Thanks for your patience. After further research dynamic_debug is not available on retail chromium os user systems for a variety of reasons, some of which you can find in this trail: https://bugs.chromium.org/p/chromium/issues/detail?id=188825. Given we need to be able to diagnose things in the field, this is not a good option for this. I hope this helps explain or justify the need for this interface. Thanks!
