Re: [beagleboard] Re: BBW not booting when serial to USB cable connected

2020-08-30 Thread Rishabh Kumar Gupta 
I found out the issue. I had used the wrong connections; connected 5V 
instead of ground!

After using the right connections, it worked even with the USB power.

Re: [beagleboard] Re: BBW not booting when serial to USB cable connected

2020-08-16 Thread rishabh . gupta777 
I got a DC adapter to power the board. Although the serial connection does 
not get dropped on powering up, I do not see the bootloader loading.

Some time back, I had managed to get access to the U-Boot bootloader on the 
serial terminal with the USB power itself. It didn't show up again. The 
behavior has not been consistent. Presently, the serial connection drops 
out if I try to power using USB.

I would appreciate any inputs to solve the issue.

Thanks Jon, for the link. I tried modifying my current driver installation. 
It still shows the same error. 

Although, now the board boots up but the serial connection gets dropped. 
The serial and power connections are somehow still mutually exclusive. The 
serial connection appears only when I turn off and plug out the micro-USB 
(power).

That error you are seeing appears to come from your USB to Serial interface.

Re: [beagleboard] Re: BBW not booting when serial to USB cable connected

2020-07-19 Thread jonnymo 
Are you plugging both USB cables directly to your PC or are you using a
Powered USB Hub?
I would suggest using a powered USB hub in this case if you were not using
one already or power the BBW via the barrel jack.


Cheers,

Try disabling the driver in win10 before starting virtual  box before starting 
VM then in Linux VM check which try enumerated and connect  to it was the fix I 
think.  With multiple USB devices it would change if I remember and you  might  
Google which VB version supports SUB best, Again that was several years

Re: [beagleboard] Re: BBW not booting when serial to USB cable connected

2020-07-19 Thread 'Mark Lazarewicz' via BeagleBoard 
Virtual Box support of SUB driver's was squirrelly 2 years ago.If I'm not 
mistaken at one point Mr Robert refused to support builds.
I was  able to get it to work but the flakiness of serial output wasn't worth 
the aggravation

and mapping through the host OS...
