Hello,
This is a follow-up on https://community.nxp.com/t5/Wireless-Connectivity/88W9098-radar-detection-not-working-hostapd-on-re...where I asked the same question.
At the time we did not have access to a version of the driver with DFS support, but that should now be the case; I am now running this version:
[27476.385234] wlan: version = PCIE9098--17.68.1.p126.15-MXM5X17345.p3-(FP68)
(I'm not sure how much is public about it, but according to the features pdf document it lists DFS radar detection for Japan)
Unfortunately I have the same problem as the original post, hostapd does not start:
# cat /etc/hostapd/hostapd.conf
interface=uap0
hw_mode=a
channel=56
country_code=JP
ssid=NXP_Demo
auth_algs=1
ieee80211n=1
ieee80211d=1
ieee80211h=1
wpa=2
wpa_key_mgmt=WPA-PSK
rsn_pairwise=CCMP
wpa_passphrase=123456789
# hostapd /etc/hostapd/hostapd.conf
uap0: interface state UNINITIALIZED->COUNTRY_UPDATE
uap0: interface state COUNTRY_UPDATE->DFS
uap0: DFS-CAC-START freq=5280 chan=56 sec_chan=0, width=0, seg0=0, seg1=0,
cac_time=60s DFS start_dfs_cac() failed, -1 Interface initialization failed
Looking at the documentation, I am starting to think I should setup a dfsX
iterface and perform the DFS scans out of band through mlanutl, and that the
automatic settings by hostapd are not supported; is that correct?
Thank you,
Dominique Martinet
Solved! Go to Solution.
Dear @martinetd
I asked kernel version, so I can try to reproduce your issue on same setup.
I checked on my side on the closest setup I have on my side:
- i.MX8MQ running 5.10.72 2.2.0
- driver release PCIE-WLAN-UART-BT-9098-U16-X86-17.68.1.p126.15-17.26.1.p126.15-MXM5X17345.p3_V0V1-GPL
- same hostapd config as yours
Please find attached the working log.
Regards,
Olivier
Dear Dominique,
Can you please confirm you are still using 5.10.72 kernel ?

Hello Olivier,
yes, I'm still running on a kernel based on 5.10.72 with the moal driver compiled from its release tarball -- should I try to update?
Thanks,
Dominique

hi @ocourson
Sorry for the slow reply, I caught covid last week and it took me a bit to catch up.
I could confirm that it works with the BSP image, so it is a problem in our userland.
It looks like running `iw reg reload` manually before starting hostapd makes it work for our device, so I'll investigate this further on my side. Sorry for the lack of proper testing and thank you for checking!
