Hello,
I am using the virtual_jtag megafunction to establish a communication between my computer and my dev board.
It seems that the value I read on the ir_in output does not always correspond to the value I sent via the tcl function device_virtual_ir_shift. For 1 and 2-bit wide virtual_ir, everything is fine but with a 3-bit wide virtual-ir, here is what I obtain :
Value sent | Value read on ir_in
000 | 000
001 | 001
010 | 000
011 | 001
100 | 100
101 | 101
110 | 110
111 | 111
It is even worse with 4 bits.
Do you have any idea where this could come from?
Thank you,
Zenzen
