Hi,
I'm working on using openOCD on an Altera target using the Virtual
JTAG. It is working but it is very very slow
This is the log from the -d 3 output when issuing a x/4xw 0 command with gdb:

So if you (julius ?) have an idea to save me some time debugging this
(full log here http://pastebin.com/NxxNnrSy) .....
How fast it is when using your JTAG chain ?
Thanks,
Franck.
BTW: using the vjtag, the data from dbg_if were always 1 bit shifted.
I used this fix:
always @ (tdo_tmp/*negedge tck_i*/)
begin
tdo_o <= tdo_tmp;
end
However, I need to take I deeper look at this to see who is right
(vjtag or generic_tap).
