Hi, I have already reflashed my board and connected it to the host. The ping action was successful and the debug stub was right. However, when I tried to connect the debugger to my board, it saied “Fail to connect ot linux debug target ‘169.254.5.244’ “Unable to connect to debug target at 169.254.5.244”. I found there was another post discribed a same situation as I faced at April and the author was Jialun_Liu, but the result seems not good. I runned all the commands adviced him to run, and got almost the same results as him did. It seems everything was right and I can ping the board which means the connction was successful. Could you please help me about this?
