P2020 power on

[billy_huan]

Hi freescale：

Our new design uses QorIQ P2020, HW design is based on P2020RDB_Schematics REV: D.

Now when we power on, we can't connect P2020 through JTAG, the debug tools is usb tap cold warrior IDE, software is classic 8.8.

The Asleep is high and Ready Pin is low.

Is there any way that can help me to locate the problem?

B.R.

Hi Billy,

I am not working for Freescale, and I could be completely off with my suggestion, but first thing I would check is the TRST signal. Second I would check the USP tap firmware version, make sure it is the latest.

This is my two cents.

Hi Francois,

The thanks maybe a little bit late, but thank you all the same for your suggestions.
