imx8mm evk could not turn on WiFi for android 10.0.0.2.3.0

• I've build android source code for android 10.0.0.2.3.0, and found it's failed to turn on Wi-Fi swich.
• for Android 10.0.0.2.0.0 and Android 10.0.0.1.0.0, I used the prebuilt demo image, it's ok to turn on Wi-Fi switch.
• I've compared the log and use command lsmod for 10.0.0.2.3.0 and Android 10.0.0.1.0.0, found that they used different drivers and different firmware for Wi-Fi.
  • 10.0.0.2.3.0 used mlan.ko (for nxp module)
  • 10.0.0.1.0.0 used wlan.ko (for QCA 9377)
• I've modify the source code for Android 10.0.0.2.3.0 to let wlan.ko to install and copy the related firmware to rootfs. But after boot, I got the error: 

  ar6k_wlan: probe of mmc0:0001:1 failed with error -1.

• Hope anyone could git me some hint, thanks.

We are using i.MX 8MM EVK with the latest Android 10.0.0_2.5.0 and Wi-Fi is not working as it is also using "QCA9377".

Any update or migration guide how to use the existing WiFi module for wireless connection?

Hello,

Yes you're correct for this release the i.MX 8M Mini EVK LPDDR4 board, BT function is supported as is (1PJ QCA9377).

Wi-Fi function for the other side is supported with the Wi-Fi expansion card (NXP 88W8987) plugged to the SD card slot.

Andorid Q10.0.0_1.0.0 still support both BT and Wi-Fi using the 1PJ QCA9377.

Unfortunately we have no plans to support QCA9377 in future releases.

Best regards,

Aldo.

1. After put the firmware for Wi-Fi to root file system, now it's ok to turned on Wi-Fi and scanning via setting UI.
2. But it's failed to connecting APs. The state transits between Saved and connecting.
