88W8997 - Firmware loading fails

[swapnil]

We are unable to see NXP 88W8997 chipset firmware initialization getting failed while the Android boots. We are trying to boot Android Automotive OS 14 on iMX8QM.

Kernel version is - 6.1.55

Requesting your support on the same.

Dear @swapnil ,

OK, got it.

I will arrange time to test it next week.

due to no android auto bsp source code in my machine, so I have to make a new start, so  I need some time.

Thanks!

Regards,

weidong

Dear @weidong_sun ,

In the vendor partition, at path - /vendor/firmware/, pcieuart8997_combo_v4.bin as well as pcieuart9098_combo_v1.bin is present. With these files in place, the result is the same as mentioned in the above post.

Regards,

Swapnil

Dear @swapnil ,

I tested demo image, the version is : Android Automotive 14.0.0_1.1.0 (LF_v6.1.55 BSP)​​​​​​

Don't need to do any change, only need to install AW-CM276MA to M.2 Key E connector on i.mx8qm-mek board, then burn android images into emmc on board.

See below screenshot, please!

checked firmware files in the vendor path, see below, please!

It means that the default bsp supports 88W8997 & 88Q9098 / 88W9098.

Thanks!

Regards,

weidong

Dear @swapnil ,

In default android auto bsp, WiFi/BT based on pcie9098 chip is supported, not PCIe8997.

From your logs, it seems there doesn't exist the firmware of 88W8997.

So firmware of 88W8997, pcieuart8997_combo_v4.bin should be needed. According to your linux kernel version, you can get firmware from the link, then push it to corresponding directory on board ( the directory should be /vendor/firmware/), anyway, the firmware of 8997 should be the same directory as that of PCIE9098 (its firmware name is: pcieuart9098_combo_v1.bin)

-- getting firmware of 88W8997(PCIE interface)

https://github.com/nxp-imx/imx-firmware/tree/lf-6.1.55_2.2.0/nxp/FwImage_8997

Try it, please!

Then tell me your test result.

Thanks!

Regards,

weidong

Thanks @weidong_sun for the efforts you put in. We too had tried BT/WiFi Chipset based on PCIe 8997 on this demo image. Seems there might be some issue with the chip we are using.

Thank you!!

Let me share a similar malfunction on i.MX 8M Plus and I would request your cooperation to resolve my issue as well.

A very similar log was observed when the WiFi driver was installed via modprobe.

My case uses not Android but i.MX Yocto BSP userland. The kernel version and PCIe chipset were same as this thread owner. I suspect it happens due to the same reason though the tested SoCs are different.

Here's my environment.

• board : i.MX 8M Plus EVK
• M.2 slot : AzureWave AW-CM276MA
• kernel/userland : i.MX Yocto BSP imx-6.1.55-2.2.1

As long as I reproduced this, it frequently happened just on a cold boot and did not happen after rebooting by the reboot command.

Also, here's the failure log.
