Hallo, I try to use urjtag to load a svf file generated by Xilinx Impact into a Digilent nexys2 board via JTAG interface provided by the EZ-USB FX2LP controller and the usbblaster emulation from ixo-jtag.
The chain is essentially the one given by nexys2prog, the .bit file is converted to a .svf file by Xilinx impact, than loaded with jtag. It works, the DONE led is on and the design works, but I always get an error message Error svf: SIR command length inconsistent. It is caused by the second last svf command SIR 14 TDI (3fff) SMASK (3fff) ; This effect has been discussed briefly before, e.g. in http://sourceforge.net/projects/urjtag/forums/forum/682993/topic/4006306?message=8912598 but it is not clear to me what's wrong here. I added some more info to the error message to find out the the message is issued because priv->ir->value->len is 6 len is 14 It's obvious that the length field as well as the constants involved in the failing SIR command are 14, and it's not clear to be the svf engine expects something of length 6 here. Any hint and/or help is very welcome.

It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense.
