I used Buildroot for the i.MX6UL EVK evaluation board, and that's working fine. I'm using Buildroot for our i.MX6UL based product, and the kernel boots and I can login, but shortly after that the console hangs.
I've tried the following:
* Set ulimits in a start-up script.
* Blink an LED. The LED stops blinking at about the same time as the console hangs.
* Check available memory; looks fine.
* Check /var/log/messages; looks fine.
* Check dmesg; nothing suspicious.
I'm hoping for suggestions on how to debug further.

Hello Steve,
There is no way to debug the console but you add printf to see whats happens for debugging linux you need ARM DS 5 or Lauterbach, Check this link for debugging:
