Hi,

Wiggler <-> Dockstar

Hi,

I really have no idea.

all the howtos dont conect vcc from jtag to dockstar, so i didnt either.

the jtag has 5v pin1 vcc. Its written here min 2.7V and max 5V, recommended operation conditions.
Does that mean that i can connect it dockstar?

on this pic actualy it is connected but only 3,3V

Hi,

i found on the net that usb2lpt cables wont work with jtag. so i suppose that is the reason.
Will have to look for an lpt pci card.

till then.

thanks for your help

Hi,
i bought a pci lpt card, but it still doesnt work.
I tried it with srst connected without it, with vcc and with out.
How do i see if the jtag is working or where to search for errors?

is this port setting correct?

io range d880-d887
d800-d807
