My chip can only work with old gdb-5.0 "target jtag jtag://localhost:9999".
Can gdb-6.8 (or gdb-7.0) support it?

<p>
GDB 6.8 supports the old proprietary OpenRISC JTAG protocol, but this is deprecated. The recommended interface is the standard GDB Remote Serial Protocol.
</p>
<p>
Since all other projects are now using the standard Remote Serial Protocol, I do not believe the code for OpenRISC JTAG protocol in GDB 6.8 has been tested.
</p>
<p>
This protocol is now over 10 years old, and obsolete. It will be dropped in GDB 7.0.
</p>
<p>
The recommended solution is to migrate your interface to use the Remote Serial Protocol. The alternative is to use GDB 5.3, which is still available on the OpenCores website.
</p>
<p>
Note that GDB 5.3 is itself around 10 years old, so many features are not supported.
