Hello guys, I'm trying to debug with vscode (1.131) + cortex-debug (1.13.0-pre9) +nuclei studio toolchain riscv64-unknown-elf (202510). Windows 10 pro as a host system, jtag probe connected with USB. Debug console has a lot of output, terminal console is _empty_ except "PS C:\1\gh\pnfm>" line. So there is no sense in "Please check TERMINAL tab (gdb-server) for output" message. Last line of debug console is ~~~ "Failed to launch jlink GDB Server: Error: connect ETIMEDOUT 127.0.0.1:55878" ~~~ Checked with netstat -aon | findstr ":55878" - there is a vscode process on this port, respawns in case of end task from task manager. ~~~ `Cortex-Debug: VSCode debugger extension version 1.13.0-pre9 git(d793ce2). Usage info: https://github.com/Marus/cortex-debug#usage INFO: A log of gdb-servers, gdb, debug adapter start/stop/pid info can be found in 'C:\Users\***\AppData\Local\Temp\cortex-debug-server.log'.
