I know that during debugging program in flash only HW breakpoints are enabled. I tried to set breakpoint in gdb via command "break" and "hbreak" also. In both case I have observeeed the same behaviour (SIGABRT after stepi and "*** TARGET: all hardware breakpoints in use " in the telnet session window). I've tried HWBP option instead of JTAG when chosing the stepmode for BDI 2000.
Are you sure you have hardware breakpoints on that target? And if you do, isn't that breakpoint (it's probably only one available) already used maybe? Check the BDI and Au1000 docs.
Also, maybe you should try commenting VECTOR CATCH. That signal looks funny to me.
