Hi, I've wired up a carambola2 to a new board and am a little stuck. I've got some output from the console (below), but at the end of that the device stops and is unresponsive to serial commands (checking on a scope, I see the tx/rx pins going), so the system appears to be just stopped. Anybody have an idea why it's not booting or I can't get a response from uboot?
Thanks in advance, dean

Anybody got a working Carambola2 with a console attached?
If some kind soul can post a log of a working uboot boot sequence that might help in my troubleshooting.

[quote="adamheinrich"]Here is the U-Boot log you asked for. I did not notice your request earlier, sorry.
Thanks, Adam! So, I'm stumped as to why the module gets stuck there.
Anybody else have any suggestions?
I'll keep trying to get in touch directly with somebody at 8devices.

How do you have your Carambola connected? Is it the dev board or just the module? How do you power it?

Do you have it powered properly? Can't some current peak stop the module?
