Was it= only ever supported ?

May be NXP can free and shar= e the firmware source to the community, and let anyone who care try to debug= it ?

As far as my tests shown, the mwifiex driver n= ever has work correctly, and none version is sufficiently stable to be state= as working.

Please, NXP, take cares of your end cl= ients !
Be simple, be smart, be respectuous, give us the source=E2= =80=A6

Thanks in advance,

Hi Pali,

NXP doesn't have a plan to support mwifiex driver anymore. How should we han= dle this kind of retired project in upstream?

Thanks,

Hello Prashanth!

Thank you for reply. Did you have a time to check this issue?

G=C3=A9rald did a great testing which shows that version W16.68.1.p195 and higher of pcieuart8997_combo_v4.bin firmware does not work.
