Unable to query target part layout!!!
When I work with the xilinx edk(ver8.1), after buttoning down the download bitstream?, I want to make a bootloader from the external flas ,but a problem still baffles me all the time, when I pressed the ?progra flash memory?, here is the context showed to me..
-------------
Performing CFI Query on the flash part(s)...Processor started. Type "stop to stop processor XMD% ERROR: Flashwriter application reported an error: Unable to quer target part layout! Processor started. Type "stop" to stop processor Flashwriter terminating !
Done!
What causes this problem? And What should I do to solve the problem? The flash I use is AM29LV040B-70JC.
