the processor with the JTAG Programmer/Debugger for ARM processors. I just don’t know where in what order and which pins to connect to the cable… any ideas?
ntrst dbgrq dbgrback vtarget. Also where do I connect the gnd pins? To the processor gnd or battery gnd? Does it matter if I connect all the gnd in a common bus on series and than on the processor or they have to be placed in different pins?
TDO TMI TMS TCK VREF NTRST RTCK all of them with the pin that has their name except NTRST that I matched it with TRST…
now there are the GND pins left Vtarget RST, OBGRQ OBGBACK left without a match.
I have 3 questions:
Do I just leave the Vtarget, obgrq, OBGBACK unconnected? What are they used for?
Can I create a single bush where all gnd pins will be connected and drooped of the battery gnd pole that supplies with power the processor or that would be a lethal mistake?
You said I can just use these pins u listed above, why there are more pins that their names match with the processor pins? Is there any chance that I will need to connect them on future for a specific reason?
They might be power and ground. I don’t use Eagle, try the CADsoft forum. I don’t trust anyone else’s parts, they often have errors so I create my own.
