STEVAL-IDB007V1- Virtual com

 

I have reprogrammed the STM32L151CB on board with the following two file:

EVAL_IDB007\BlueNRG_GUI_2_2_2\Firmware\STM32L1_prebuilt_images\DFU_Bootloader.hex

EVAL_IDB007\BlueNRG_GUI_2_2_2\Firmware\STM32L1_prebuilt_images\BlueNRG_VCOM_1_8.hex

I used J-link with J-flash from segger and CN6 JTAG connector on board.

The two programming step from 800.0000 and 800.2fff for the bootloader and from 800.3000 for the

VCOM_1_8 are OK (program&verify).

But the VCOM doesn't appare and DL2 led is alway in red state.

 

Where the procedure is wrong?

Thank in advance.
