I try to use eclipse to debug the project "Vexriscv.demo.GenFull" , and set the configuration like https://drive.google.com/open?id=1c46tyEV0xLwOsk76b0y2qqs8CYy7Zq3f, what's wrong with it?

Dolu1990 commented 1 year ago

Hi, what command are you using to run openocd ? which SoC are you targeting, on real hardware ?

ottotto335 commented 1 year ago

-c "set VEXRISCV_YAML /home/vexriscv/Desktop/VexRiscv_old/cpu0.yaml" -f /home/vexriscv/Desktop/openocd_riscv/tcl/target/vexriscv_sim.cfg i want to use verilator,what should I do?

Dolu1990 commented 1 year ago

Are you targeting a simulation ? or real hardware via usb jtag ?

ottotto335 commented 1 year ago

yes i'm targeting a simulation

Dolu1990 commented 1 year ago

Ahhh ok, which simulation testbench are you running exactly ?

ottotto335 commented 1 year ago

In the VexRiscv repository, to run the simulation on which one OpenOCD can connect itself =>

sbt "runMain vexriscv.demo.GenFull" cd src/test/cpp/regression make run DEBUG_PLUGIN_EXTERNAL=yes

In the openocd git, after building it =>

src/openocd -c "set VEXRISCV_YAML PATH_TO_THE_GENERATED_CPU0_YAML_FILE" -f tcl/target/vexriscv_sim.cfg

Run a GDB session with an elf RISCV executable (GenFull CPU)

YourRiscvToolsPath/bin/riscv32-unknown-elf-gdb VexRiscvRepo/src/test/resources/elf/uart.elf target remote localhost:3333 monitor reset halt load continue

I just follow this example in eclipse, using sbt in terminal to make the "cpu0.yaml" , then set up the configuration in eclipse with the rest of these commands

Dolu1990 commented 1 year ago

Hmm, did you used a absolute path for the """PATH_TO_THE_GENERATED_CPU0_YAML_FILE""" ?

ottotto335 commented 1 year ago

yes I replace it with the path on my pc, it's /home/591867/Desktop/VexRiscv/cpu0.yaml

Dolu1990 commented 1 year ago

So, i just tried on my side using your commands, and it seems fine. Here is the openocd logs when i run it :

I can then connect via telnet on it and do stuff.

You keept the "make run DEBUG_PLUGIN_EXTERNAL=yes" command runnig while you run openocd in another terminal ? (for now, don't add eclipse in the mix ^^)

ottotto335 commented 1 year ago

emmm I can also do this in terminal on my pc, but I'm asked to debug the project with eclipse . so actually I'm following this part ->"Using Eclipse to run and debug the software", and it isn't that clear, so could you please tell me how to set the configuartion in eclipse to run it?

Dolu1990 commented 1 year ago

Ahhh nice, that's already a good step. So if you get

It it maybe because you ran openocd twice ? once in the background, once with eclipse itself ? Personnaly, i'm not using eclipse to run openocd, i just let openocd run in the backgroud

ottotto335 commented 1 year ago

so I should let openocd run in the backgroud,and just use eclipse to run gdb? Then where should I print this command "make run DEBUG_PLUGIN_EXTERNAL=yes"? In another terminal or builder setting in eclipse?

Dolu1990 commented 1 year ago

That's the way i'm doing it yes.

Then where should I print this command "make run DEBUG_PLUGIN_EXTERNAL=yes"? In another terminal or builder setting in eclipse?

Another terminal ^^

ottotto335 commented 1 year ago

oh I see, thanks a lot!^^ one last question,when I run gdb in eclipse, where should I print the path of .elf file in this command -> YourRiscvToolsPath/bin/riscv32-unknown-elf-gdb VexRiscvRepo/src/test/resources/elf/uart.elf in Run->Debug Configurations->GDB OpenOCD Debugging->Debugger->GDB client Setup->other options I guess?

Dolu1990 commented 1 year ago

ahhh to provide the elf to eclipse run configuration : image

ottotto335 commented 1 year ago

ok get it ! that's all, thanks for your help!^
