Re: [beagleboard] serial console

[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

[beagleboard] serial console

[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
