Error: target 'fpga_spinal.cpu0' init failed #34

Hi, what command are you using to run openocd ? |
|
-c "set VEXRISCV_YAML /home/vexriscv/Desktop/VexRiscv_old/cpu0.yaml" -f /home/vexriscv/Desktop/openocd_riscv/tcl/target/vexriscv_sim.cfg |
|
Are you targeting a simulation ? or real hardware via usb jtag ? |
|
yes i'm targeting a simulation |
|
Ahhh ok, which simulation testbench are you running exactly ? |
|
#In the VexRiscv repository, to run the simulation on which one OpenOCD can connect itself => #In the openocd git, after building it => #Run a GDB session with an elf RISCV executable (GenFull CPU) 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 |
|
Hmm, did you used a absolute path for the """PATH_TO_THE_GENERATED_CPU0_YAML_FILE""" ? |
|
yes I replace it with the path on my pc, it's /home/591867/Desktop/VexRiscv/cpu0.yaml |
|
So, i just tried on my side using your commands, and it seems fine. Here is the openocd logs when i run it : Open On-Chip Debugger 0.11.0+dev-02583-g9d50e3c2f-dirty (2022-10-27-11:30)

|
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? |
|
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 ? |
|
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? |
That's the way i'm doing it yes.
Another terminal ^^ |
|
oh I see, thanks a lot!^^ |
|
ahhh to provide the elf to eclipse run configuration : |
|
ok get it ! that's all, thanks for your help!^ |

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?
