Dear Russell King,

This works well in the lab during hardware bringup or BSP development.

But we are also interested in a solution that allows to get  more  or
less  automatic access to the log buffer content after a crash - when
you have several ten thousand systems in the field,  such  a  feature
can save you a lot of money.

Best regards,
