Hi,

I need help to get started with cyw2071b1kumblg, I have used it on a custom board and I am not able to check whether it is working or not and following are the reasons.

1. I am not able to find the SDK provided by Cypress for this Soc also there is no option in the WICED-Studio for selecting the board support package like they show in the user guide.

2. I downloaded the CyBlueTool from here and when I send the reset command there is no response from the chip.

03/23/21 16:15:26.542 com9@115200 c> Reset
HCI Command
com9@115200
[03 0C 00 ]
opcode = 0x0C03 (3075, "Reset")

Could someone help me with the debugging and making the Soc to work?

PS: Any links to the useful resources will be highly appreciated.

Thanks,

Parth

There are two UART- HCI and Peripheral UART.

HCI UART is used for programming the device. You can check more details in CYW20719 datasheet section 6.

We have an evaluation board for CYW20719- CYW920719Q40EVB-01. You can refer the connections of this board and try to replicate the same on your custom board. Pin configurations can be checked here- /20719-B1_Bluetooth/platforms/CYW920719Q40EVB_01
