Now the firmware has no tools to get HLog values, and the dsl_stats file has incomplete BPT (bits per tone) table only.
We plan to implement it and I will notify you when it become available.
It seems a mode switch button is broken. Try to manually switch it between A and B positions several times, then wait for next reboots. If this will not help to avoid unpredictable restarts, a sample should be replaced.
