Could not determine GDB version using command:
My solution to a similar problem was to install the distribution’s arm-eabi-none-gdb package, which Fedora thoughtfully provide separately from cross compiler sutie.
I can still rebuld the project so it seems that the rest of the tools do not have any similar dependency issues.
I then point to the working gdb using : Run->Debug Configurations->Debugger
However, it is now OpenOCD which fails.
__
in procedure ‘program’
in procedure ‘init’ called at file “embedded:startup.tcl”, line 473
in procedure ‘ocd_bouncer’
- OpenOCD init failed **
shutdown command invoked__
Not very helpful error trapping in ‘ocd_bouncer’
It looks like this AC6 product is starting to suffer from bit-rot.
