HELP! I've made a board using C5402 uBGA package. It's so difficult to solder the chip to my board. Evenworse, after soldering, the code composer said : "cannot initialize target DSP, time out on target processor ..." :(( To test whether the DSP is well soldered, I just connected the 3.3v power, the regulator, crystal circuit and CLKMD pins. What else is necessary to get the emulator work on my DSP? I've tested some of the output pins, they were at high level as defined. Unfortunatly, the CLKOUT was disconnected in my circuit so that I cannot test this pin. A big lesson! Could any body using Code composer tell me what may cause that error message "cannot initialize the DSP"? Or any idea about how to test the DSP -- I just need to know whether the pins are well connected to the pads. THANKs in advance! Wish I had designed with the TQFP pakage :-( Have a nice weekend! liyi |
