E73 — ERROR_LOG_PARSE_FAILED

The error log stored in NVS could not be parsed.

What happens​

The error is logged once per boot, error_log_entries is set to an empty list, and the device proceeds to show the error log menu with no entries. This is non-critical — the device otherwise continues normally.

Possible causes​

  • The error log was written by an incompatible older firmware version using a different binary format.
  • The NVS entry containing the log is corrupted (e.g., a partial write from a crash during log saving).

How to fix​

  1. No action needed in most cases — The device ignores the unparseable log and continues normally. The corrupt entry will be overwritten next time an error is logged.
  2. Erase NVS and reflash — If this error appears on every boot and is accompanied by other NVS failures, a full flash erase may help.
