risc-v embedded gdb fails

[mrx23dot]

When I manually start it it works great riscv-none-elf-gdb.exe build\obj\proj.elf -ex "target extended-remote 127.0.0.1:3333"

but from VScode it prints this in Debug console, and exits, I can't even scroll in Debug console.

so looks like it founds it, I think I got the same config, so no idea. I added a break point to main() too.

my config:

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "by-gdb",
      "request": "launch",
      "name": "Launch(remote)",
      "debuggerPath": "riscv-none-elf-gdb.exe",
      "program": "..\\build\\obj\\proj.elf",
      "cwd": "${workspaceRoot}",
      "remote": {
        "enabled": true,
        "address": "127.0.0.1:3333",
        "mode": "extended-remote",
      }
    },
  ]
}

No issue when using PC type of gdb.

Could you print out the exact way gdb is called? (with absolute path to gdb, to know which one, and parameters)

that would be very useful, and give insight for future problems too.

[xuming]

It looks like the program is not correct . "program": "..\build\obj\proj.elf". sould be "build/obj/proj.elf" ?

[mrx23dot]

Same error with "program": "../build/obj/proj.elf",

also when I directly copy in proj.elf "program": "proj.elf",

for some reason it's not happy

~"For help, type \"help\".\n"
~"Type \"apropos word\" to search for commands related to \"word\".\n"
^error,msg="No symbol table is loaded.  Use the \"file\" command."
-gdb-exit
^exit

having the original gdb call printed would be helpful.

Also do you know why the output is not fully visible?
