Hi,
I am new to Cypress development kits, As per our understanding CYW4343 is an integrated combo chip, which supports BLE + WiFi.
And this chip can be access by STM32F4 family.
But we are facing the below issues while working with CYW94343WWCD1_EVB platform.
Issue 1:
We have tried to build the target: CYW94343WWCD1_EVB (Board contains CYW4343W + STM32F4) which is available in WICED Studio 6.4.
Which is not successful and observed the below errors:
Downloading Bootloader ...

**** OpenOCD failed - ensure you have installed the driver from the drivers directory, and that the debugger is not running **** In Linux this may be due to USB access permissions. In a virtual machine it may be due to USB passthrough settings. Check in the task list that another OpenOCD process is not running. Check that you have the correct target and JTAG device plugged in. ****

make: *** [main_app] Error 2
Issue 2:
We tried to build the Demo applications bt_wifi_introduce and wifi_onboarding, but no luck.
Got the following errors.
"Host mode"
./tools/makefiles/wiced_config.mk:433: *** ble_wifi_introducer application does not support CYW94343WWCD1_EVB platform. Stop.
make: *** No rule to make target `build/demo.ble_wifi_introducer-CYW94343WWCD1_EVB-FreeRTOS-LwIP/config.mk', needed by `main_app'. Stop.
Could you please let us know whether CYW4343W have support for WiFi+Bluetooth?
Let us know what are the suitable demo application to start work on WiFi and Bluetooth on CYW94343WWCD1_EVB platform and let us know how to build them.
Solved! Go to Solution.

Hi,
Yes, CYW4343W is an integrated combo chip and have support for both Wifi and Bluetooth.
Please use string BCM94343WWCD2 instead of CYW94343WWCD1_EVB in make target.
Can you please try with below build strings in make targets and let us know if you're facing any issues.
Issue 1 : snip.scan-BCM94343WWCD2-FreeRTOS-LwIP download run
Issue 2 : demo.ble_wifi_introducer-FreeRTOS-LwIP-BCM94343WWCD2 download run
Thanks.

Hi Kotnanik,
Thank you for your help.
Now we could build sample Bluetooth/WiFi application by using "BCM94343WWCD2" (43xxx_Wi-Fi/platforms/BCM94343WWCD2).
Binaries generated below:
snip.bluetooth.ble_hello_sensor-BCM94343WWCD2-FreeRTOS-LwIP.elf
snip.bluetooth.ble_hello_sensor-BCM94343WWCD2-FreeRTOS-LwIP.map
snip.bluetooth.ble_hello_sensor-BCM94343WWCD2-FreeRTOS-LwIP.bin
Actually we are planning to use BCM4343W with STM32F4 family(CYW94343WCD1_EVB).
Is the above generated binaries are enough to handle STM32F4 MCU + BCM4343W Chipset or we need to flash another firmware for STM32F4 MCU separately.
Please share us your valid inputs or any reference document.
Thanks

Hi,
I wonder, where did you get the demos for the CYW94343WWCD1_EVB?
Thanks, James Osborne

Hi,
Please check the video tutorials to get started with WICED Wiced Training Videos & Getting Started .
You can find demos & snip applications in the 43xxx_Wi-Fi/apps path and the relevant documents under 43xxx_Wi-Fi/doc section in the WICED.
Thanks.
