There should be no issue that I know of. Maybe Ruedi can tell us if there is any known issue.

I have one breakpoint set, and when I try to step over a function call using the gdb "next" command, setting the breakpoint fails: # TARGET: breakpoint limit reached GDB displays this error message: Cannot insert breakpoint 0. Error accessing memory address 0x20008f0: Unknown error 4294967295. I have soft breakpoints enabled on the BDI (BREAKMODE SOFT 0xDFFFDFFF) and I'm setting soft breakpoints using gdb. I don't understand why there would be a limit on the number of breakpoints. If I 'set debug remote 1' then the final two packets displayed by gdb are... Sending packet: $m20008f0,4#5d...Ack Packet received: 021c3b1c Sending packet: $Z0,20008f0,2#a4...Ack Packet received: E03 Why did the soft breakpoint, Z0, command fail? What does the error code E03 mean? Does the BDI2000 differentiate between the soft breakpoint "break" command Z0 packet, and the hard breakpoint "hbreak" command Z1 packet?
