Re: [beagleboard] serial console

2020-12-19 Thread jonnymo 
Robert,

For the PocketBeagle, it seems a FTDI Click Board is recommended way to
connect to the serial output of the PB:

https://media.digikey.com/pdf/Data%20Sheets/GHI%20Electronics%20PDFs/PocketBeagleSystemRefManual_Web.pdf

See Jason's suggestion from this link:
https://github.com/beagleboard/pocketbeagle/issues/3

Is there anything else connected to the PB when trying to communicate with
it via serial? Is so, then you might try to disconnect it before reading
from the serial interface.


Cheers,

Jon

Hi,

My comments are in-line.

I guess my question is not very obvious;)

It's about the pocketbeagle.

Hi Robert,
I use this one on BBB/BBBW. It's a bit more expensive but you know it 
will work. The 6 pin connector fits directly to connector on BBB so you 
know the connections are correct.


My BBB and green work happily with such a cable and also with[1].

Can you please advise which serial adapter to use?

[beagleboard] serial console

2020-12-19 Thread robert.berger 
Hi,

I tried in a couple of ways to get something out of the serial console 
while booting (U-Boot, kernel, console,..)

This seems extremely unstable and random.

One device I tried is this[1] with 3.3V.

Another device is this[2].

Can you please advise which serial adapter to use?

Regards,

Robert
