new Debian image problems on BeagleBone Black


We have a hearing aid project on a BBB. We have a lot of C code and .dtbo files for a cape on a Win 7 machine. Data was tranbsferred to and fro using PSCP

So far we have been using an old Debian image on the BBB which logged us on as 'root' without a password and the transfer worked fine. But that BBB died.

We have a spare BBB and I have just installed the latest image which requires logging on as 'debian' with password 'temppwd'

Problems:
1. I access the BBB via Putty. I have been doing this for a couple of years without problems. Putty now times out after about 10 seconds (although I've set 300 seconds). I then have to power down the Win7 machine to reconnect to the BBB. Ie the BBB is now useless

2. PSCP doesn't work. I have used the flag -pw to pass temppwd but without success.

Any thoughts

Peter

It doesn't sound like you are doing anything wrong here (ie using Putty to login to the default user), so it is going to be a matter of figuring out why it is failing. I'm assuming you are using the 19 Mar 2017 image?

Is Windows getting a valid IP address (ie not 169.x.x.x)?

When you say it 'times out', do you mean the log in succeeds, but then fails? Or just that it never logs in at all? Are you able to turn on the putty logging for some insight?

Are you able to connect a screen to the HDMI port? This would allow you to see the console to check that all is okay.

I'm guessing you have tried without the cape.

Also, are you running from the micro SD card, or burning it to the internal flash?

Are you sure of the power supply?

There is still a default root login (password 'root'), but passworded root login is no longer enabled by default on ssh.

Putty timing out

That was a week or two back - a long time in this business! - and the timeout problem went away. Thanks for thinking about it.

My problem now is getting the current Debian flasher image to load our own overlay.

I've tried a lot of things without success so I'm now going back to a 2015 Debian image which I used before and I'm pretty sure will work with our caps and overlay.
