I'm a Beginner, So I don't know much about this. Please correct me if I'm wrong.

I have downloaded platform files and firmware files. I'm using ChipLoad to flash.

This is the output I get when using COM6, and as per the schematic, it is HCI UART.

@E,003B,BOOT,E=01010E06,S=05020016,P=0103,H=D1,C=00,A=E45A59737646<CR><LF>
@E,000E,ASC,S=01,R=03<CR><LF>

I have connected the board correctly. But still, it fails.

Commands Tested:

Hi SuPa_4844796 ,

Hope you have selected HCI UART port correctly.

Make sure it is not opened in Teraterm or any other console while trying to download the FW. If then please close the other consoles and make sure only chipload tool is using HCI UART com port.

From the logs which you have shared, seems like you just gave the file names, not the absolute path. Make sure you provide the complete path of minidriver , btp , hex files. For example, refer here: Programming Using Chipload.exe - KBA228316

You can also try once programming the module directly from the SDK or using WICED module programmer available here: WICED Module Programmer User Guide – KBA225060 . So that you can ensure the FW is downloading properly to your module or not.
