Hi everybody,

I have a board of Wiggler JTAG (LPT), I want to programmable TI C2000 but I can't connect my device. What must I do? Pls help me.

Thanks.
 

Hi,
The first thing you have to do is to check whether or
not your wiggler works well.
Check the circuit and pcb carefully.Maybe the problem just results from a wrong used risistor.
Then pull the inputs of 74HC244 to Vcc and Gnd and measure the outputs with a voltmeter to see whether they gives the correct response.
Then,if the problem still exists,see the settings of the software(LPT address,target setting,etc.).
Good luck!
