eMMC device access problem with ZYNC FPGA

The design includes the XILINX ZYNC FPGA device (XC7Z035-2FFG900I) and the eMMC device connected to it (GreenLiant GLS85VM1064B-M-I-LFWE-N).

Attempts to test eMMC device connectivity using the JTAG test model (JTAG Technologies Provision software) were unsuccessful. Errors indicate that the CMD line is busy (always high).

Attempts to access the device using VIVADO and iMPACT were also unsuccessful. Please see the attached files.

What could be the problem?

Re: eMMC device access problem with ZYNC FPGA

Well, We're succeed to erase FPGA by iMPACT, but anyway the JTAG test is failing due to CMD line is stuck at High.
