Subject: [PATCH 0/2] Bluetooth: hci_qca: Fix WCN3990 firmware download
Date: Wed, 6 Mar 2019 16:40:39 -0800 [thread overview]
Message-ID: <20190307004041.38059-1-mka@chromium.org> (raw)
Firmware download to the WCN3990 often fails with a 'TLV response size
mismatch' error:
[ 133.064659] Bluetooth: hci0: setting up wcn3990
[ 133.489150] Bluetooth: hci0: QCA controller version 0x02140201
[ 133.495245] Bluetooth: hci0: QCA Downloading qca/crbtfw21.tlv
[ 133.507214] Bluetooth: hci0: QCA TLV response size mismatch
[ 133.513265] Bluetooth: hci0: QCA Failed to download patch (-84)
This is caused by a vendor event 'without command' that is misinterpreted.
Drop the event.
