A0 on Connect ME as GPIO

0 votes
Hi,

I use the the ConnectME module in my design and I have a problem with the DCD line (A0).
I use this port as GPIO to control a reset line of another microcontroller (With a pull up on the design). And when I boot with this line connected, I have a lot of BREAK condition (in fact my code keep on going into onccIntRd() ).
But I have configured the com port with
#define BSP_GPIO_MUX_SERIAL_A BSP_GPIO_MUX_SERIAL_2_WIRE_UART
and
#define BSP_GPIO_MUX_SERIAL_EXTERNAL_TX_CLOCK_A BSP_GPIO_MUX_INTERNAL_USE_ONLY
in gpio.h
I don't use other wire than TX/RX for the UART so I don't understand how break condition can append.

Thanks for any help !
