Hi Thanks for your reply I tried that and its working fine In fact, when BBB is not powered, I am able to see that the serial line between my laptop and BBB is working perfectly as a loopback When I power ON the board, loopback disconnects and then nothing is received on laptop (or nothing is transmitted from BBB)
Should I enable UART0 on BBB, I was thinking that ttyO0 is enabled by default and that I am able to transmit data to BBB Currently my BBB has Debian 4.6 (linux 3.8.13-beagle70) On Sun, Oct 4, 2015 at 12:56 AM, Przemek Klosowski < [email protected]> wrote: > If you suspect your USB serial converter, a quick test is to short the RX > and TX and check that whey you type in your minicom/hyperterm you see the > hardware echo it back (just make sure you don't set it up for local > software echoing). > > On Sat, Oct 3, 2015 at 2:14 PM, deepak srinivasan <[email protected]> > wrote: > >> Hi >> >> I had recently bought a Beaglebone Black rev C and was getting started >> following online tutorials >> I tried to setup basic serial communication with BBB through J1 serial >> connector >> >> I am able to transmit data from my laptop to BBB via serial line and I >> can see the data coming to /dev/ttyO0 successfully >> But receiving data from BBB is not working >> Only once receive worked where it showing just gibberish in terminal and >> after that it consistently failed to work >> >> dmesg or syslog doesnt show any errors >> I checked for basic continuity and my USB to serial converter doesnt seem >> to one causing issue >> >> Can anyone help me on this issue >> Thanks in advance >> >> regards >> deepak >> >> -- >> For more options, visit http://beagleboard.org/discuss >> --- >> You received this message because you are subscribed to the Google Groups >> "BeagleBoard" group. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to [email protected]. >> For more options, visit https://groups.google.com/d/optout. >> > > -- > For more options, visit http://beagleboard.org/discuss > --- > You received this message because you are subscribed to a topic in the > Google Groups "BeagleBoard" group. > To unsubscribe from this topic, visit > https://groups.google.com/d/topic/beagleboard/63k5jMJEhGE/unsubscribe. > To unsubscribe from this group and all its topics, send an email to > [email protected]. > For more options, visit https://groups.google.com/d/optout. > -- regards deepak 9962962016 -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
