    Hi. Sadly, manual setup still shows reading zero blocks when executing “x/16xb” gdb command. I also tried some “mon mdw <address> <count>” commands, but looking at module list block I only find:

    Just to be sure JTAG is working as expected I also tried to run a mon mdw at a different address I spotted in gdb trace, and there I can find some “non-zero” content:

    0xc001d4d4: e1a00000 e1a00000 e1a00000 1afffff7 e12fff1e ee070f3a e2800020 e2511020

    0xc001d514: ee0d1f30 e12fff1e 00000000 00000040 00000008 0000000c 00000004 00000000
    0xc001d534: 00000000 0000004c 00000000 00000040 00000000 0000000c

    Is there any other board I could try? I’m using a RPi 1, since it seems that RPi3 is not supported by my J-Link (V8), but I have plenty of other arm-based linux embedded devices I could try with.

    Thanks!

    Hi. I tried same test on a VMWare virtual machine target, and it works a treat!

    Thanks.

    Putting “mon sleep 3000” only after target  remote command “command not supported by this target” issue is solved, but I still get the original issue.

    Please find gdb and OCD logs as attachments.

    Thanks.

    Hi. Sorry for my delay.

    Sadly “mon sleep 3000” returns on GDB session log “&”\”monitor\” command not supported by this target.\n””

    …I don’t know if it is relevant, but the last line I can read on VisualKernel Program Output (just below log line printed by module_init function) is “rfkill: input handler disabled”.

    I tried with both 500KHz and 100KHz, but with no luck.

    You can find gdb and ocd session logs as attachments (for 500KHz session).

    Thanks.
