Hi,

I was trying to flash AIROC™ Bluetooth module CYBLE343072 Using FTDI USB-UART bridge while I tried to flash it showing the error 

Programming target device ...

Found serial port : COM43

Downloading FW ...
Failed to determine baud rate
Download failed

If the serial port was not detected, make sure no other program such as Client Control has the port open.

If you have issues downloading to the kit, follow the steps below:

Press and hold the 'Recover' button on the kit.
Press and hold the 'Reset' button on the kit.
Release the 'Reset' button.
After one second, release the 'Recover' button.
make[1]: *** [../mtb_shared/wiced_btsdk/dev-kit/baselib/20835B1/release-v3.3.0/COMPONENT_20835B1/make/recipe/program.mk:102: qprogram] Error 1
make: *** [../mtb_shared/core-make/release-v1.9.0/make/core/main.mk:434: secondstage_build] Error 2

Even though I tried recover reset method same error it getting. Can you suggest me to sort out this error.

Hello @SURYASUNDAR 

Are you using a CYBLE343072 EVAL or custom board ?

If custom connection with the FTDI chip, can you please share the connection diagram and a photo of the connection?

If you already tried Recovery procedure (with reset - recovery switches) and still facing issues, then mostly it will be a hardware connection issue. 

Regards,

Anjana
