Oct 04 06:59:16 <Deepak> Hi
Oct 04 07:00:05 <Deepak> I am facing a problem when using serial communication via ttyO0
Oct 04 07:01:17 <Deepak> When board is not powered I am able to see the setup working as a loopback interface
Oct 04 07:02:27 <Deepak> But when its powered ON, I am not able to receive any data from BBB via the serial interface
Oct 04 07:03:02 <Deepak> any pointers on what I am doing wrong?
Oct 04 07:03:17 <Deepak> I believe ttyO0 is enabled desfault
Oct 04 07:05:05 <tbr> have you tried reversing RX and TX?
Oct 04 07:08:05 <Deepak> yeah I tried it, In that case even loopback when powered down doesnt happen
Oct 04 07:12:56 <tbr> what is the Vref of the adaptor you have connected to the port?
Oct 04 07:20:27 <Deepak> 3.3 v
Oct 04 07:21:31 <tbr> what is the operating system and version that you are running on the BBB?
Oct 04 07:24:15 <Deepak> Linux version : 3.8.13-bone 70
Oct 04 07:24:42 <tbr> and which distribution?
Oct 04 07:25:14 <Deepak> OS : Debian 4.6
Oct 04 07:27:44 <tbr> I doubt that it's running Etch
Oct 04 07:29:14 <tbr> guessing by the kernel package version, you might want to also reflash your board with an up to date image
Oct 04 07:31:38 <Deepak> oh! Thanks will try that
Oct 04 07:35:13 <Deepak> dogtag tells the one I have is a relatively new image (from 1st march 2015)
Oct 04 07:38:03 <tbr> mh, ok
Oct 04 07:38:14 <tbr> no need to update that then
Oct 04 07:38:28 <tbr> what's the baud-rate you've set in your terminal application?
Oct 04 07:46:31 <Deepak> I use 115200 as baudrate
Oct 04 07:51:21 <tbr> then you should get the boot output and the login prompt on it
Oct 04 07:54:22 <Deepak> I am not sure whats the cause of the problem
Oct 04 07:54:44 <Deepak> I am able to send data to BBB but reverse is not happening
Oct 04 07:56:04 <Deepak> As soon as I power ON the board, RXD on USB-TTL stops glowing and nothing can be seen on picocom
Oct 04 07:56:41 <Deepak> Immediately after I turn OFF, RXD glows again and it starts to act like a loopback
Oct 04 07:57:31 <tbr> and you have the RX pin on the converter connected to the TX pin on the board?
Oct 04 07:58:33 <Deepak> yes
Oct 04 07:59:08 <veremit> you can swap tx/rx .. theoretically it -should- be tx-tx and rx-rx according to spec :p
Oct 04 07:59:09 <Deepak> I checked if my USB-TTL is wrong and tried interchanging Tx and Rx
Oct 04 07:59:27 <veremit> make sure flow control is OFF
Oct 04 07:59:36 <Deepak> but in that case even loopback on power off is not working
Oct 04 08:00:04 <veremit> ok gotta fly .. good luck!
Oct 04 10:37:08 <zmatt> you can fly? cool
Oct 04 10:38:22 <zmatt> Deepak: there isn't *supposed* to be any "loopback on power off"
Oct 04 13:13:52 <Jackix> Hi, is anyone able to help me with installing the windows drivers for the BBB?
Oct 04 13:16:04 <tbr> what is your problem with that?
Oct 04 13:17:36 <Jackix> When i run the BONE_D64.exe it does not install any of the drivers it just goes to the end screen telling me the 4 drivers have failed. I have tried to run it as admin, extract the .exe and run dpinst.exe as admin and with no firewall.
Oct 04 13:19:16 <Jackix> I have read that some users have problems with the drivers beeing unsigned but since i do not get a warning/error telling me anything I do not know what the problem might be?
Oct 04 13:21:44 <tbr> hmm
Oct 04 13:22:20 <tbr> I never had to go through that, so I'm not sure
Oct 04 13:22:28 <tbr> which windows version?
Oct 04 13:22:37 <Jackix> Win 8.1 64-bit
Oct 04 13:23:40 <tbr> I think someone made a signed version, you could try that
Oct 04 13:24:14 <tbr> https://github.com/jadonk/beaglebone-getting-started/tree/sysco-ch-signed-drivers/Drivers/Windows
Oct 04 13:26:28 <Jackix> I have not tried them since the signature expired, but they are working on a getting them signed again. Quote RobertCNelson: "Still waiting on GoDaddy for and update certificate, so we can 're-sign' them.. " 1.Oct
Oct 04 13:26:35 <tbr> ah
Oct 04 13:27:10 <tbr> you could extract the drivers themselves (probably just a bunch of inf files)
Oct 04 13:27:39 <tbr> and try installing them in safe mode(?). I remember there was a way around the signature check
Oct 04 13:28:44 <tbr> https://learn.sparkfun.com/tutorials/disabling-driver-signature-on-windows-8
Oct 04 13:29:46 <Jackix> Hehe, Yes I have looked at that but the options/interface in windows changed in 8.1 so we do not have those settings anymore
Oct 04 13:30:21 <tbr> duh
Oct 04 13:30:28 <Jackix> Atleast not where the guide says they are.
Oct 04 13:31:12 <tbr> so that is not valid? - NOTE: In Windows 8.1, the ‘Restart Now’ button has moved to ‘PC Setting -> Update & Recovery -> Recovery.’
Oct 04 13:31:53 <Jackix> Ohh sweet! I missed that, I will definitely try that :D
Oct 04 13:32:17 <Jackix> Thank you alot for your time and help
Oct 04 13:33:35 <tbr> np
Oct 04 13:36:13 <graeme61> help
