Are you using the USB to power your target. When USB current limit is exceeded, it turns off than back again. If this is the case and you have not shorts or damaged parts, use an external pwr supply .<BR /><BR />Good luck.<BR /><BR />Cheers,<BR /><BR />Celso<BR /><DIV></DIV></BODY></HTML> Thu, 18 Dec 2008 21:42:26 GMT https://community.nxp.com/t5/8-bit-Microcontrollers/USB-LIGHT-BLINKS-IN-DEMO9S08QG8/m-p/211201#M18126 celsoken 2008-12-18T21:42:26Z Re: USB LIGHT BLINKS IN DEMO9S08QG8 https://community.nxp.com/t5/8-bit-Microcontrollers/USB-LIGHT-BLINKS-IN-DEMO9S08QG8/m-p/211202#M18127 <HTML><HEAD></HEAD><BODY><DIV></DIV>I've connected an external power supply; now the debbuger detects the demo, but it doesn't connect; it says:"MCU reset line: LOW". However, the light of Vdd is nearly invisible, but it's on and blinking. What's the problem now?<BR /><DIV></DIV><BR /><BR />Message Edited by KATBACK on <SPAN class="date_text">2008-12-18</SPAN> <SPAN class="time_text">02:23 PM</SPAN></BODY></HTML> Thu, 18 Dec 2008 22:22:54 GMT https://community.nxp.com/t5/8-bit-Microcontrollers/USB-LIGHT-BLINKS-IN-DEMO9S08QG8/m-p/211202#M18127 mmm 2008-12-18T22:22:54Z
