BLUENRG-2N does not work.

[Vandr.1]

Communication with the chip BLUENRG-2N goes through SPI. When Chip Select GND, there is no interruption on IRQ line, all voltage and quartz are in order. Then I stitched through the SWD and the BlueNRG-1 ST-Link Utility program first with the BlueNRG_2N_Updater.bin firmware and with the address 0x10040000, then with the firmware BlueNRG_2N_FW_V3_2_0.bin and the address 0x10042000, and after that,I get this on a pin IRQ like the picture. Tell me what could be the problem, maybe I'm not flashing it correctly?

The both firmware images are correct, and the addresses are correct too.

Could you doubly check that neither UART bootloader nor updater shall be activated?

(Check the voltage level of DIO3 and DIO7 during powering up)
