88W8987 firmware download fail on android-10.0.0_2.6.0

[Simonum]

Hi NXP

I am doing test wifi driver on android-10.0.0_2.6.0 using Rockchip RK3399K (Android 10) + 88W8987.

Fail while loading FW image. I checked the HW and there is no problem.
Any advice on what to look at?
Please review my console messages.

Hi @Simonum @weidong_sun 

Are you able to resolve this issue?

If yes, could you please let us know what the root cause of the problem was.

Hello @Simonum ,

You konw, i.MX8MN-EVK supports 88W8987 module, we tested 8987 for many times on the board, android and linux OS.

Never encounterred the issue that FW downloading failed. But I have some suggestions for you and customer to debug it.

1. SDIO IO level.

According to SDIO protocol, when IO level of SDIO BUS is 1.8V, it can supports all speed mode, like 100MHz/200MHz etc.

So customer check if SDIO IO level is matched between CPU side and 88W8987 side.

2.  Trying to tune mmc node in device tree

we can add a line like below:

no-1-8-v;  // means , let us try SDIO 2.0, check if FW can successfully downloaded.

Regards,
