Does the communication between gdb and compiled-in target simulator follow any rules? for example,there is "remote debug interface " between gdb and ARMulator,and "remote serial protocol"between gdb and remote target. the compiled-in simulator receive the command from gdb command line interface and return the info to gdb.how to deal with the procedure?Is there any protocol? _________________________________________________________________ ÏíÓÃÊÀ½çÉÏ×î´óµÄµç×ÓÓʼþϵͳ¡ª MSN Hotmail¡£ http://www.hotmail.com
