Description:
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?

GDB 6.8 supports the old proprietary OpenRISC JTAG protocol, but this is deprecated. The recommended interface is the standard GDB Remote Serial Protocol. 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. This protocol is now over 10 years old, and obsolete. It will be dropped in GDB 7.0. 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. Note that GDB 5.3 is itself around 10 years old, so many features are not supported. Jeremy
