<pre class="moz-quote-pre" wrap="">I have attached the sis manual. Page 17:
"SIS can be connected to gdb through a network socket using the gdb remote interface.
Either start SIS with -gdb, or issue the ’gdb’ command inside SIS, and connect gdb with
’target extended-remote localhost:1234’. The port can be changed using the -port option."
You still need all other options, so to start on a windows host do:
$ riscv-rtems-sis -riscv -nouartrx -gdb
To start gdb, do:
$ riscv-rtems-gdb app.exe
(gdb) target extended-remote localhost:1234
(gdb) load
(gdb) run
To re-run the application, issue a new load command first.
Regards, Jiri.
