I am using an ML605. I used Impact to erase the BPI flash device and do a blank check. Both succeeded.

When I attempt to do a "Read Device Status" under Impact, I get a red box message "ReadStatusRegister Failed"

The Flash device is a Numonyx P30.

The JTAG is operating at 3 Mhz (I reduced the TCK from 6 Mhz following some posts on the forum).

Any clues on how to overcome this ?

The impact log is as follows:

--------------------------------------

rahulrs84,

This post would be better served being moved to the Other Tools thread, as the issue appears in iMPACT, and is an iMPACT error.

However, I believe I can help answer this for you.

The problem here is you are trying to read the status register of the P30.  ReadStatusRegister in iMPACT is intended to be used to read the status register of Xilinx FPGAs, not third party flash devices.

For more info on the Status Register, please see Answer Record 24024: http://www.xilinx.com/support/answers/24024.htm
