Hi all:
as we know, the wiced studio can download the firmware for CYW20735 by the uart., however this way to download firmware is not applicable to the Factory firmware burning. so we should develop a Host computer for firmware burning. firstly ,I need
to know how the wiced studio download the firmware, the console output messages is below when I use wiced studio to download firmware:
Detecting device...
Device found
Downloading application...
Download complete
Application running
where I can get the code of firmware downloading!
thanks!
Mandy

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

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
