[beagleboard] Debug serial console not working

2021-07-02 Thread Vinayakumar Chikkadi
Hi

I am trying to get the debug serial working on Ubuntu for my beagle bone
black board.

I am powering up the BBB with the 5V 2A power adapter.

I am using the prolific usb to serial connector. After I connect the usb
cable & When I check on Ubuntu with dmesg | tail
I could see it’s getting enumerated as ttyUSB0
When I open with putty on the path
/dev/ttyUSB0 with 115200 8N1
I am not able to open the com port using putty.

Kindly suggest if any of the steps missing out here.

Best regards,
Vinay

WHICH "prolific usb to serial"?  They have a whole slew of different
models. And that doesn't count the packagers using a Prolific chip in their
products (cf:
https://www.amazon.com/prolific-usb-serial/s?k=prolific+usb+to+serial )
I'm guessing something similar to
https://www.amazon.com/Serial-Adapter-Signal-Prolific-Windows/dp/B07R8BQYW1/ref=sr_1_8?dchild=1&keywords=prolific+usb+to+serial&qid=1625245702&sr=8-8

I can't really help with Prolific -- most of my USB<>serial devices are
FTDI chips. I think the Adafruit 4-pin cable is the only Prolific chip
device I have.

Do you have privileges for the device? May not be relevant, but
connecting a USB<>Serial to the USB side of my BBB (I don't have a native
Linux desktop computer, and Windows won't be helpful to you) shows up like

crw-rw 1 root dialout 188,  0 Jul  2 13:21 /dev/ttyUSB0

the default user for the machine does belong to the dialout group.

I got the same thing for Debian running inside VirtualBox /after/
manually selecting the USB device from the VB0x menu...

BUT... unlike the BBB, my user account under VBox does NOT belong to
the dialout group, so I would have not permission to use it without making
changes...

It is interesting to see boot messages while the OS is coming up on BeagleBone

Hi Dennis,

Good day to you

I have given permission by running

sudo chmod 0777 /dev/ttyUSB0

Now I am able to open in putty but not receiving any data from bbb. Seems
the issue with usb to serial cable.

I got similar cable what you just mentioned on amazon.

Probably I would try to procure one from adafruit.

Thank you, it was of great help to me.
I would check with different cables and come back if problem persists.

Regards,
Vinay
