Hi, I am new to rocketchip and am trying to run a helloworld using emulator. I am getting the error and the system is halted. Error: "tohost and fromhost symbols not in ELF; can't communicate with target"

I run this command: ./emulator-freechips.rocketchip.system-DefaultConfig helloworld ......... Debug Abstract Command Error #3 (EXCEPTION)ERROR: ../fesvr/dtm.cc:347, Should die, but allowing simulation to continue and fail.ERROR: ../fesvr/dtm.cc:346, Debug Abstract Command Error #3 (EXCEPTION)ERRORwarning: tohost and fromhost symbols not in ELF; can't communicate with target

Please suggest me how to solve it. Any suggestion will be appreciated very much!

Have you run it on Spike before trying to run it on RTL simulation?

In both cases you probably need to use the proxy kernel. i.e. ./emulator pk a.out or spike pk a.out, rather than ./emulator a.out or spike a.out

I tried to set up the riscv-tool so it took me that long to answer your question. Sorry for that! I am trying to run on spike , however I am not able to make spike pk run as it gives some error. I tried to run : riscv-tools$riscv64-unknown-elf-gcc -march=rv64gc -mabi=lp64 -o hello11 hello hello: file not recognized: file format not recognized collect2: error: ld returned 1 exit status

Please help me solve this.

@ferdous313 read your error carefully. You probably meant "hello.S" or "hello.c" at the end instead of a bare "hello". That way GCC knowns which stage to feed id
