JTAG chained startkits connected to XTAG2 misidentify

Postby pstnotpd » Sat Apr 05, 2014 2:53 pm

I finally found time to try a JTAG chain built from 2 startkits.

Booting this from JTAG still doesn't seem possible but debug through xgdb should be.

However, the chain misidentifies now.

Code: Select all

Available XMOS Devices
----------------------

  ID	Name			Adapter ID	Devices
  --	----			----------	-------
  0 	XMOS XTAG-2         	80f9zHY1	??G[2]->L[3]
In this topic about L16->U8 a same sort of message was received which was eventually found to be tools problem.

I'm running on 64bit ubuntu and the offered patch is a windows dll. Is such a patch also available for the linux version?

I'm also exploring a hotplug option but it would certainly be nice to get a proper debug chain working as well.

It does indeed look like the same problem. Running the same configuration on a W7 laptop with the patched dll applied shows:

Code: Select all

Available XMOS Devices
----------------------

  ID    Name                    Adapter ID      Devices
  --    ----                    ----------      -------
  0     XMOS XTAG-2             80f9zHY1        L[0..3]
Which is what I would expect
