Hi all,
I have UrJTAG detecting properly my scan chain of 8 TAPs, last one being
chip-level TAP not related to any core itself. However, this TAP has ID of
0x0 (it does not have specific ID).
jtag> detect
IR length: 50
Chain length: 8
...
Device Id: 0 (0x0000000000000000)
I want to put certain command into IR of this TAP.
How can I do it ?
Firstly I thought to define it in MANUFACTURERS, PARTS and STEPPINGS... But
I can not do it, as TAPs are refered by ID, and this one does not have it.
That's why when I do :
jtag> print chain
No. Manufacturer Part Stepping Instruction
Register
------------------------------------------------------------------------------------------------------------------
...
7 (none)
(none)
jtag>
and I can not use this sequence :
jtag> part 7
jtag> instruction DEBUG
jtag> shift ir
as I would like to...
Is there some way to affect this TAPs IR even though it does not have any
ID ?
BR,
Drasko
