Topic: jtag cable: buy or build?

The content of this topic has been archived on 24 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

I would like to avoid time consuming problems caused by defective parts or bad soldering in the jtag.

On the other hand, the jtag circuit seems simple to assemble / solder and I do not have to bother with an online purchase of a jtag cable.

Should I build a jtag cable or buy one?

build it wink
very easy i made mine and it works very well.... (juste wire and resistor, not with the buffer)

not too long the wires wink

Wire-and-resistor cables may work for some MIPS-EJTAG devices, but will not work for any device that uses DMA. Also, they may damage your parallel port. You really need the buffer.

The discussion might have continued from here.
