can gdb-6.8 support old gdb-5.0 jtag? #72

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. </p> <p> Jeremy </p> <p> -- <br /> Tel: +44 (1590) 610184<br /> Cell: +44 (7970) 676050<br /> SkypeID: jeremybennett<br /> Email: <a href="mailto:jeremy.bennett@embecosm.com">jeremy.bennett@embecosm.com</a><br /> Web: <a href="http://www.embecosm.com">www.embecosm.com</a> </p>
