Yes, wpa_supplicant runs in AP mode using WEP security.

The system is ARM am335x running 5.4.8 kernel. The WLAN hw is wl18xx:
# ethtool -i wlan0
driver: wl18xx_driver
version: 5.4.8
firmware-version: Rev 8.9.0.0.79
expansion-rom-version:
bus-info: wl18xx.0.auto
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no
Embedded Linux distro is Buildroot (commit
208d3eb045551976dbaf507506b7048382e19b1f). Compiler GCC 9.3.0,
binutils 2.34.
The old working rootfs had wpa_supplicant 2.4 but I have also tested
it with the same kernel version 5.4.8. wpa_supplicant 2.10 has no
problem with WPA/WPA2 and no encryption. The only problem so far is
WEP.
Log attached.
Best regards,
Yegor
