I am new to Blackfin. I have just bought a ADZS bf527 ezlite and connected it with my pc using a serial cable. I have set up hyper terminal for 57600 baud 8N1 parity none flow none. After powering up i was expecting Uboot messages. But i have got nothing. I have tried every boot mode. But it shows nothing on hyperterminal. SW10 is like this off,on,off,off ,off,off,off,off. Can anyone tell me what am i doing wrong.
