Subject: [PATCH] ath10k: fix boot failure in UTF mode/testmode
Date: Fri, 27 Jan 2017 19:21:38 +0530 [thread overview]
Message-ID: <1485525098-11548-1-git-send-email-c_traja@qti.qualcomm.com> (raw)
From: Tamizh chelvam <c_traja@qti.qualcomm.com>
Rx filter reset and the dynamic tx switch mode (EXT_RESOURCE_CFG)
configuration are causing the following errors when UTF firmware
is loaded to the target.
Error message 1:
[ 598.015629] ath10k_pci 0001:01:00.0: failed to ping firmware: -110
[ 598.020828] ath10k_pci 0001:01:00.0: failed to reset rx filter: -110
[ 598.141556] ath10k_pci 0001:01:00.0: failed to start core (testmode): -110
Error message 2:
[ 668.615839] ath10k_ahb a000000.wifi: failed to send ext resource cfg command : -95
[ 668.618902] ath10k_ahb a000000.wifi: failed to start core (testmode): -95
Avoiding these configurations while bringing the target in
testmode is solving the problem.
