*I need some clarification about BeagleBone.*
*Currently working in Serial communication and configured UART-1 [ P9_24
=TXD , P9_26 = RXD ] and UART-2 [ P9_21 =TXD , P9_22 = RXD ] in this
pins.*
*I can transmit and receive data from UART_1 to UART_2 and vice verse
using simple wires ( see image 2).*
*Now i try to communicate with external device using CP2102 USB to TTL
serial converter 3.3 volts ( image 1).*
*I have connected TXD (P9_24) pin of BeagleBone to RXD of converter and
RXD (P9_26) pin of BeagleBone to TXD of converter. *
*After this connection made , BeagleBone board's power off and stopped
working .*
*may i know why this problem happens , please help me o find out the
solution to overcome this problem. *
*The voltage levels have been checked for 3.3 v and the connections were
verified. Adaptor Ground --> BB Ground Adaptor TX --> BB RX of uart1Adaptor
RX --> BB TX of uart1*
