> Hi,
> In the gdb/gdbserver scenario, gdb is not sending qSymbol packet when
> using "symbol-file", without "file" or "exec-file".
> The steps are:
>   start gdb (with no arguments)
>   (gdb) symbol-file <file>
>   (gdb) target remote <ip>:<port>
>   ->  qSymbol packet is not sent.
> If the "file" command  is used instead of "symbol-file", the qSymbol
> packet is sent to gdbserver.
> The question makes more sense in the following context: Using Eclipse and
> DSF -GDB Hardware Debugging . Here, Eclipse is not using "file", but only
> "symbol-file" ( as explained why here: [1] ).  This  makes qSymbol
> notification not working.
> My questions/comments:
> - In the above scenario, does make sense to enable qSymbol notification
