iMX6ULZ SDIO firmware issues

[jupiter_hce]

Hi,

When I used kernel 4.19, I connected iMX6ULZ SDIO using Marvel firmware linux-firmware-sd8801 for WiFi SDIO. Since I upgraded to kernel 5.10, the Marvell WiFi is broken, because Marvell WiFi group was acquired by NXP, could you please advise what Marvell SDIO firmware should be used for kernel 5.10?

Thank you.

Kind regards,

Hello @jupiter_hce ,

you can get firmware from the link: https://github.com/NXP/mwifiex-firmware/tree/master/mrvl, 

For 5.10.x linux bsp, you can find wifi release note here:

https://www.nxp.com/design/software/embedded-software/i-mx-software/embedded-linux-for-i-mx-applicat...

for wifi4, you can use iw416. see the release note, please!

Have a good day!

Hi weidong,

Thanks for your response and links, I actually already installed and run the firmware sd8801_uapsta.bin in our iMX6ULZ device.

Here are 2 issues:

(a) That firmware was running well for kernel 4.19, and it is broken when we upgraded to kernel 5.10.

(b) There is a bug in firmware to cause WiFi crash for WiFi reset, we tested both mwifiex reset or iMX6ULZ SDIO reset, both broken WiFi connections and could not be recovered, we have to run power reboot.

Are you able to fix those bugs?

Thank you.

Kind regards,

More information:

The WiFi chip is based on the Marvell Avastar 88W8801 chipset, any sd8801 firmware update or your Marvell engineers can fix it on kernel 5.10?
