[PATCH v1 0/3] Trigger reset if firmware status is abnormal when

Posted by Chris Lu 4 days, 12 hours ago

When the device unexpectedly restarts during previous firmware
download process, it can cause mt79xx firmware status to be
abnormal in the next attempt. In this case, a reset should be
performed to ensure everything starts afresh.

These changes include:
1. Optimizing the handling after the download function retry
   is exhausted, a reset should be performed.
2. Another download firmware command also needs to check status
   , and if an unexpected status occurs, trigger a reset.
3. Adding a flag "BTMTK_FIRMWARE_DL_RETRY": if download firmware
   process enters the reset mechanism, this flag will be set.
   After a successful setup, the flag will be cleared.
   If the flag is already set, no further reset attempts will be
   made to avoid endless reset retries.
