version>4.20. The versions I have are riscv64-unknown-elf-gcc=>11.1.0 and verilator v4.014 . I have tried other older versions of verilator (e.g., 4.002, 4.004) but every time I got the same error as @vulkomilev . Unlike him I am using a Ubuntu 16.04 VM

Hi, @vulkomilev @hasanalshaikh @FranDuqueAyachi , I also have the same error. Have you fixed it?

Hello @hhhsiang, @FranDuqueAyachi, @hasanalshaikh and @vulkomilev. What is your current status?

By following the instructions in the top-level README I am able to compile without issues. I am using Verilator 4.100, and $RISCV/riscv64-unknown-linux-gnu-gcc -v yields the following:

Using built-in specs.

Hi @MikeOpenHWGroup I tried the command under cva6：$RISCV/riscv64-unknown-linux-gnu-gcc -v it showed：-bash: /riscv64-unknown-linux-gnu-gcc: No such file or directory

The followings are the steps I build the environment： At first, I used these command to checkout the repository under /home/aislab42190/：

git clone https://github.com/openhwgroup/cva6.git cd cva6 git submodule update --init --recursive after that, I build a new directory named "RISCV" under /home/aislab42190/ then I set the environment variable by these commands： 6. export RISCV="/home/aislab42190/RISCV/" 7. export PATH=$PATH:$RISCV/bin 8. source ~/.bashrc

to install all required tools： 9. ./ci/setup.sh 10. make verilate 11. make verilate DEBUG=1

after the above commands were executed, I use the command： work-ver/Variane_testharness rv64um-v-divuw

then it showed： This emulator compiled with JTAG Remote Bitbang client. To enable, use +jtag_rbb_enable=1. Listening on port 36327 Variane_testharness: ../fesvr/elfloader.cc:23: std::map<std::__cxx11::basic_string, long unsigned int> load_elf(const char*, memif_t*, reg_t*): Assertion `fd != -1' failed.

Did I have wrong during setting the environment variable path? I am running this on Ubuntu 20.04.

Thank you very much！

That means the path to your binary rv64um-v-divuw isn't good (wrong path, binary doesn't exist). It can't open the file descriptor.

[MikeOpenHWGroup]

Hi @hhhsiang, was @zarubaf's comment helpful? Are you still having trouble?

[hhhsiang]

@MikeOpenHWGroup ,the problem has been resolved. Thanks!

[MikeOpenHWGroup]

Thanks @hhhsiang, I will close this issue.
