    can't program CYBT_333047-02 via HCI UART


      I tried to download the latest Wiced Firmware V1.1.14 received from here https://www.cypress.com/documentation/software-and-drivers/ez-serial-ez-ble-module-firmware-platform into my CYBT-333047-EVAL board but it failed with error "BluetoolDownloadMinidriver failed!"


      I installed WICED Studio 6.4 and all the necessary tools. I am using "Chipload.exe" tool to download the HEX file via command line interface.


      I also installed the plattform files needed for CYBT_343026 that is part of the EVAL board from here Platform Files for CYBT-343026-EVAL – KBA221025


      I plugged the USB port into my PC that gave me two UART ports COM8 and COM9. I am using the COM8

      The SW4 (HCI UART) positions 1, 2, 3, and 4 for HCI UART are ON.


      Here is my command line:


      C:\Users\armin\Documents\WICED\WICED-Smart-SDK-2.2.3\WICED-Smart-SDK\Tools\ChipLoad\Win32\ChipLoad.exe -BLUETOOLMODE -BAUDRATE 115200 -PORT COM8 -MINIDRIVER C:\Users\armin\Documents\WICED-Studio-6.4\20706-A2_Bluetooth\platforms\CYBT_343026_EVAL\UART.hex -BTP C:\Users\armin\Documents\WICED-Studio-6.4\20706-A2_Bluetooth\platforms\CYBT_343026_EVAL\CYBT_343026_EVAL_SFLASH.btp -CONFIG C:\Users\armin\Documents\WICED\WICED-Smart-SDK-2.2.3\WICED-Smart-SDK\Tools\ChipLoad\Win32\ezserial_343026-CYBT_343026_EVAL-rom-ram-Wiced-release.hex


      It says "BluetoolDownloadMinidriver failed!"


      What am I doing wrong?
