[SIS] Connecting to riscv-rtems6-sis via gdb

You also need to connect gdb with 'target extended-remote localhost:1234' . It should work then ...------ Ursprungligt meddelande------Från: Jan.Sommer at dlr.deDatum: tis 15 juni 2021 08:38Till: jiri at gaisler.se;users at rtems.org;Kopia: Ämne:RE: [SIS] Connecting to riscv-rtems6-sis via gdb

Unfortunately, this didn’t help:

 
Transfer rate: 4462 KB/sec, 236 bytes/write.
(gdb) run
The "remote" target does not support "run".  Try "help target" or "continue".
 
I also tried target extended-remote and the -r option in SIS, but so far without success.
 
Best regards,

Try to start ececution in gdb with 'run' rather than "c'. This might be needed to initialize the simulator.

Hello,

I tried to follow the example for using SIS, but use RISCV as the target platform instead of SPARC (https://docs.rtems.org/branches/master/user/tools/tester.html#building-rtems-tests).
However, while I can run ticker.exe of the griscv BSP perfectly in SIS, the same application does not run when loaded through gdb.

I did 
$ riscv-rtems6-sis -gdb 
SIS - SPARC/RISCV instruction simulator 2.26,  copyright Jiri Gaisler 2020

RISCV/GRLIB emulation enabled, 1 cpus online, delta 50 clocks

$ riscv-rtems6-gdb riscv-rtems6/griscv/testsuites/samples/ticker.exe
(gdb) target remote :1234

(gdb) c
Continuing.

If I run "riscv-rtems6-sis -r riscv-rtems6/griscv/testsuites/samples/ticker.exe" everything works like expected.
Am I doing something wrong?

Best regards,

    Jan
