remote target: single step too slow


Hi,
I found in the last version of gdb next stange effect:
after breakpoint the gdb read the code memory from the beginning of the current function in single word mode. This make the single stepping very very slow.
Why it is necessary gdb to read code after each breakpoint or single step?
If it is necessary is it not possible to read the code in block mode (one packet transaction with remote target)?


My platform:
CPU: ARM7TDMI, arm-elf
Remote target: BDI2000


best regards ilko iliev
