Dear all,
I am using sumo release of Yocto Project. I have a QCA6174-5 chip which I would
use as wireless Access Point. I have added “linux-firmware” recipe to
IMAGE_INSTALL_append.
I can see the following kernel configuration:
CONFIG_NET_VENDOR_ATHEROS=y
CONFIG_ATH_COMMON=y
CONFIG_WLAN_VENDOR_ATH=y
CONFIG_ATH10K=y
CONFIG_ATH10K_PCI=y
I can also see the wlan0 interface in my target.
~# ethtool -i wlan0
driver: ath10k_pci
version: 4.14.98
firmware-version: WLAN.RM.4.4.1-00140-QCARMSWPZ-1
expansion-rom-version:
bus-info: 0000:01:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no
However I can’t use 5GHz band for wireless (for any country). CRDA and
wireless-regdb are installed. Hostapd software indicates (for channel=48,
hw_mode=a and country_code=US):
nl80211: Regulatory information – country=US (DFS-FCC)
nl80211: 2402-2472 @ 40 MHz 30 mBm
nl80211: 5170-5250 @ 80 MHz 23 mBm

nl80211: 5490-5730 @ 160 MHz 23 mBm (DFS)
nl80211: 5735-5835 @ 80 MHz 30 mBm

nl80211: Added 802.11b mode based on 802.11g information

nl80211: Mode IEEE 802.11b: 2412 2417 2422 2427 2432 2437 2442 2447 2452 2457
2462 2467[DISABLED][NO_IR] 2472[DISABLED][NO_IR] 2484[DISABLED]
[…]
Channel 48 (primary) not allowed for AP mode, flags: 0x4073 NO-IR
wlan0: IEEE 802.11 Configured channel (48) not found from the channel list of
current mode (2) IEEE 802.11a
wlan0: IEEE 802.11 Hardware does not support configured channel
Could not select hw_mode and channel. (-3)
With another driver/firmware ("kernel-module-qca6174" and "firmware-qca6174"
recipes) , ethtool shows "hif_pci" driver installed. All works fine. In this
case, I can use 5GHZ band. However I can’t change wlan txpower with: iw dev
wlan0 set txpower fixed 900 (for example, 900mBm = 9dB).
What driver/firmware or kernel configuration should I use to solve it?
Thanks very much in advance,
M del Mar
