Hi All,

   We have ported driver using NL80211 interface in Android 6 platform. Wi-Fi is up and connection established with Access point[Open/Secured].

After when we try to disconnect the connected Access point in android GUI, wpa_supplicant is crashing by signal 11.

Thanks,

Hi Thanaraj

this can be debugged using AN4553 Using Open Source Debugging Tools for Linux on i.MX Processors
http://www.nxp.com/assets/documents/data/en/application-notes/AN4553.pdf

note, nxp has Professional Services helping to port drivers
