Hello I am using the IMX7D running yocto warrior with a 4.19 kernel. I am trying to get the LBEE5XV1YM WiFi/BT module working. I have enabled the existing driver, loaded firmware that I found online:sdsd8997_combo_v4.bin
The driver seems to load successfully:

======
I try to enable wifi by using these commands (these commands worked on our previous hardware using a differenc wifi module):
wpa_supplicant -Dnl80211 -imlan0 -c/etc/wpa_supplicant.conf -B
sleep 5
udhcpc -i mlan0
Running these commands results in the following output:
Successfully initialized wpa_supplicant
rfkill: Cannot open RFKILL control device
IPv6: ADDRCONF(NETDEV_UP): mlan0: link is not ready
udhcpc: started, v1.30.1
udhcpc: sending discover
udhcpc: sending discover
udhcpc: sending discover
ieee80211 phy0: sched_scan start : n_ssids=1 n_match_sets=1
ieee80211 phy0: n_channels=41 interval=10 ie_len=0
The "udhcpc: sending discover" message prints forever and no network is created
Any thoughts on this? Do I need a different device firmware or driver perhaps?
Thanks,
Ben
