Can't read ID of external flash memory

Hello everyone.

I have Artix XC7A35 and external flash memory Macronix MX25R3235F, which is x1/x2/x4 32Mb Flash memory.

This part is absent in supported device list, but replaced it with mx25l3233f-spi-x1_x2_x4.

After generation an mcs file i'm trying to programm and getting following message.

Mfg ID : 0   Memory Type : 0   Memory Capacity : 0   Device ID 1 : 0   Device ID 2 : 0
CRITICAL WARNING: [Labtools 27-2251] Unable to read device properties. Please make sure that the proper configuration memory part is selected.

I've tried that both in x1 and x4 modes.

We checked connections with osciloscope, D0 and D1 are toggling, CS goes low for the transaction and CCLK creates clock bursts.

Is it possible to configure FPGA from such memory and if the answer is yes, why am I failing to so?
