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?
