a problem about TS101
in [DSP]
|
From: duke_winner on 13 Jan 2008 01:21 I have a problem about TS101 ,can somebody help me?Thank you The JTAG can scaned succesfully ,but there was a error happened when I uesed JTAG to do simulation ,that is 'An EMUIR scan was attempted ,but the dsp is not ready to accept instruction via JTAG'. I don't kown what's wrong with it.

The crux of it was that the ICE and/or the TS101 board were not in a state suitable for a JTAG session. I had to power down everything, and ensure that I powered up again in the right order, and that the TS101 cluster was in a suitable reset state to start a JTAG session. 'Chops

Is your mean the sequence of power 1.2V and 3.3V ? or else?

Unfortunately, the right order depends on exactly what you're connected to. I find that powering up the TS101 first, then the PC, and then the ICE, solved my problems. Also, I found that it was more likely to work if, after configuring my session in VDSP, I did not carry out any testsin the configurator but instead went straight to opening the session. 'Chops

Is your meaning is that if JTAG configuretor tests successfully ,there is no trouble with TS101 itself. |
