My summary of the discussion was: - you mentioned some drawbacks you saw (like the mixture of trace output and printk output) - most of them look like addressed to me? (e.g. Steven showed a way to redi= rect printk to trace) - you posted your version (which was, however, marked as "not user friendly" even by yourself) - The discussion stalled over having two approaches So, I thought reposting would be a good way of finding out if your concerns were addressed in the discussion or not. If I overlooked something, I am sorry for that. Still, my intention is to continue the discussion, not to ignore it. Because as it stands, we don't have such a debugging mechanism in place currently, and with people working with DT overlays, I'd think it would be nice to have.
