[ECOS] How to use redboot as a GDB stub?!

[张晖]

Hi, all

I have built redboot from the lastest CVS, and it can boot my target pc very well, I try to connect to the target with hyperterminal, it also work, I see the command prompt on hyperterminal; But when I use gdb to connect to the target, I failed, I have set baudrate to 38400 8n1;

I know that the redboot should be switched to the stub mode, but how to? anyone help me? Thanks.
