Virtex4 : Downloading error

I created microblaze design using bases system builder for virtex 4 lx25 lc board using Xilinx EDK 7.1i sp2.

After downloading, when using xmd to connect, the following error happens..

JTAG chain configuration -------------------------------------------------- Device ID Code IR Length Part Name 1 0167c093 10 XC4VLX25 Assuming, Device No: 1 contains the MicroBlaze system WARNING:EDK - MDM Peripheral Not Detected on Hardware WARNING:EDK - Assuming opb_jtag_uart peripheral Connected to the JTAG MicroProcessor Debug Module (MDM) No of processors = 1

UNKNOWN Processor Version (0) Verify if FPGA Bitstream was downloaded and DONE pin went High

FPGA bitstream was properly built and downloaded to the system.

likely possible causes : 1. JTAG cable 2. EDK downloading issue like the ise 7.1i doent program single virtex4 devices after sp3

Any advice.

Thanks

hi

For vitex4 devices you are required to use the latest cvs version of
mdm (2.01.a). The file can be download from xilinx's answer database
(link below), it also tells you how to solve this problem.
