Please add VERBOSE=1 in your make target and you will see more information about the download.

You can also refer to the following KBA for how to download FW with command line. Programming an EZ-BT WICED Module – KBA223428

Hi OwenZ_26:

I use the chipload to download the CYW20735  firmware,

ChipLoad.exe -BLUETOOLMODE -PORT COM10 -NOVERIFY -MINIDRIVER minidriver-20735B1-uart.hex -BTP 20735_SFLASH.btp -CONFIG mesh_light_ctl_server-CYW920735Q60EVB_01-rom-ram-Wiced-release.hex

but there is a error:

Downloaded 0 code bytes ( 0.0%) and 0 data bytes ( 0.0%). Verified 0 code bytes ( 0.0%) and 0 data bytes ( 0.0%).   Current state: Initialized

Downloaded 0 code bytes ( 0.0%) and 0 data bytes ( 0.0%). Verified 0 code bytes ( 0.0%) and 0 data bytes ( 0.0%).   Current state: Terminated with error

when I use the wiced studio to download firmware, it is ok.

Hi Mandy,

Please note you need to give complete path for minidriver and hex files .

Please have a look here: Programming using ChipLoad.exe

Also please refer to WICED_HCI_Control pdf for the steps for HCI UART programming.

Anjana
